T1 - Effect of pulse shape on spall strength
AU - Smirnov, V.I.
AU - Petrov, Yu. V.
N1 - Funding Information: The introduction of a characteristic time of fracture can help explain the effect of loading rate on the fracture of metal at a macroscopic scale, which is required in the development of techniques for testing and certification of strength properties of structural materials. This work was supported by the Russian Foundation for Basic Research (Grant No. 16-01-00638-a).

N2 - This paper analyzes the effect of the time-dependent shape of a load pulse on the spall strength of materials. Within the framework of a classical one-dimensional scheme, triangular pulses with signal rise and decay portions and with no signal rise portions considered. Calculation results for the threshold characteristics of fracture for rail steel are given. The possibility of optimization of fracture by selecting a loading time with the use of an introduced characteristic of dynamic strength (pulse fracture capacity) is demonstrated. The study is carried out using a structure–time fracture criterion.
