Beschreibung: A new simulation infrastructure for predicting the effects of changes in process parameters on mechanical properties, residual stress/strain, crystal structure, and other micro & macro features of components made using metal-based AM techniques has been developed at the University of Louisville (UofL) and is being commercialized by 3DSIM, LLC. Based upon its MatLab and Fortran code, UofL personnel predicted their multi-scale, multi-physics finite element solvers should solve for thermal history and residual stress evolution many orders of magnitude faster than competing tools while achieving better solution accuracy. In order to test this contention, a series of computational experiments were designed to benchmark the performance of the code being commercialized by 3DSIM against a well-respected simulation tool, ANSYS. The results of these initial studies indicate the 3DSIM architecture is significantly faster than ANSYS for simulating metal-based AM processes. ; Mechanical Engineering
