  • Finite element simulation of residual stress in direct metal laser sintering of AlSi10Mg built part: Effect of laser spot overlapping
    Materials Today: Proceedings, 2020
    Co-Authors: Ghulam Rasul Nazami, Bibhu Kalyan Panda, Seshadev Sahoo
    Abstract:

    Abstract Direct metal laser sintering is a metal-based additive manufacturing process used to make the components directly from the metal powders in a layered fashion. A high-intensity laser beam is used to fuse the metal powders during the scanning of the powder bed. In this process rapid heating and Solidification Take Place which leads to thermal stress in the build part that can affect the mechanical properties of the fabricated component. In the present work, a thermo-mechanical model was developed using a finite element approach to study the effect of laser spot overlapping on residual stress in the AlSi10Mg build part. From the simulation results, it was found that there was an increase in residual stress in the build part with increasing in laser spot overlapping.

  • Time-mass variation effects on solid layers formation around finned tubes
    World Renewable Energy Congress VI, 2000
    Co-Authors: S.s. Al Jandal
    Abstract:

    Publisher Summary This chapter discusses time–mass variation effects on solid layers formation around finned tubes. A number of investigations were performed on the effect of using different types of heat exchangers on the manner which solid layers form around cooled surfaces immersed in liquid PCM. Five types of heat exchanger arrangements were used and compared. A significant problem in the design of latent heat of fusion storage system is the accommodation of the melting and Solidification processes at a given time. During the process of melting energy is stored and energy is extracted when Solidification Take Place. Finally, the chapter concludes, that nondimensional time–mass correlations of the experimental and numerically predicted results were achieved using the surface areas (A/Auf) and solid mass (M/Muf) ratios as basis for analysis. Useful correlation coefficients in equations of the form M = C (Δt) n are presented and discussed in this chapter.
