Abstract

Preliminary results are presented on the formulation of a semi-analytic method to account for the effects of shear on energy release rate and mode mixity angle in a three-layer (sandwich) beam with a face/core debond. The method uses dimensional analysis, twodimensional elasticity and a finite element displacement extrapolation technique. The expressions for the shear components of the energy release rate and mode mixity phase angle are combined with results for three-layers subjected to bending-moment and axial forces to obtain solutions for general loading conditions. The accuracy of the method is verified using results for bi- and three-layers subjected to bending and she.
