Week - 3 Drop test Challenge

for<gtr>

Question:

In this assignment, we provide you with a file having just nodes and elements of two parts, a simplified cellphone and a plate mimicking ground.

You need to create a complete simulation file from this to perform a drop test. *INITIAL_VELOCITY card is to be used to give velocity specifications for the cellphone.

We are not interested in how the phone travels from your hand to the plate, but only the period when the impact happens and a few milliseconds after that. Therefore, we will keep the two parts very close and provide an appropriate magnitude of velocity.

The orientation of the cellphone is also important and there are specific guidelines on how to orient the products but for this assignment, we will ignore that.

Based on what you have learned till now, use your judgment, manuals, and the previous simulations that are shown to create a complete input file for a drop test.

The objective of this assignment is not to get a correct simulation but to get a feel of creating an input deck from scratch

A note about providing meshed file:

A typical large engineering firm will have three distinct departments handling simulation work. The first two departments will handle CAD modeling and meshing. The third group will be specialists for different stimulation jobs such as static, dynamic, and thermal. These specialists will not be working on meshing much unless they need to modify it for a specific purpose. We will cover some meshing guidelines later but otherwise, we will concentrate on how to use LS-DYNA and debug
