Crushable foam distortion control
WebFeb 27, 2014 · Abstract. Triaxial test data from the University of New Mexico and uniaxial test data from W-14 is used to calibrate the Abaqus crushable foam material model to represent the syntactic foam comprised of APO-BMI matrix and carbon microballoons used in the W76. The material model is an elasto-plasticity model in which the yield strength … Web3’-wide and the 60" and 90" tapered sizes. The LMC replaces the crushable cartridge with a resilient elastometric cartridge. The Quadguard Elite is a low maintenance system that …

WebModels for crushable foams. Abaqus uses two phenomenological constitutive models for the analysis of crushable foams typically used in energy absorption structures. Both the volumetric hardening model and the isotropic hardening model use a yield surface with an elliptical dependence of deviatoric stress on pressure stress in the meridional plane.
