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 likeautomotive, aviation, aerospace, construction, and defense owing to their high specific strength, impactresistance, and lightweight. In this paper, different from the previous literature efforts, temperature-induceddeformation behaviors of polymer layer-added metallic laminates were analyzed via a finite elementapproach. As interlayer polymers, epoxy, and rubber were used separately between the metallic plates. Thesimulation results showed that as the ambient temperature increased from 20°C to 100°C fixed side of themodel reflected higher stress levels. Also, when force levels went up total deformation escalated for bothepoxy-added and rubber-added models. In addition, from the outcomes, it was obvious that polymericinterlayers had a blocking effect for excess stress concentrations on the whole design geometry and had thecapacity to reduce the total weight compared to solely metallic combinations that are vulnerable tounwanted delamination.
