| Title of the article | Analysis of emergency collision actions on the spatial frames |
| Abstract. | The technique of investigation of the stress-strain state of frame structures with inelastic collision effects is adduced. Analysis of the dynamic behavior of the objects is performed taking into account the geometrical and physical nonlinearity. The problem was solved by direct integration of the differential equations described the motion of the structural systems with use the Newmark method presuppositions. The finite element model is constructed for the geometry of structures in the deformed state. It takes into account the elastic-plastic material behavior. The structural damping of the Rayleigh oscillation scheme is used. An example of calculation of the spatial frame using the proposed computational process is considered. The calculations are performed with the physical nonlinearity based on the associative flow of the material. The above example of the calculation of spatial frames on extradesign Shock shows performance of this algorithm. The proposed design procedure can be used to solve the problems of identification of design basis impacts on core system. |
