dc.description.abstract | This paper propose a methodology to identify the dynamic material properties of the HAZ near the base metal in a resistance spot weld at various strain rates. The mechanical properties of the HAZ of SPRC340R were obtained by fabricating thermal simulated HAZ specimens which have similar hardness and microstructure as the actual weld HAZ near the base metal. The thermal simulated HAZ specimens are fabricated using the Material Thermal Cycle Simulator (MTCS). Then, dynamic tensile tests are performed at various strain rates of 0.001 /sec to 100 /sec. Finite element analysis of tensile-shear tests were done under the static and dynamic loading conditions to verify the validity and effectiveness of thermal simulated HAZ properties. Load and displacement curves were obtained with and without applying the material properties of HAZ. The curves are compared to the experimental data. The amount of errors between the analysis and experiment were reduced when the material properties of thermal simulated HAZ were applied to the HAZ. The comparison demonstrates that the dynamic material properties obtained from thermal simulated HAZ specimens are valid for the analysis of spot welded specimens. | - |
