Computational scheme of evaluating strain-stress state of piecewisehomogeneous three-dimensional elastic environment based on indirect method of boundary elements

Computational scheme of evaluating strain-stress state of piecewisehomogeneous three-dimensional elastic environment based on indirect method of boundary elements

Finite-element techniques in geomechanic calculations to assess strain-stress state in rock have shown insufficient flexibility towards varying geometry of computational schemes and necessity to set a large number of the unknown in solving space problems. Numeric calculation of stress intensity fact...
