مقاله جوشكاري Finite element analysis of resistance spot welding process
مقاله جوشكاري با عنوان : Finite element analysis of resistance spot welding process
Guo Zhong
چكيده :
A coupled finite element model is developed to
analyze the transient thermal and mechanical behaviors of
Resistance Spot Welding (RSW) process using commercial
software ANSYS. A direct-coupled electrical-thermal Finite
Element Analysis (FEA) is firstly performed to simulate the
transient thermal characteristics of RSW process. The thermal
history of the whole process and the temperature distribution of
the weldment are obtained through the analysis. Then based on
the thermal results a sequential coupled thermo-elastic-plastic
analysis is conducted to determine the mechanical features of
RSW process. The mechanical features, including the
distributions of the contact pressure at both the faying surface
and the electrode-workpiece interface, the stress and strain
distributions in the weldment and their changes during the RSW
process and the deformation of the weldment are also calculated.
