Extraction of rate-dependent fracture properties of adhesive interface involving large-scale yielding

摘要: Interface debonding is one of the major failure modes for adhesive joints polymer–matrix composites. The interfacial fracture properties interfaces involving large-scale yielding difficult to determine. A hybrid method that combines modified data reduction and inverse analysis was used determine energy composite propellant/insulation interface at different loading rates. adopts effective crack length account effect progress zone avoid monitoring length. These estimated values were then calibrated by based on Hooke–Jeeves algorithm in which layer characterized a cohesive model. whole process conducted automatically without any intervention procedures. Experimental numerical results indicate proposed provided sufficiently similar those obtained ...
