Finite Element Modelling and Analysis of Impact of rods to rigid and deformable barriers. Taylor Impact Test. Ricochet

Keywords Impact, Taylor impact test, ricochet, contact interaction, Thermo-Elastic-Plastic coupled analysis, heating process
Programs in use LS-DYNA

In current project Taylor impact tests - impacting a fixed rigid surface with a cylindrical sample of material and ricochet processes were investigated with FE system LS-DYNA. The work results allowed to investigate material’s behavior at high stress and high strain rates and allowed predicting of rebounding processes.
