Question 1-1: 1-D Bar Element Method (20 marks)
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 1-2: 1-D Truss Element Method (30 marks)
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.
