Design and Implementation of Different Truss Core Laser Welded SS304 Grade stainless Steel Corrugated Core Sandwich Panel’s Optimum Response to Dynamic Force

Abstract

Sandwich panels made of corrugated core steel are a practical solution to lighten and stiffen steel structures. These panels have demonstrated very promising economic potential in a variety of applications such as automobile, marine and aircraft. The laser welded panel with different geometric parameter offers the high strength to weight ratio. The laser welding is used because it has excellent economic and operational efficacy, as well as its low weight and high strength to weight ratio. The weld width, weld misalignment, and a plate gap between the face sheets and cores are the geometric characteristics of the connection .The corrugated core sandwich panels with dual weld lines per crest are used generally. This study describes the process of designing, manufacturing, and commercialising corrugated core sandwich panels. The typical low-carbon steel grade SS304 and ferritic stainless steel grade SS305 with the plate thicknesses of 2mm, 4mm, and 6mm are utilised as test materials for corrugated cores and skin plates. This study describes the process of designing, manufacturing, and commercialising corrugated core sandwich panels. The result’s findings shows that the induced stress and corresponding deformation of both top and bottom face sheets with core is proportional to varying compressive loads and height of the core . As the core height varies, strange changes in both impact accelerations and degrees of deformation occur. The current work is Investigating and analysing the effects of geometric factors for a particular increasing load operating on the surface of the panel and comparing the experimental results with FEA and analytical result for different geometric configuration, as the results shows that the experimental, numerical ,and analytical findings are consistent.
