Thermal Stress Crack Stability and Propagation in Severe Thermal Environmentsts so severe that initiation cannot be avoided. It is based on a mechanical model consisting of a rigidly constrained, uniformly cooled thin flat plate with a uniform distribution of microcracks; results are qualitatively similar to those obtained for a three-dimensional body with penny-shaped crack

Optimum Properties of Zirconia Ceramics for High Performance Storage Heatersir Force, Heat transfer, aerodynamic heating and propulsion problems associated with re-entry and hypersonic flight within the atmosphere have led to the use of ceramic storage heaters for the source of high temperature air in hypersonic “blow down” wind tunnels. Described are: (1) typical operating

Thermal-Shock-Resistant Materialse severity of this thermal environment exceeds that for which it is possible to prevent crack nucleation; therefore, the design of thermal-shock-resistant materials is based on the concept of preventing crack propagation. More explicitly, composite materials with either carbide or oxide matrices wer

Thermal Shock Resistant Zirconia Nozzles for Continuous Copper Castingnd satisfactorily tested in the operating environment. The zirconia has an optimized stabilizer content in terms of free thermal expansion characteristics and high temperature tensile strength. The optimization is achieved through control of composition, microstructure, and crystallographic transfor

Fracture Mechanisms of Very Strong Solidsd as a purely elastic process. This concept requires reexamination in terms of the relative ease of an atomic shear movement and of an atomic pulling-apart at a crack tip. Theoretical treatments of this problem are considered. Truly brittle fracture emerges as a process that is probably quite rare.
