Abstract

An extensive parametric analysis shows that the modified Tilted Sandwich Debond (TSD) specimen provides a methodology for characterization of the face/core fracture resistance over a range of mode-mixities. A pilot experimental mixed mode characterization of the fracture toughness of sandwich specimens, with composite faces and various PVC foam cores spanning a range of phase angles, has been achieved by specific steel bar reinforcements and testing over a range of tilt angles.
