IMPROVEMENT IN ANALYSIS OF QUASI-STATIC COLLAPSE WITH LS-DYNA

Quasi-static collapse simulations of thin-wall-tubes are performed with Ls-Dyna code. To reduce the computational time, the speed of quasi-static loading is increased. Studies are conducted with different loading speeds. A range of the load speed used for the simulation is specified. This method is compared with Mass Scaling method integrated into Ls-Dyna.
