WebJan 1, 2009 · Crushable foams are mainly used in cushioning, impact mitigation, energy absorption, and comfort applications [2]. ... ... Difficulties arise in modelling these types of materials because they... WebCrushable foams undergo deformation by ductile plasticity or brittle means. In ductile behaviour, the foam walls undergo plastic deformation with little or no recovery. Classic examples are metallic foams. The cell walls in brittle foams fail, on the other hand, and there is no recovery. Rigid polyurethane foams fail in this manner.
http://abaqus-docs.mit.edu/2024/English/SIMACAEMATRefMap/simamat-c-ratedependent.htm WebFoam concrete is a highly cellularized cementitious material that undergoes extensive plastic deformation when loaded to failure. Under compression, the microstructure of low-density foam concrete gets progressively crushed at a steady stress stage, accompanied by substantial energy dissipation.
WebFeb 1, 2011 · The crushable foam model uses an elliptical yield surface in deviatoric stress and hydrostatic stress plane, and requires two parameters: (1) compression yield ratio which is defined as the ratio of initial yield stress in uniaxial compression to initial yield stress in hydrostatic compression, (2) hydrostatic yield stress ratio which is defined …
