Film Substrate

The fracture behavior of a brittle thin film on an elastic substrate under residual stress and uniaxial tensile loading is investigated. It is assumed that the residual stress in the thin film is not large enough to cause the thin film to fracture. Using a mechanical model presented in this work, the analytical solutions for the distribution laws of the tensile stress developed in the thin film, the shear stress developed along the interface and the relationship between the crack density of the thin film and the applied strain of the substrate can be obtained. The results presented in this work can provide a new analytic solution to the interfacial shear stress for characterizing the interfacial shear strength of the thin film/substrate system when the uniaxial tensile test is adopted to evaluate the mechanical properties of the thin film/substrate system.

Simulation Results

This article studies the fracture behavior of compact tension specimens under tensile loading. The test - numerical hybrid method is used to explore the effect of the location of the loading hole. And the size effect is also considered to analysis the reason of fracture behavior .The initial load for numerical simulation is based on the experimental data. In that case, the numerical simulation results can be used to study the effect of the location of the loading hole and also the size effect to the specimens.

Fracture Features

This work investigates the correlation between TiN inclusions and microstructural properties of HARDOX 450 steel using optical microscopy (OM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and electron backscattered diffractometer (EBSD) methods. Some amount of microsized TiN inclusions were formed in the temperature range of the solid–liquid zone; however, they exhibited fracture features of deep dimples rather than a cleavage plane, which is closely related to the ability of the microstructure to arrest cracks. Upon tensile loading, a single microcrack first appeared inside the microsized TiN inclusions, and then, multiple microcracks formed, parts of which widened in the direction of tensile stress. A schematic mechanism map was plotted to reveal the propagation behavior and fracture mechanism of the microcracks in the TiN inclusions.
