Features of composite materials with viscoelastic polymer layers numerical simulation

Authors have analyzed the existing configurations of composite materials, which help to modeling the contact between two materials surfaces with different physical and mechanical parameters. This is the main purpose of the research. Researchers have considered the possibilities of studying the layered materials mechanical properties and strength characteristics by using finite element analysis. It was based on the creation of numerical models, which reproduce the objects of the studied physical object and phenomenon. There are the features in determining the stress-strain state of material models by using a numerical experiment in a modern software package, which allows the determination process of many physical and mechanical parameters without physical experimental tests. Authors presented the method of the contact layer, which could give the possibility of predicting the layered composites behavior as accurately as possible and numerically reproducing the stress-strain state rate. There are the methods for finite element modeling of contact between two different materials that make a layered composite in this paper. Researchers also describe approaches to contact modeling using the LS-DYNA and LIRA-SAPR numerical simulation software packages in this article. It has been considered the several scenarios for modeling adhesive contact in order to find the most optimal one, which could allow analysis of layered composites structural elements. The obtained results of the analysis demonstrate the potential in modeling the contact layer, which include the physical parameters of the adhesive interaction. They also provide a comparative assessment of the existing programs configurations, which is important for the strength calculations development. This work could be interested to specialists, designers and engineers in the field of modeling the physical and mechanical composite structure materials characteristics.
