Compressive Properties of Corevo^® Foam under Uni-Axial Loading Based on Experimental and Numerical Analysis

Abstract:

This manuscript investigates the compressive properties of Corevo^® foam. Corevo^® foam is a cellular metal manufactured by the infiltration casting of salt dough with aluminium. Corevo^® foam samples with different porosities are tested by using quasi-static compression loading. Their mechanical properties (i.e.: effective Young’s modulus, Poisson’s ratio, initial yield stress and material yield stress) are then compared to reveal the importance of the density difference. In addition, three-dimensional finite element analysis is performed on models generated from micro-computed tomography (μCT). The results of two different pore sizes are obtained and compared in the scope of this work. These numerical results are verified by comparison with the experimental analysis. A sound agreement is found. Numerical analysis in this work also includes the investigation of the mechanical material anisotropy and plastic deformation.
