10 Collapse of industrial structure (Midwest Steel, Inc 2008) Cohesive Zone Model Collapse of structure vs. fracture failure using CZM: elements are disassociated CZM “has mainly been applied” to brittle materials in continua. Limited CZM studies for ductile materials “on a structural scale” Develop CZM-based macro-model � Efficient � Cyclic loadings Fracture failure using Cohesive Zone Model (CZM) approach (Zhang, 2003)
