Directions and results of research
Development of effective algorithms for simulations of deformations and destruction of complex physicomechanical structures under geometrical and physical nonlinearity at shock loading. Effective algorithms for the deformation of complex nonlinear structures at dynamical loading have been developed and tested.
Development of effective finite elements of laminated composites for the structure analysis in the case of large displacements. Effective finite elements for the structure analysis in the case of large displacements have been developed.
Investigation and optimization of algorithms to develope adaptive procedures for the analysis of spatial structures. The relevant algorithms have been developed, program modules to develope adaptive procedures for the analysis of spatial structures have been composed and compiled.
Analysis and investigation of conditions for the existence and change of dominant mechanisms of destruction in the case of combined forms of loading accounting for the determinative properties of elasto-plastic medium. Investigation of the effects of the type of the steel structure on the mechanism of destruction in the case of combined forms of deformation. It has been shown that the transition from the brittle fracture to the ductile one may be determined by the relationship between the sizes of the plasticity zones and the process of destruction. On the basis of experimental data the parameters of the macro- and microrelief of the failure surface have been estimated. The preferential mechanisms of the fracture kinetics under the joint action of the displacement and separation have been established for various types of the steel structure.
