|Summary||The tilted sandwich debond (TSD) specimen has been introduced to characterize debonding of a sandwich structure. An elastic foundation model for specimen is developed that may be utilized for data reduction of face/core debond toughness and specimen design. Design considerations will be discussed in this paper, and the applicability of the analysis will be examined for sandwiches consisting of E-glass/vinylester face sheets bonded to H100 and H200 cores.
||Keywords|| TSD specimen, debond fracture, elastic foundation, interfacial crack, sandwich panel, glass/vinylester face sheets, PVC core, toughness.
