Investigation of deformation and failure of the laminated composite Cr-V by the method of computer modeling

Abstract

The article presents a further development of the mathematical method [N. V. Shadchina et al., Probl. Prochn., No. 2, 88–91 (1990)] that makes it possible to model the processes of deformation and failure of composite materials on a personal computer. The strength characteristics of laminated materials Cr-V are calculated on the basis of the physicomechanical and structural properties and with a view to their statistical scatter and the properties of the interlay er forming during the production of the composite. It was established that when the layers are thinner, the dependences of ultimate strength and yield strength of the composite material on the mean thickness of the layers are transformed into dependences Petch—Hall-type.
