SED302: CAE and FEA Process- Portfolio Assignment

Internal Code: MAS273

Portfolio Assignment:

Question 1: 1.What is the maximum stress in the beam of the current design? 2.Modify the cross Section of the beam, reducing the volume of material required, such that asafety factor of 1.2 is guaranteed(assuming the same yield strength 250MPa). Show your design change and the results for the deflection and safety factor of your altered design. Question 2: Run the Cantilever Beam problem analysis given in the first seminar using (i) beam elements and (ii) solid elements (without modifying the original cross-section of the beam). And answer the following questions: 1.What is the maximum deflection at the free end of the beam in the two analysis? a.What could be reasons for the difference? 2.What is the maximum stress in each model? a.What could be the reasons for the difference? 3.For a problem like this, which element makes more sense to use and why? Question 3: 1.Collate, in a tabulated format, the comparison between the solid element model and shell element model
