摘要

A design analysis of the mixed mode bending (MMB) sandwich specimen for face-core interface fracture characterization is presented. An analysis of the competing failure modes in the foam cored sandwich specimens is performed in order to achieve face-core debond fracture prior to other failure modes. The analysis facilitates selection of the appropriate geometry for the MMB sandwich specimen to promote debond failure. An experimental study is performed using MMB sandwich specimens with a H100 PVC foam core and E-glass-polyester faces. The results reveal that debond propagation is successfully achieved for the chosen geometries and mixed mode loading conditions.
