Investigation of nonlinear deformation of solid and porous elements of three-dimensional structures

Abstract

© Published under licence by IOP Publishing Ltd. In this paper, a number of test problems for deforming three-dimensional bodies, made of solid and porous materials, are solved on the basis of the method for solving nonlinear problems of the mechanics of a deformable solid body based on defining relations connecting the increments of true stresses and strains within the framework of the finite-element discretization of the computational domain. A good agreement between the calculation results and the known solutions was noted, and some detected patterns of deformation of bodies made of porous material were noted.
