WebA new feature named tube adaptivity for sheet metal forming is implemented in LSDYNA. It conducts adaptive mesh fission/fusion at - the beginning of an adaptive step according to a predefined load path and a set of user defined parameters. Webvarying wall angle conical frustum was simulated using shell elements with different element edge lengths and adaptive mesh. Effects of these mesh parameters on plastic strain, punch force and form accuracy of deformed geometry has been studied. The necessary simulations for this study are performed using explicit finite element code LS-DYNA. assistant\u0027s 7y https://baileylicensing.com
