A Comparative Finite Element Effort for Detection of the Effect of Epoxy and Rubber Interlayers on Temperature and Force Induced Stress Behavior in Metallic Laminate Composites

Abstract

Recently, metallic laminate composites have been considered attractive for lots of industries like automotive, aviation, aerospace, construction, and defense owing to their high specific strength, impact resistance, and lightweight. In this paper, different from the previous literature efforts, temperature-induced deformation behaviors of polymer layer-added metallic laminates were analyzed via a finite element approach. As interlayer polymers, epoxy, and rubber were used separately between the metallic plates. The simulation results showed that as the ambient temperature increased from 20°C to 100°C fixed side of the model reflected higher stress levels. Also, when force levels went up total deformation escalated for both epoxy-added and rubber-added models. In addition, from the outcomes, it was obvious that polymeric interlayers had a blocking effect for excess stress concentrations on the whole design geometry and had the capacity to reduce the total weight compared to solely metallic combinations that are vulnerable to unwanted delamination.
