Finite-element calculations of thin-walled structures of concatenated shells with different material stress–strain properties

Аннотация

The algorithm for calculating the stressed-deformed state (SDS) of thin-walled structures of concatenated shells with different material stress–strain properties on the finite-element method’s base with scalar and vector interpolation of displacement fields has been outlined. The quadrangular curvilinear finite-element with nine degrees of freedom in the node has been used as a discretization element. The SDS analysis of a thin-walled shell structure formed by a cylinder and two jointed shells of dissimilar materials has been performed.
