Finite elements and solution methods of nonlinear equations in combination with high-performance computing technology make it possible to perform analysis of large and complex systems taking into account nonlinear deformation of the material. However, the applicable standard methods of calculation are presented on the cross-section of the element. To fill this gap, the authors propose a method of modeling of concrete finite element, based on existing norms and state standards. The authors propose to take into account the destruction of elements in the treatment process. In this case, the nodal reaction of destroyed elements are applied as external load. Modeling of damage to concrete cube press. A comparison of different theories of strength for the calculation of the equivalent stress. As a skeletal chart selected state diagram with explicit separation of plastic and elastic deformations. Diagrams of deformation of the cross section of the cube in the process of loading the Deformation model. Identified areas of damage to concrete cube when reaching the ultimate strain. Defined theory of strength and the model that best reflects actual stress - deformation of concrete during the treatment process. The proposed method can be applied for numerical analysis of reinforced concrete structures by finite element method.
