Abstract Scope |
Novel materials like composite metal foams (CMF) can provide high strength to density ratio and enhanced energy absorption capabilities to mitigate puncture and bolster structural integrity of HAZMAT tank cars during potential derailments. This work summarizes quasi-static numerical model of multi-phase steel-steel CMF, incorporating interactions between embedded hollow metal spheres with entrapped fluid (air) within a metallic matrix, and provides a glimpse of the extension of this approach to dynamic impact scenarios in future works. The metallic components and the air trapped within spheres are modeled using solid Lagrangian elements and smooth particle hydrodynamics (SPH), respectively and the fluid-solid interactions are implemented using contact definitions. The numerical model for quasi-static compression reports an average percentage error of 2.2% for plateau region and a percentage error of 5.9% for densification strain when compared against experimentally obtained data. |
