Loading and Unloading Curve of Foam Material Based on Compression Test

Abstract

This paper is deals with compression testing for the purpose of identify loading and unloading curves of polyurethane foam materials. Obtained testing results of foam are used for a mathematical description of the material behaviour. The mathematical description is applied to a finite-element analysis for the purpose of simulation and comparison with the actual compression test.
