Assignment 6-Frontal Crash Simulation Challenge

Aim: To understand the difference between Implicit and Explicit method with application of forward and backward euler method.   Explanation: Implicit Analysis: The time taken for each step of analysis is more. The analysis is stable even for larger time steps. Explicit analysis: The time taken for each step is less. The…

UnderBody Coating A car’s underbody is exposed to the most wear and tear caused by muddy water, potholed roads, stones and other obstacles on the road. Because it’s not in plain sight, we often do not see the damage. Under body coating is a thick resilient coating applied to the under body or chassis of an…
