Numerical Analysis of Composite Sinusoidal Honeycomb Structures by using FEM

Many industries use honeycomb composites extensively, including the aerospace, automotive, furniture, packaging, and logistic sectors. A specific type of composite material known as a sandwich is created by joining two stiff but thin skins to lightweight dense core. The strong bending stiffness overall low density are made possible core material's larger thickness despite its typical strength. Sandwich panel's strength influenced size, chosen for faceplates, cells inside. This study investigates critical buckling stresses numerically different densities materials panels. In this investigation, faceplate constant while varies. It can be observed that when increases, so do specimens Analytical investigations on panels used examine behavior sinusoidal hexagonal under impact loads. LS-DYNA was analysis, HYPER-MESH modeling.
