Fracture Mechanics Analysis of a Modified TSD Specimen

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


The Tilted Sandwich Debond (TSD) specimen has been recognized as a viable candidate for characterization of the face/core fracture resistance. Analysis, however, shows that the range of phase angles that can be realized by altering the tilt angle is quite limited. A parametric study however shows that a way to extend the mode-mixity span of the TSD specimen is to reinforce the loaded upper face with a stiff metal plate. In this way, the range of phase angles is extended to a practical range. Guidelines on selection of thicknesses of the reinforcement, and design considerations for further modifications are provided.
