  OBJECTIVE   A crashbox is a highly energy absorbing structure that crashes application of loads and reduces impact on other components nearby.a fully fledges crash box is highly sophisticated design but in this case we will go with rectangular channel which can through of as the most simple crashbox.  …

OBJECTIVE In this assignment, you will model spotwelds for the given assembly of parts and run a crash test similar to the one in assignment 4. Details about spotweld location is in the image below. The yellow line signifies the spotweld directions. You need to use 3-7 spotwelds along this line, in a symmetric manner,…

Objective  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 from the above figure. Use appropriate boundary conditions to simulate tensile behavior for the model and finally compare…

Head Impact Pedestrian safety simulation is a part of vehicle safety engineering.this study focus on car and pedestrian on car and pedestrian interaction.the main focus of this is to reduce the pedestrian injury in case of an accident (head,injury leg etc). usually these tests are performed in the lower velocity range…

Objective  Use 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 contain…
