Biot’s parameter is included in the formula for calculating effective stresses and should be taken into account when assessing the stress-strain state of a water-saturated rock mass. A method for calculating Biot’s tensor parameter based on asymp

Modeling a pneumatic tire with a strong change in shape causes the problem of choosing an adequate model for rubber-cord plies. Generally, the classical method of asymptotic homogenization is not suitable due to physical and geometrical nonlinearity

Methods of composite mechanics were used to evaluate the effective elastic moduli and Biot’s parameter of porous media. Natural composites — dolomites and hyaloclastites — were considered as examples, which were also examined experimentally. Th

The homogenization of static elasticity equations describing the stress strain state of fluid-saturated porous medium is considered. In this paper, the homogenization method is used to determine the pore pressure transfer tensor, which (a coefficient

An approach is proposed to determine the effective relative expansion coefficient of a porous medium filled with water during its freezing. This approach is based on an asymptotic homogenization method. An explicit formula is derived to find the expa

A theoretical approach to defining the pore-pressure elastic modulus and the tensor of the pore-pressure transfer on a rock matrix by asymptotic averaging is proposed. The approach is tested on model and real geological specimens by using the finite-

The problems of underground fluid mechanics devoted to the motion of fluids in pores and cracks of rocks are of interest due to the exploitation of oil fields as well as in the case of long-term water pumping to provide the urban population with wate

The land subsidence near an oil-producing region is simulated. The elastic filtration regime (the Terzaghi model) is used. The numerical simulation is performed by the discretization of the boundary value problem in spatial variables with the aid of
