OBJECTIVE : Using the diagram of the true stress-strain curve of graphite iron casting. Two curves are there for different material structures. I need to pick any one of them and use the data to create either a MAT_024 or MAT_018 material model and then validate it.  Theory : Materials modelling is very necessary…

OBJECTIVE :  To use the mass scaling to reduce the runtime of a model and ensure the stability of mass scaling. The hard limit on mass scaling is 8% and stability should be completely intact. This means that two simulations, one with mass scaling and one without should behave exactly the same way. The submission should…

Aim:   In this project, a children's head form model is provided. We are supposed to replicate a scenario where this head form will impact on a car bonnet. The bonnet should be considered as a rigid wall for the 1st case and while using the meshed hood model a elasto-plastic material card has to be used. From the…

AIM : Create a block of 10mmx10mmx10mm dimension with 10 elements for each direction and use the material card attached (Ogden_Material.k) that is representative of the material properties. Use appropriate boundary conditions to simulate tensile behavior for the model and finally compare the results from your simulation…

Aim : In this assignment, we need to model spotwelds for the given assembly of parts and run a crash test. Details about spotweld location is in the image below.

AIM :In this assignment, we need to simulate a crash test for a crash box for which mesh is given. A crash box is a highly energy absorbing structure that crashes on application of loads and reduces impact on other components nearby. A full-fledges crashbox is a highly sophisticated design but in this case we will go with…

AIM : to perform drop test simulation of mobile phone on the rigid floor. Procedure : As the given model consists meshed model so no need to mesh so just carrying out the analysis is enough. So before carrying out the analysis we need to prepare the deck so the part, material, section, initial velocity, Boundary, Contact,…

Aim : To solve the given problem using both explicit and implicit method and plotting the results. It shows an example nonlinear static problem. In both cases an incremental load control scheme is used. Consider the case of a simple bar in tension. Suppose that the force in the bar is a nonlinear function of the displacement.…
