Stress-Strain State of Elastoplastic Rotational Shells Under Dynamic and Static Loads

The paper presents the analysis of stress-strain state of axisymmetric elastoplastic rotational shells under the dynamic and static loads. Under the intensive loading, the deformation processes occur with the manifestation of the physical and geometric nonlinearity. Therefore, the task implementation is based on the use of numerical methods. The problem approach is based on the systems analysis, which implies the creation of several models of different complexity and implementation algorithms rather than one model for one structure. A comparison of the obtained results allows estimating the limits of applicability and accuracy of the different models and developing the efficient analysis of the stress-strain state.
