Impact perforation of sandwich panels with graded hollow sphere cores: Numerical and Analytical investigations

Impact perforation of sandwich panels with graded hollow sphere cores: Numerical and Analytical investigations

In this study, we numerically and analytically investigate the impact perforation of sandwich panels made of 0.8 mm 2024-T3 aluminum alloy skin sheets and graded polymeric hollow sphere cores with four different gradient profiles. A suitable numerical model was conducted using the LS-DYNA code, cali...
