FE modeling of the crash-test for energy-absorbing composite lighting colums

Finite element analysis of the steel cable failure with consideration of contact interaction between cable plies

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.

In current project penetration process of long rod into semi-infinite target connected with the heating process was investigated with FE system LS-DYNA. The impact velocity is 2347 m/s. In view of complexity of problem the behavior of steel long rod and target was modeled as Thermo-Elastic-Plastic one. The results of investigation are in a good agreement with experimental data.

In current project spall crack formation process was investigated with FE system LS-DYNA. Impact of thin plate-impactor to target from titanium alloys was performed. The presented FE modeling shows the process of experimental determining of material resistance for scabbing failure. FE results were verified with experimental data. The work results allowed predicting spall crack formation, investigation of scabbing processes.
