On the threshold force pulses for spall fracture of materials
V. I. Smirnov Petersburg State University of Means of Communication, St. Petersburg, 198103
Abstract:
Spall fracture is considered using the classical one-dimensional model. Results of the analysis are used to predict the dynamic strength properties of some structural materials, in particular, rail steels. The dependence of the time of fracture of the material on the threshold amplitude and time of loading is obtained. A model for the comparative estimation of the dynamic strength of materials is proposed, and corresponding diagrams are constructed. It is shown that the fracture process can be optimized by choosing the duration of loading of the material.
Keywords:
spall, time dependence of strength, threshold load pulse, structure-time criterion.
