ANALYTICAL AND NUMERICAL ANALYSIS OF SANDWICH COMPOSITE MATERIALS WITH DIFFERENT CORE STRUCTURES

Sandwich panels consists of thin, stiff face plates which are separated by thick core material. The face plates carry the bending loads and the core is carries longitudinal loads. The face plates and core are choosen from metals such as stainless steel or aluminium alloy or copper but the core can also possess various sandwich structures such as O-core, I-core, Web Core, I-Core, etc. This construction has often used in lightweight applications such as aircrafts, marine applications and wind turbine blades. Sandwiched panels have advanced high stiffness and strength to weight ratio. In this current project, comparison is drawn among different sandwich structures by numerical analysis in ANSYS software and analytical method. Based on the results obtained from both analytical and numerical analysis best suited structure is suggested for replacement of honeycomb structure.
