LS-DYNA Analysis for Structural Mechanics Workshop II: Hourglass Control

This is the second Workshop in our FEA training course: LS-DYNA Analysis for Structural Mechanics. This course is geared toward the engineering professional simulating highly nonlinear, transient dynamic problems involving large deformations and contact between multiple bodies. A script of the Workshop is as follows: Isoparametric Shell/Solid Elements and Hourglassing* • All under-integrated isoparametric elements (one Guass point) have hourglassing present. It is a non-physical “zero-energy” mode of defor
