On the ballistic resistance of double-layered steel plates: An experimental and numerical investigation (2007, methodology): “For targets impacted by blunt projectiles the mesh was fixed, and previous results reported by Dey et al. (2004) on 12 mm thick monolithic Weldox 700 E targets are included for comparison with the double-layered configurations.”
Damage accumulation and fracture initiation in uncracked ductile solids subject to triaxial loading (2007, background): “For instance, Børvik et al. (2001) considered that there exists a threshold of plastic strain below which no damage is accumulated.”
A non-ordinary state-based peridynamics formulation for thermoplastic fracture (2016, background): “Hence, the JC constitutive model by considering damage can be written as [39]”

Perforation resistance of five different high-strength steel plates subjected to small-arms projectiles (2009, result): “A slightly modified version of the Johnson–Cook constitutive relation [28,29] (called the MJC model in the following to distinguish it from the original model), found to give reliable results in previous studies on impact of steel plates (e.”
