Question
A pressurized container of dimensions 2x2x1m3 is rigidly enclosed within a truss-based containment structure as shown in Fig CW1-Q1. The internal pressure inside the container is: Pi = 6kPa. The trusses are made up of cylindrical steel bars of diameter 20 mm. The containment structure is rigidly fixed at the corner nodes. Assume the steel material has a Young's Modulus of 210 GPa and Poisson Ratio, v = 0.33.

Question 1. Use MATFESolver to set up the numerical investigation to determine the maximum displacement experienced within the structure for the above loading case. Show your deformed profile assuming a scale Multiplier, of your choice.
Question 2. Create the same structure in ABAQUS FE Solver. Show the contour plots for the displacements in the model. Compare predictions from MATFESolver and ABAQUS and comment on similarity or differences between the two predictions.
Question 3. This initial result suggests an over-design of the containment structure with quite a lot of redundant trusses (i.e., zero internal stresses). Identify these bars and remove them from the structure and re-run the simulation to assess if they are truly redundant. Comment on your observation, in comparison with the ABAQUS model.
I. Use MATFESolver to determine the deformed profile under the new load conditions. Use a scale Multiplier, of your choice for the simulation.
II. Determine the maximum displacement in the structure under these new load conditions.
Question 4. A radical re-design of the original structure and loading of Qu (1) was proposed which involved replacing the cylindrical bars with hollow trusses of inner and outer diameters of 15 mm and 20 mm, respectively.
a. Based on the proposed re-design, determine the maximum displacement experienced by the structure due to the original load of Qu (1).
b. Assuming all the bars are replaced by square cross-section bars of dimensions 5x5 mm, determine the maximum displacement of the structure.
