Proposal of new damage model for thermal shock based on dynamic fracture on the brittle materials

Wavy cleavage fracture of bulk metallic glass

“…When a brittle material is subjected to a dynamic loading, it was confirmed that the dynamic strength strongly depends on the fracture time, 26,27 indicating that dynamic fracture phenomenon is not instantaneous but requires a certain time.

Simulation of damage and failure processes of thermal barrier coatings subjected to a uniaxial tensile load

“…In our simulation, a linear elastic model was used to characterize the brittle behavior of YSZ (top coat) and the maximum tensile stress was defined as the failure criterion. The failure value was measured by our research group using the uniaxial compression Brazilian test, which is generally employed to acquire the tensile strength of the brittle materials indirectly [41]. The test method details can be found in the literature [7].…”

Finite element simulation of tensile bond strength of atmospheric plasma spraying thermal barrier coatings

“…Jeong and co-workers [20] presented a modified Brazilian disk (MBD) specimen to acquire the indirect tensile strength of 'Lead Crystal Glass' material. In the present research, the MBD specimen with one small hole in the center of the specimen, shown in Fig.…”
