Finite Element Analysis of Beam Specimens Used to Measure the Delamination Resistance of Composites

CODEN: JCTRER

Abstract

The energy release rates G applicable to various beam specimens used to measure the delamination resistance of composites have been calculated using finite element methods. The results have been compared with beam theory solutions, GBT . While appreciable discrepancies exist, it has been found that the differences are expressible through a nondimensional parameter, ρ, identified from orthotropy rescaling. Consequently, accurate solutions for G are presented in terms of GBT , qualified by analytical series functions containing ρ.
