How to simulate Honeycomb Sandwich structure with foam projectile in Abaqus?

01 January 1970 1 576 Report

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 follows

Face 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

How to define and get results (stresses) for certain points of a model in abaqus, using python? When the size of the model changes?

I want to do a parameter study of a aixsymmetric cylinder in Abaqus. I want to create several jobs where I get the stresses for 3 different points in my model. These points are defined. I wrote a...
