Microstructure-Based Modeling of Laser Beam Sha** During Additive Manufacturing
Recent experimental studies suggest the use of spatially extended laser beam profiles as a strategy to control the melt pool during laser powder bed fusion (LPBF) additive manufacturing. However, linkages conn...

A coupled fluid-mechanical workflow to simulate the directed energy deposition additive manufacturing process
Simulation of additive manufacturing processes can provide essential insight into material behavior, residual stress, and ultimately, the performance of additively manufactured parts. In this work, we describe...

Computation of Effective Radiative Properties of Powders for Selective Laser Sintering Simulations
Selective laser sintering (SLS) is an additive manufacturing technique for rapidly creating parts directly from a computer-aided design (CAD) model by using a laser to fuse successive layers of powder. However...
