Metallic shell parametric study for crush behavior

Abstract

The shell structures are the choice for structural application due to their weight to cost ratio. They arewidely used in energy absorption in case of crash and impact events. The shells are widely used inautomotives, nose cone of planes, war heads etc. The response of this shell structure are quite complexfor loadings. The response depends on the geometry of the shell . This geometry could be a combinationof many basics shape. The study was planned on basic shape like cylinder, combined geometry ofcylinder and frusta and on geometry with special features. The force displacement graphs were discussedin details. The energy absorption capacities of the geometries were discussed. The analytical approachwas also used to simulate the experiment.
