Abstract

The paper discusses the response of a layered cladding to a pressure pulse and the associated energy absorption, which depends on the geometry of a single layer and the material properties. The dynamic loading is modelled as a triangular pulse with a duration of milliseconds. Isotropic work hardening with dynamic yield properties according to the Cowper-Symonds relation is employed to model a steel layer, while a strain rate insensitive isotropic work hardening material model is used for analysing the response of an aluminium layer. The efficiency of the layered claddings in the design of blast resistant structures is discussed. 1 Introduction The purpose of designing layered claddings is to reduce the energy transmitted to the main structure fo
