【 摘 要 】

Two problems are solved in the paper: on ultimate loads in the initial stage of indentation of an absolutely rigid smooth wedge into a layer of an initially anisotropic plastic medium and in the final stage when the tool penetrates through the layer. The problems are solved with Chanyshev's constitutive relations of plasticity of the initially anisotropic medium based on use of the eigen elasticity tensors.
