Abstract
The paper studies the influence of a gypsum material composition on the characteristic of formation and extension of tensile fractures in the zones of tensile stress concentrations in gypsum samples under compression. The experimental results are compared with the data of on a limiting pressure calculated by the traditional and gradient failure criteria. The parameters of the gradient criterion for the studied materials are determined.
