"Project is focused on complex investigation of damage mechanism of structural brittle matrix composites under high temperature conditions (fire, containers for nuclear waste) with using of experimental techniques and numerical simulations. Damage of structures when loaded with high temperatures on macro level is conditioned by physical and chemical changes in material. Experiments are designed with a high complexity to qualify an influence of micro and meso changes on material damage. Application for numerical simulation of temperature field in material and constitutive relations for mechanical/physical properties in dependence on temperature will be provided. It will serve as a procedure for nonlinear solvers of quasibrittle damage. Complex research on damage mechanism of concrete structures loaded with high temperatures with using of experimental and simulation techniques is essential for development of resistant materials and criterion for safe and economical design of structures."@en .
