Abstract In the present work, a state-based peridynamics with adaptive particle
refinement is proposed to simulate water ice crater formation due to impact loads. A
modified Drucker-Prager constitutive model was adopted to model ice and was
implemented in the state-based peridynamic equations to analyze the elastic-plastic
deformation of ice. In simulations, we use the fracture toughness failure criterion in
peridynamics to simulate the quasi-brittle failure of ice. An adaptive particle refinement
method in peridynamics was proposed to improve computational efficiency. The results
obtained using the peridynamic model were compared with the experiments in previous
literatures. It was found that the peridynamic… More >
