Optimization of Johnson–Cook Constitutive Model Parameters Using the Nesterov Gradient-Descent Method
Numerical simulation of impact and shock-wave interactions of deformable solids is an urgent problem. The key to the adequacy and accuracy of simulation is the material model that links the yield strength with accumulated plastic strain, strain rate, and temperature. A material model often used in e...
