  • Pressure Vessel Design simulation implementing of multi swarm particle swarm optimization
    International Conference Software and Computer Applications, 2019
    Co-Authors: Sinan Q Salih, Abdulrahman A. Alsewari, Zaher Mundher Yaseen
    Abstract:

    The new era knowledge of optimization algorithm is massively boosted recently. Among several optimization models, multi-swarm approach has been proposed most recently for balancing the exploration and exploitation capability through the Particle Swarm Optimization (PSO) algorithm. The proposed multi-swarm model which is called Meeting Room Approach (MRA), is tested and evaluated based on solving normal and large-scale problems. In the current research, the feasibility of the proposed Multi-Swarm Particle Swarm Optimization (MPSO) is adopted to simulate mechanical engineering problem namely Pressure Vessel Design (PVD). The results indicated the potential of the proposed MPSO model on simulating the PVD problem with optimum solution over the standalone PSO. Further, the current study results authenticated against other famous meta-heuristics models. Overall, MPSO reported an excellent optimization solution with fast convergence learning process.

  • Assessment of DBA-L Pressure Vessel Design Method by a Cylindrical Vessel with Hemispherical Ends
    MATEC Web of Conferences, 2019
    Co-Authors: Ren Xincheng, Xun Huang
    Abstract:

    Stress categorization is an essential procedure in Design by Analysis (DBA) Pressure Vessel Design methods based on elastic analysis in ASME and EN code. It was difficult to implement especially around structural discontinuities. A new elastic analysis, DBA-L, was proposed recently to avoid stress categorization. A model of the cylindrical Pressure Vessel with spherical end is used to check the validity of this method by comparing with other Design methods based on stress categorization procedures and elastic-plastic stress analysis from ASME and EN code. The results indicate that the DBA-L is an economic and explicit method, and can be used an alternative method to stress categorization.

  • Evaluation of DBA-L Pressure Vessel Design method by 2D and 3D solid models
    Thin-Walled Structures, 2019
    Co-Authors: Zhewei Zhou, Yeping Xie, Xun Huang
    Abstract:

    Abstract The Pressure Vessel Design method base on elastic analysis in ASME Design code includes a stress categorization procedure. It is not obvious to distinguish the primary and secondary stresses, especially in geometric discontinuities. The DBA-L method has been proposed recently to avoid stress categorization. In this paper, the effectiveness of the DBA-L Pressure Vessel Design method is assessed by comparing with other Design methods through three Vessels: a cylindrical Vessel with thick flat end under internal Pressure, a dished end with nozzle in knuckle region under Pressure and a cylindrical-nozzle intersection. It is found that the DBA-L method successfully predicted reasonable allowable loads and can be used as an alternative method to stress categorization method.

  • Reliability assessment of Pressure Vessel Design methods
    International Journal of Reliability and Safety, 2019
    Co-Authors: Li Hongjun, Xun Huang, Yang Peng, Yang Hui
    Abstract:

    Several Pressure Vessel Design methods based on elastic analysis and elastic-plastic analysis are available to Designers. This paper proposes a reliability analysis method to assess three Pressure Vessel Design methods: Stress Categorisation Method (SCM), Limit-Load Analysis (LIMIT) in ASME code and DBA-L method which was recently proposed by present authors. It was concluded that with the same input variables into the three analyses, the responses of calculated results of three method were different, which provided an effective guidance to assess and choose the proper Design method in engineering practice.

  • A new Pressure Vessel Design by analysis method avoiding stress categorization
    International Journal of Pressure Vessels and Piping, 2017
    Co-Authors: Li Hongjun, Xun Huang, Yang Peng, Yang Hui
    Abstract:

    Abstract Stress categorization in the Design by analysis (DBA) procedure for protection against plastic collapse in Pressure Vessel has been problematic during application. For example, it is difficult to determine the proportion of primary and secondary stress at the gross structural discontinuities. This paper proposes a new method to avoid the stress categorization by extending the current elastic stress analysis method in ASME Code based on lower bound limit load theory. The proposed method assumes a stress distribution along the stress classification line (SCL) in the form of limit stress state for a beam under membrane and bending load, rather than a linear stress distribution. The effectiveness of proposed method is verified by comparing with the elastic stress analysis, Limit-Load Analysis, Elastic-Plastic stress Analysis of the ASME Code for axisymmetric Pressure Vessels. The results concluded that the new method is effective easy to use.

  • A New Method of Stress Linearization for Design by Analysis in Pressure Vessel Design
    Applied Mechanics and Materials, 2014
    Co-Authors: Hong Jun Li, Qiang Ding, Xun Huang
    Abstract:

    Stress linearization is used to define constant and linear through-thickness FEA (Finite Element Analysis) stress distributions that are used in place of membrane and membrane plus bending stress distributions in Pressure Vessel Design by Analysis. In this paper, stress linearization procedures are reviewed with reference to the ASME Boiler & Pressure Vessel Code Section VIII Division 2 and EN13445. The basis of the linearization procedure is stated and a new method of stress linearization considering selected stress tensors for linearization is proposed.

    Abstract:

    Recently the development of optimization algorithm is rapidly increased. Among several optimization algorithms, Harmony Search (HS) has been recently proposed for solving engineering optimization problems. The HS has some weaknesses such as parameters selection and falling in local optima. Many variants proposed to solve these problems. This paper presents successful hybrid algorithms with high performance to solve the Pressure Vessel Design simulation. The hybrid algorithms consist of well-known variants of HS and an opposition-based learning technique. The hybrid algorithm improved the HS exploration and avoiding falling in local optima, which lead the algorithm to provide significant results.

  • True global optimality of the Pressure Vessel Design problem: a benchmark for bio-inspired optimisation algorithms
    International Journal of Bio-Inspired Computation, 2013
    Co-Authors: Xin-she Yang, Christian R. Huyck, Mehmet Karamanoglu, Nawaz Khan
    Abstract:

    The Pressure Vessel Design problem is a well-known Design benchmark for validating bio-inspired optimisation algorithms. However, its global optimality is not clear and there has been no mathematical proof put forward. In this paper, a detailed mathematical analysis of this problem is provided that proves that 6,059.714335048436 is the global minimum. The Lagrange multiplier method is also used as an alternative proof and this method is extended to find the global optimum of a cantilever beam Design problem.

  • Fatigue Analysis in Pressure Vessel Design by Local Strain Approach: Methods and Software Requirements
    Journal of Pressure Vessel Technology, 2005
    Co-Authors: Arturs Kalnins
    Abstract:

    The purpose, methods for the analysis, software requirements, and meaning of the results of the local strain approach are discussed for fatigue evaluation of a Pressure Vessel or its component Designed for cyclic service. Three methods that are consistent with the approach are evaluated: the cycle-by-cycle method and two half-cycle methods, twice-yield and Seeger's. For the cycle-by-cycle method, the linear kinematic hardening model is identified as the cyclic plasticity model that produces results consistent with the local strain approach. A total equivalent strain range, which is entered on a material strain-life curve to read cycles, is defined for multiaxial stress situations .

  • Fatigue Analysis in Pressure Vessel Design by Local Strain Approach: Methods and Software Requirements
    Pressure Vessel and Piping Codes and Standards, 2004
    Co-Authors: Arturs Kalnins
    Abstract:

    The purpose, methods for the analysis, software requirements, and meaning of the results of the local strain approach for fatigue analysis in Pressure Vessel Design is discussed. Three methods that are consistent with the approach are evaluated, based on the requirement that the calculated stress-strain behavior of a stabilized cycle in a Pressure Vessel component offers a valid comparison with that of the smooth specimens used to develop the cyclic stress-strain curve of the material. Software that can produce results consistent with the approach is identified. The question of the kind of multiaxial equivalent strain range that should be used in the local strain approach is addressed and answered. The concept of a multiaxial equivalent hysteresis loop, which replaces multiple hysteresis loops between stress and strain components, is developed. Its purpose is to determine the multiaxial equivalent stress and strain ranges that are consistent with the local strain approach.Copyright © 2004 by ASME
