Hello!<\/p>\n
Consider: Denlinger, Erik R., Jarred C. Heigel, and Panagiotis Michaleris. “Residual stress and distortion modeling of electron beam direct manufacturing Ti-6Al-4V.” Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture 229.10 (2015): 1803-1813.<\/p>\n
In this work, the authors are performing a 3D thermal and mechanical analyses of an additive manufacturing process using one-way coupled transient thermal and quasi-static structural analyses. <\/p>\n
The authors state that: “The thermo-elasto-plastic model presented accounts for the observed stress relaxation by resetting both stress and plastic strain to 0 when the temperature exceeds a prescribed stress relaxation temperature.”<\/p>\n
I was wondering how this might be accomplished. How would I set stress and plastic strain to zero when the temperature exceeds a value? <\/p>\n
I am implementing my simulation in transient thermal and transient structural utilizing APDL command blocks. Is there an APDL command that can set stresses and plastic strains to zero? I already have code that is capable of finding the temperature of each element by looking at the nodal temperatures. <\/p>\n
Thank you!<\/p>\n","protected":false},"template":"","class_list":["post-284311","topic","type-topic","status-closed","hentry","topic-tag-3DTransientThermal-1","topic-tag-additive-manufacturing","topic-tag-ansys-apdl","topic-tag-apdl-commands","topic-tag-elastic-plastic-material","topic-tag-one-way-coupling-2","topic-tag-structural-and-thermal","topic-tag-transient-structural"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
