| Abstract Scope |
Simulating the wire arc additive manufacturing (WAAM) process can be challenging due to the large part size. An improved workflow that combines automation and GPU accelerated modeling using the Pittsburgh Additive Manufacturing Simulator (PAMSIM) has been implemented. Although thermal simulations are very fast, thermomechanical simulations can take 10 to 20 times more time and thus become impractical to implement before every print. This work focuses on implementation of an automated computational framework for the flash heating method combined with the temperature dependent inherent strain. The improved workflow helps to accelerate the manufacturing process of new parts using WAAM, through thermal and residual stress results at the part scale level. |
