On February 16, 2016 at 2 p.m. Prof. Larisa Stepanova of the Department of Mathematical Modeling in Mechanics of Samara State Aerospace University presented the report at Samara Center for Theoretical Materials Science conference hall.
Report topic was “Multiscale models of fracture processes and nonlinear deformation of cracked samples for analysis and prediction of strength and durability of construction elements during continuous operation”.
The report reviewed multiscale description models of a crack tip stress-strain state based on the methods of damage mechanics, asymptotic methods of perturbation theory and finite element analysis.
Prof. Stepanova discussed the issues of theoretical, computer and simulation modeling, numerical and asymptotic solution of problems of nonlinear deformation and damage of materials under multiaxial stress considering damage accumulation processes in solids under plastic flow, creep and/or fatigue conditions.
Prof. Stepanova proved the necessity of creation and development of multilevel, multiscale models (micro-, meso- and macrolevels) for damage accumulation in solids and formulation of inelastic materials’ damage criteria considering damage processes of materials under deformation.
