Mechanics of Composite Materials Aims and scope

Abstract

The results of FEM investigation of the triaxial stress state in multilayer structural elements subjected to axial and bending loads are presented. The distribution regularities of the stiffness and stresses or strains depending on the geometric and mechanical characteristics of layers and their position in the cross section of beams and bars are examined. The optimization of these elements is carried out using the dependences of the Bareisis—Paulauskas method and the “Optim-98” computer program created by the present authors. As the optimization criteria, the strength, stiffness, mass, and cost of the structural elements are considered.
