Main Assignment 2
Programme Name:Bachelor of Engineering Technology (Honours) Mechanical Engineering (Top-up)
Module Title: Computer Aided Analysis (BEng Tech)
Module Code: MMD3040-N
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 0.2mm of permanent deformation so that flange can be sealed tightly as shown in Figure 1. As an engineer, you are required to determine the appropriate pressure level to be applied on the ring gasket. The geometry of the gasket can be modelled as octagonal toroidal as shown in Figures 2(a) and 2(b). It is noted that the side of the octagon is of s and the diameter is of 860mm.
