objective  to calculate mooney rivlin and ogdens material constants and compare both using stress-strain data from a dogbone specimen tensile test with 100 percent strain. procedure 1. the given engineering stress-strain values are tabulated in excel and the values are plotted as shown in below. 2. the given godbone…

objective  to model a material using raw data and validate the same for a dog bone specimen    Given material curve    procedure  1.using data digitizer the stress and strain data is obtained in the form of an execl workbook with stress unit ksi and stain %. 2. the stress is converted to kg…

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…

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  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…

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   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  To perform drop test analysis on the given meshed model .by providing a appropriated velocity and boundary conditions using ls dyna software and conclude the result.  GEOMETRY STUDY AND PROCEDURE . Material creation. section creation. defining boundary conditions and specifying the initial…

1. Write a detailed report about Implicit and explicit methods.  In most structural problems, the nonlinear equations fall into 3 categories: Material Nonlinearity: Where deformations and strains are large Geometric Nonlinearity: Where strains are small, but rotations are large  Boundary Nonlinearity: Due…

 OBJECTIVE to perfrom the side crash analysis of the neon biw model on the rigid pole and get the output result intrusions at B-pilllar hinge, fuel tank and peak velocity at the inner node of the door and sectional force on the cross -section. NEON SIDE CRASH -BIW Check unit system and either follow [Mg mm s] or [Kg…

OBJECTIVE   To simulate the frontal crash analysis of neon biw is by creating a rigid wall infront of the bumper to impact .the distributed mass of 700kgs is created to move the COG of model at the middle and near to drivers area .finally the  simulation is pre-processed using hypermesh ,then run using RADIOSS …

OBJECTIVE  Create the mesh for bumper assembly,mesh size should be 6mm.  Run the crash tube model as it is. Change the Inacti=6 and run. Create the type 11 contact and run. Remove both notches  and remove boundary condition on rigid body node then run. Create a new notch in the middle ,select the whole section…
