Abstract
Problem Statement (Relevance). Currently, there is a growing trend to replace traditional structural materials with composite ones. High specific mechanical properties of composites contribute to designing lightweight and reliable structures. A promising scientific area is the development of composite materials that increase mechanical characteristics by improving the external structure and manufacturing technology. The manufacturing technology of Al-steel composites with wavy contact surfaces between aluminum and steel provides increased strength of the connection between the layers. To design structures from composite materials, integrated packages of finite element calculations are widely used to simulate the effect of various loads, geometric dimensions and materials of elements in each layer on stiffness of composites. Objectives. The research is aimed at studying the influence of the wave profile on the deformation of a layered composite sample. Methods Applied. Using the SIMULIA/Abaqus software suite, the authors obtained deflection curves, as well as strain and stress distributions along the Z-axis of the deformed mesh along the length of the composite sample for various deformation schemes. Originality. The authors carried out a novel simulation of the process of bending of layered composite AMg3-08sp with flat and wavy interfaces. Result. It has been established that a wavy interface of the steel-aluminum composite increased stiffness of the product. Based on the calculated data on the distribution of deformation and von Mises stresses in different layers of the composite, it has been shown that the reason for the decreased deformation in the composite with a wavy interface is the redistribution of stresses. Practical Relevance. The results of the study contribute to designing composite materials with increased stiffness.
