  • [Show abstract] [Hide abstract] ABSTRACT: A three-dimensional transient finite element model was developed to evaluate the thermal performance of an attic radiant barrier system as an energy-efficient insulation technology. The finite element model simulates different heat transfer modes including convection, radiation, and conduction. Hourly experimental data collected in a housing complex in Zachary, LA, were used to validate the finite element analysis. Upon validation, the design variables and their influence on the performance of the radiant barrier insulation system were investigated. Among the different design variables, the presence of an air gap on both sides of the radiant barrier had a significant effect on the performance of the insulation system.

  • [Show abstract] [Hide abstract] ABSTRACT: The precipitation of a solid phase in a rigid matrix leads to the creation of strain energy in the system as the transformation strain cannot be relaxed in the case of solid state transformations. A finite element model based on the initial strain approach has been presented to evaluate elastic accommodation energies during solid-state transformations. The finite element analysis (FEA) reveals that the total system energy increases with increase in the ratio of the modulus of the precipitate to that of the matrix, and with increase in misfit strain between the matrix and the precipitate. The analysis has been performed by considering the transformation to progress from the centre to the surface and from the surface to the centre of the three dimensional axisymmetric system. The elastic accommodation energies obtained by the FEA are comparable to energies obtained by continuum mathematical models.

  • [Show abstract] [Hide abstract] ABSTRACT: We are developing techniques for finite element analysis of human joints. These techniques need to provide high quality results rapidly in order to be useful to a physician. The research presented here increases model quality and decreases user input time by automating the volumetric mesh generation step.
