Calibration of the Bodner-Partom Constitutive Model for Vacuum Packed Particles Using Simulated Annealing Algorithm

The work is related to the numerical modeling of Vacuum Packed Particles (VPP)-structures composed of grains enclosed in an elastic envelope and submitted to internal underpressure. The behavior of the material is modeled using viscoplastic law of Bodner-Partom. The inverse problem of constitutive model parameter identification is solved using the non deterministic optimization procedure based on simulated annealing algorithm. The results of numerical simulation are compared with experimental results.
