Fracture of elastic-brittle bodies under combined action of heat and mechanical loading

摘要

For the first time by calculated andexperimental way the thermal strength of diskspecimens is investigated at combined thermal andforce loading. It is shown that at cooling of a lateralsurface of specimen, loading the bending stresses bymagnitude of 20% from a level of maximum thermalstresses suffices for full specimen fragmentation.The path of avalanche crack propagation to specimenedge bends around the zone of compression and almostperpendicular to initial direction of the crack.
