thermo mechanical modeling of Thermal Stress in metal additive manufacturing considering elastoplastic hardening
Cirp Journal of Manufacturing Science and Technology, 2020Co-Authors: Elham Mirkoohi, Daniel E Sievers, Hamid Garmestani, Steven Y LiangAbstract:Abstract The build-up of Thermal Stress induced by a high-temperature gradient in an additively manufactured part during laser metal additive manufacturing provides significant limitations to the adoption of this process since Thermal Stress may induce high tensile residual Stress and part distortion in the additively manufactured parts. Herein, a thermomechanical analytical model is proposed to predict the in-process elastoplastic hardening Thermal Stress and strain for single-track scan strategy. The Thermal model is validated using experimental results of melt pool geometry. Also, finite element simulation is performed to validate the proposed elastoplastic hardening Thermal Stress model of the same problem.

Estimating Thermal Stress in BIPV modules
International Journal of Energy Research, 2006Co-Authors: P. Konttinen, Thomas Carlsson, Peter Lund, Teijo LehtinenAbstract:SUMMARY The Thermal Stress on building-integrated photovoltaic modules (BIPV) in Espoo, Finland, was studied with field-testing of amorphous silicon modules. Based on these results, the Thermal Stress at two other European locations (Paris and Lisbon) was estimated. The estimation procedure entailed Thermal
