Critical Damage Evolution model for spall failure of ductile metals
TL;DR: In this article, a Critical Damage Evolution (CDE) model considering void growth and coalescence is proposed for describing the dynamic tensile spall of ductile metals sustaining intense dynamic loading.

Large strain computational modeling of high strain rate phenomena in perforating gun devices by Lagrangian/Eulerian FEM simulations
TL;DR: In this paper, a critical review of the constitutive modeling of materials subjected to large strains and high to very high strain rate behavior of materials and components is presented, and the results are compared to those obtained from the original Johnson-Cook model.

Damage evolution and spall failure in copper under complex shockwave loading conditions
TL;DR: In this paper, the damage evolution and spall behavior of copper under complex shockwave loading conditions were investigated using plate impact experiments with conical targets, where sweeping tensile waves were generated by the interaction of the released waves that were reflected from the free surfaces of the impactor and the cone surface.

Mitigation of spall fracture by evolving porosity
TL;DR: In this article , the authors report on finite deformation finite element calculations that analyze the response of porous ductile materials subjected to impact loading conditions and show that porosity in ductile material can, under certain circumstances, mitigate spall fracture by attenuating stress waves.
