Residual stress evaluation in selective-laser-melting additively manufactured titanium (Ti-6Al-4V) and inconel 718 using the contour method and numerical simulation (2018, methodology): “Thermo-mechanical numerical prediction showed tensile residual stresses approaching 300 MPa in the top layer of a cantilever sample along its length direction, which were significantly reduced after removing the sample from the base plate [10].”
Advances in additive manufacturing process simulation: Residual stresses and distortion predictions in complex metallic components (2020, methodology): “Commercial finite element-based software packages have recently released AM modules or provide in-built functionalities capable of simulating various approaches of thermomechanical analysis to predict printed part microstructure, stresses and distortions via (1) detailed Goldak or Gauss-type heat so”
