Experimental And Numerical Studies On Various Section Geometries For Inward Inversion

Abstract -The inward inversion is one of the large deformations phenomenon in which the material deform inside the geometry. This phenomenon has been of great interest for its constant force displacement graph of deformation. The energy absorption through inward inversion can be of great use for devising the apparatus to absorb energy for impact or crash. The inward inversion to different shell section was planned to study force displacement graph in details. The energy absorption by different sections was compared. Analytical approach was adopted to simulate the experiment. The gained confidence in simulation was carry forward for generating more sections and for parametric study. The better shape of energy absorption could be suggested through this paper.
