Yuriechko V. Stress-strain state of porous elastomeric materials in nonlinear deformation

An object of research is a processes of deformation of structural elements made of porous materials in viscoelastic and geometrically nonlinear deformation. Subject of research – the parameters of the stress-strain state of structural elements made of porous materials in a viscoelastic and geometrically nonlinear deformation. The purpose of the research is the solution of problems of mechanics of deformable solids in three-dimensional formulation for porous materials in a non-linear deformation. Methods of research – in determining the parameters of the stress-strain state of structural elements made of porous materials was used finite element based on the moment sheme, which is a modification of the finite element method. In the development of the iterative process of solving the problem of viscoelasticity and geometrically nonlinear problem of deformation of structural elements of the porous elastomer materials modified Newton-Kantorovich method was used. The approaches to the solution of three-dimensional problems of solid mechanics for porous materials and investigated as accounting porosity affects the parameters of the stress-strain state of structures of porous elastomeric materials. Scope - engineering.
