Question 1: 1-D Bar Element Method
Considering an assembly of two bar elements made of different materials as shown in Fig. 1-1, you are required to:
1) Create a two bar-element model to determine nodal displacements, element stresses, and reaction force; and
2) Use ANSYS to conduct an FEA for validation using the same FE model.
Question 2: 1-D Truss Element Method
The finite element model of a plane truss shown in Fig. 1-2 is composed of 4 members, all having a round cross section with a diameter of 20 + 0.Q mm and the modulus of elasticity E = 210 GPa. You are required to: 1) compute the nodal displacements in the global coordinate system for the loads shown as well as all the reactions at each support; and 2) use ANSYS to conduct an FEA for validation using the same FE model.
Question 3: 1-D Frame Element Method
For the two-frame structure subjected to a uniformly-distributed loading depicted below in Fig. 1-3, you are allowed to use only two frame elements to conduct an FEA. The two frame members are made of square beams material properties and rectangular cross-section as well as the same height. You are required to:
a) Determine the unknown displacements at the point B, the reaction forces at points A and C and the maximum stresses in the frame and b) apply ANSYS to validate the results obtained from a).
Note - Use Q = 849. Problems need to be solved manually (hand calculated) and Ansys for FEA validation. Use excel for hand calculation results. Which is stated in the word file. Word limit such as 2000-3000 words.
