Cohesive modeling of ductile dynamic failure of pressurized metallic structures
Last modified: 2013-05-03
Abstract
Dynamic crack propagation of pressurized aluminum vessels has been studied. Rate insensitive
cohesive zone models overpredict the rate of fracture. This was the motivation to implement a new
Perzyna cohesive zone model, which is able to explain the low measured crack speeds.
