Thermal Effect in Dynamic Yielding and Fracture of Metals and Alloys

Source abstract

The explanation of transition between ductile and brittle modes of fracture based on the “incubation time” concept is proposed. This approach allows us to establish relation between the influences of different loading parameters (strain-rate, temperature) on the mode of fracture. Proposed criteria give explanation to anomalous behavior of yield limit and possible high-temperature embrittlement.
