Objective:  To perform the tension and torsion test on the specimen provided .  For the tension test, displace one end of the specimen to 18mm while keeping the other fixed. You will need to find out the total deformation, equivalent stress and temperature of the specimen and attach appropriate images to show…

OBJECTIVE:    To perform a transient structural analysis on a worm gear assembly. For the challenge, you have to rotate the worm and get results for Equivalent stress, Equivalent elastic strain and the total deformation in the model   Case setup and Execution : 1. In Workbench , select transient…

Objective:  To perform a transient structural analysis on a double universal joint with a spring using three different materials: Structural Steel, Stainless Steel and Titanium alloy(They can all be found in the General Materials section) The three materials must be used on the joint with the springs alone. Use a…

Objective:  To perform a transient analysis on a piston and cam mechanism model that has been provided. Need to run analysis for 3 cases: Case 1: Frictionless contact Case 2: Frictional with 0.1 Case 2: Frictional with 0.2 Find out the Equivalent Stress, Directional Deformation and Equivalent Elastic Strain and…

OBJECTIVE :  Perform the analysis to simulate a sphere pressing on a plate. Use Structural steel for both sphere and plate but the material of the plate must be Non Linear. Press the sphere onto plate 4mm downwards and retract it. The plastic deformation must be captured by you   CASE SETUP AND…

OBJECTIVE :    To simulate the rolling operation on a workpiece made of copper. The model will be provided to you. Increase the length of the workpiece by 60mm and decrease its size on both sides by 8mm. Run the simulation for 14 steps and you can give small but random values( similar to the ones mentioned in…

OBJECTIVE : Sheet metal bending is to be performed for 3 different materials mentioned below. Variation of certain settings is also to be performed and your conclusions are to be added to the report Run the analysis for the material : Case 1:Aluminium Alloy 1199( mentioned in the course video),Copper Alloy NL and Magnesium…

OBJECTIVE :  Simulate three different types of welding using three different weld materials Weld Material used: Case 1.  Stainless Steel: In this case, the material of the plates must also be the same. Use Stainless steel for both weldments and plates. No need to add flux to the weldments. Case 2. Aluminium Alloy:The…

OBJECTIVE :  Perform a static structural analysis on the Railwheel and Track setup and Case 1: Multiply the bearing load by 5 times and compare the results with the load of 100000 N (As done in week 2 video). Compare the Total Deformation, Equivalent stress and the life under both the loads Case 2: Implement a User defined…

OBJECTIVE :  1)Write a few words on what a grid dependency test is and its use. 2)Perform a grid dependency test for the Bevel gear simulation for mesh sizes of 6,5 and 4 mm 3) Solve for Von-Mises stress, Equivalent elastic strain and Total Deformation using the previously mentioned mesh sizes. 4) Present your findings…
