MMD3040-N Computer Aided Analysis Assignment 2 – Tees side University Singapore.

Subject Code & Title : MMD3040-N Computer Aided Analysis
Assessment Type : Assignment 2
Non-linear analyses :
This assessment covers learning outcomes 2, 4, 6, and 8 for this module and the standard university assessment criteria for this level apply. According to certain engineering standard, a ring gasket is required to have around 0.2 mm of permanent deformation so that flange can be sealed tightly as shown in Figure 1. As an engineer, you are required to determine an appropriate pressure level to be applied on the ring gasket.

With the support of your literature research, you are required to produce 2000 words report which includes:

1.Literature research on ring gasket, which covers industrial application, material properties, failure mode etc.

2.Coverage of finite element theories on non-linear analysis for ring gasket
problem.

3.Detail explanation of the procedures on how 3-D Finite Element Analysis is carried out using NX software to solve this ring gasket problems.

4.Explain how you acquire meaningful results and justify the result reliability.

5.Describe the challenges/limitations of using finite element modelling on ring gasket problem and propose solution to address the limitations.

You are expected to perform literature research in order to support your statement. Please note that you are encouraged to use picture illustrations to support your explanations. You are required to upload your report to blackboard by 17th January 2022 end of day.
