  • Stress Analysis of rolling bearings based on pro mechanica
    Journal of Harbin Bearing, 2008
    Co-Authors: Swz Heavy
    Abstract:

    The Stress Analysis have great significance for those bearing bear with heavy load.Now the Stress Analysis of rolling bearings is carried out by using general finite element Analysis software(e g.ANSYS.MARC).The paper is aimed at the defect of general finite element Analysis software used in bearing Stress Analysis,and discuss to establish rolling bearing model directly by using Pro/ENGINEER and to analyze by using Pro/MECHANICA.These Analysis value in comparison with ANSYS value,the paper discusses Pro/MECHANICA Analysis method is applied in bearing Stress Analysis.

  • Carotid Plaque Stress Analysis: Issues on Patient-Specific Modeling
    Multi-Modality Atherosclerosis Imaging and Diagnosis, 2013
    Co-Authors: Hao Gao, Quan Long
    Abstract:

    Plaque Stress Analysis has been widely studied for understanding the mechanism of plaque initiation, development, and rupture. With development of computational power and medical imaging technique, plaque Stress Analysis has evolved from simplified 2D idealized mathematical model to much more complex model with 3D patient-specific structure. In this chapter, two issues regarding patient-specific plaque Stress Analysis have been studied: (1) patient-specific geometry and (2) patient-specific material properties. By using multispectral carotid MRI, 3D plaque geometries were reconstructed for one symptomatic patient and one asymptomatic patient with multicomponents, the followed plaque Stress Analysis showed plaque Stress in the symptomatic patient had much higher value than that in the asymptomatic patient. Furthermore by analyzing carotid artery motion in one cardiac cycle, an anisotropic material model was fitted to the motion pattern of the selected carotid artery section. Then the fitted patient-specific material model was successfully applied to plaque Stress Analysis for the corresponding plaque sample. It is believed that plaque Stress Analysis with patient-specific modeling will be helpful in the identification of high-rupture risk patients.

  • Atherosclerosis Plaque Stress Analysis: A Review
    Multi-Modality Atherosclerosis Imaging and Diagnosis, 2013
    Co-Authors: Hao Gao, Quan Long
    Abstract:

    Stroke has been considered to be one of the leading causes of death all over the world. Although many studies have been conducted to understand the mechanism of plaque rupture, which leads to stroke, the exact mechanism still remains unclear. It has been widely accepted that both plaque morphology and biomechanical environment of the plaques will affect plaque vulnerability. Since 1990s, many studies have been devoted to plaque Stress Analysis in order to demonstrate the possible links between plaque rupture and abnormal plaque Stress conditions. In this chapter, plaque wall Stress Analysis will be reviewed from 2D to 3D, from idealized models to patient-specific plaques in terms of geometrical accuracy, and from structure Analysis only to fluid–structure interaction (FSI) Analysis, with computational examples from our group.

  • Introduction to thermoelastic Stress Analysis
    Strain, 1999
    Co-Authors: J. M. Dulieu-barton
    Abstract:

    The theory of thermoelastic Stress Analysis is reviewed and the assumptions in developing the theory are assessed. The equipment for thermoelastic Stress Analysis is based on infra-red detection systems. The commercially available systems are described and appraised. Techniques for calibrating the output from the detectors are also provided.

  • Development and applications of thermoelastic Stress Analysis
    Journal of Strain Analysis for Engineering Design, 1998
    Co-Authors: J. M. Dulieu-barton, Peter Stanley
    Abstract:

    AbstractThe theory of thermoelastic Stress Analysis is reviewed and the implications of some theoretical developments are assessed. Available instrumentation is described and techniques available for separation of individual Stress values are summarized. The scope of the technique is illustrated with reference to a number of applications covering crack-tip Stress studies, Stress Analysis and damage assessment in composite materials, and ‘field’ work on a traffic-loaded road bridge.
