COMPUTATION OF ELASTIC-PLASTIC STRUCTURES OSCILLATIONS

In this article the algorithm of calculation of elastic-plastic shells oscillations with application of the deformation plasticity theory taking into account the material compressibility is developed. The suggested technique assumes that in any specific time all the shell elements including elements located on one normal to medial surface, were in the elastic-plastic state corresponding to their stress-deformed status. The calculation results of oscillations and dynamic buckling of shells are given.
