Balanced Energy Dissipation at Propagating Crack Tip in Quasi-Brittle Materials? - Analysis via Soft-Computing Methods

Abstract:

Analysis on the aspects of the energy dissipation in the case of quasi-brittle fracture is presented. Dissipation both via cohesive forces at the crack faces and the one taking place within the volume of the fracture process zone is considered. Tools from the field of soft computing techniques are employed. The analysis is conducted on results from extensive experimental campaign.
