Week - 2 - Explicit and Implicit Analysis

Aim: Simulation of a crash box crashing on to a rigid wall. Abstract: A crash box is an energy-absorbing structure that reduces the damage to critical and expensive parts of the car and the passengers in the event of a vehicle collision. In this simulation, we are using a simple rectangular sheet-metal box of thicknesses…

Aim To create an input deck for the cellphone drop test from the basic keyword file. Procedure A. Creating Material IDs The keyword MAT is used to define a material. For the cellphone, Aluminium was selected since most of the latest mobile phones use aluminum or Al alloys for the cellphone body. And steel properties are…

Implicit and Explicit Methods     Explicit and implicit methods are two different approaches used in numerical analysis for calculating approximate numerical solutions to time-dependent ordinary and partial differential equations.  Implicit and explicit equations: If we can represent the unknown variable…

Aim: Convert the units of given values to the required unit systems as mentioned. Procedure: Conversion of SI unit to gm/mm/ms 1. Mass      Value: 1 kg  in gm/mm/ms : 1000gm;  conversion factor: 1000 2. Length Value: 1 m in gm/mm/ms : 1000 mm;  conversion factor: 1000  3. Time…
