Predicting material strength, damage, and fracture The synergy between experiment and modeling

Abstract

The Taylor cylinder impact test, the plane-strain tensile test, and explosively driven hemisphere test represent readily conducted experiments that probe the deformation, damage evolution, and fracture behavior of materials. Because these tests are very sensitive to large gradients of stress, strain, strain rate, and shock loading, we are using them to evaluate and validate the correctness of our mechanical models that are implemented and destined to be implemented into large-scale 3-D simulation codes.
