Week 3 - 2D meshing for sheet metal

Aim: To perform a crash test of a crash box using Ls-Dyna. Objective:  To create a rigid wall in LS-Dyna Apply initial velocity of 50 kmph to the crash box. Run the simulation and compare results of crash box having thickness 1.2 mm and 1.5 mm respectively. The unit system followed is gm-mm-ms Plot the cross-sectional…

AIM:  To Create drop test simulation using LS-DYNA OBJECTIVE: Creating the LS-DYNA simulation for drop test.  In this problem, mobile is dropped on rigid base. The colliding distance is very close and mobile hits the surface with an initial velocity. The analysis is done from the instant mobile…

  AIM:  To study about implicit and explicit method to solve engineering problems. OBJICTIVE:  As demonstrated in the PDF, F(u) = u3+9u2+4u we use this equation and solve using both Explicit and Implicit Methods with tolerance of 10-2. Explicit: As opposed to Implicit methods, explicit method is…
