Finite element modeling of thin-walled shell composite structures

Abstract

An algorithm for solving the problem of elasticity theory for composite thin-walled shell composite structures with junction lines is proposed. The SMCM software was created based on the finite element method and the developed algorithm. A test problem was solved for a composite shell structural element of the box-plate type docked with 4 other plates. A comparative analysis of the obtained results was carried out with the reference solution of the three-dimensional elasticity problem in the ANSYS software, as well as with the two-dimensional shell solution of the ANSYS software. SMCM PC allows obtaining results that are closer to a three-dimensional solution.
