I am trying to reproduce the results of this paper Article The structure response of sandwich beams with metallic auxet...
I tried with many combinations but unable to reproduce. As I am a beginner to Abaqus, unable to understand the problem with my simulation. Please help me out with this. Details are as followsFace Sheets and Core are rigid Perfectly plastic
Foam Projectile - Crushable foam - Isotropic Hardening
Surface - Surface contact between Projectile and Top FaceSheet
General contact for all other interactions
Predefined Velocity Field - 205000 (mm/s)
Used Consistent units throughout
Mesh - C3D8R for all instance
Simulation time - 0.025
Thank you for time
