CRASH BOX SIMULATION USING LS DYNA

AIMWe are currently working on developing code for the air standard Otto cycle to extract the pressure versus volume diagram and calculate the thermal efficiency of the cycle.The ideal Otto cycle is a thermodynamic cycle that describes how a spark-ignition internal combustion engine works. It consists of four…

Aim:demonstrate spherical, revolute, cylindrical, and translational joints between two rigid bodies and two deformable bodies. 2. Revolute jointTwo pairs of nodes are created for constraining, using Node edit option under Element Tools. The nodes 101, 102 are constrained to part 1 and 103,104 to part 2 respectively, using…

Objective:The aim of this study is to calculate the Mooney Rivlin and Ogden material constants and compare them using stress-strain data obtained from a Dogbone specimen tensile test with 100 percent strain.Background:Hyperelastic materials are defined as materials that can undergo more than 100% strain without experiencing…

OBJECTIVE In this challenge we have to perform a simulation of crash box it similar to car carsh. but, here instead of car and their element there is box like structure.
