Adhesion Strength of Cordierite Bulk Coatings on Molybdenum Substrates
… because of ease in testing and availability of fracture mechanics interpretations of test data. The interfacial fracture toughness was determined from indentation load vs. crack length data by examining the residual stress and critical buckling load of the ceramic coatings. The interfacial …

Mechanochemical activation at solid interfaces
… at the molecular level and macroscopic interfacial fracture toughness at SAM-modified interfaces. Characterization and application of surface chemistry changes resulting from activation of force-sensitive mechanophore modified interfaces remains largely unexplored. In this dissertation, …

HYGROTHERMALLY-INDUCED DELAMINATION AND CRACKING IN PLASTIC IC PACKAGES
… may exist in bonded interfaces. These small interfacial defects induce very high stress concentrations around the defects leading to debonding and delamination growth. If the total stress intensity factor generated by the loading due to the hygrothermal stresses and steam pressure is higher …

Quantitative and consistent tests for interlayer adhesion in laminated glass
… drilled compression (DCDC) for determining the toughness of glass/PVB interfaces has been examined. Experiments were conducted on two different types of samples: low and high adhesion. Stress and fracture analysis was conducted using the finite element method. The numerical analysis was first …

Debonding in bi-layer material systems under moisture effect : a multiscale approach
… and the constitutive materials. In particular, interfacial delamination has been observed as a major integrity issue. In this research, a comprehensive investigation on the interfacial debonding mechanism has been conducted both computationally and experimentally using an epoxy-silica system. In …

Debond Buckling of Woven E-glass/Balsa Sandwich Composites Exposed to One-sided Heating
… core material. In order to better understand the interfacial behavior, Mode I Double Cantilever Beam (DCB) fracture tests were performed at ambient, 60 C, and 80 C to determine the influence of the decreased Mode I fracture toughness. While ambient testing showed that stable crack growth could be …
