Calculation of energy release rate for adhesive composite/metal joints under mode-I loading considering effect of the non-uniformity

A simplified plate model based on Kirchhoff theory is proposed for the un-symmetric double cantilever specimens (DCB) under pure mode-I loading. Based on the results of three-dimension finite element analysis, the calculation for non-uniformity coefficients βB of composite/metal DCB specimen can be converted to determination of non-uniformity coefficients βG, βS for two symmetric DCB specimens composed of composite laminates and metal plate,...
