Failure criterion for composite structure with an open-hole or bolted joint using characteristic volume approach

Abstract : We propose a non-local failure criterion to predict the failure of composite laminated structures submitted to local stress concentration. The twill glass/polyamide 6 composite specimens with an open-hole as well as a bolted joint have been investigated. Material behavior was modeled using Hill’s yield criterion to describe its anisotropic non-linearity. To determine a structure failure, based on the classical characteristic distance approach, the proposed method predicts the structure failure using the characteristic volume identified by experimental testing and numerical simulations. The average values of failure criteria indices over this characteristic volume were used to determine the failure. The damage initiations were predicted and showed a good agreement with the experimental results.
