Abstract

The present work presents both numerically and experimentally the quasi-static lateral compression of nested systems with vertical and inclined side constraints. The force–deflection response of mild steel short tubes compressed using two types of indenters is examined. The variation in response due to these indenters and external constraints and how these can contribute to an increase in the energy absorbing capacity of such systems are illustrated. The implicit version of the Finite Element code via ANSYS is used to simulate these nested systems and comparison of results is made with those obtained in experiments and were found to be in good agreement.
