EXCERCISE PROBLEMS
1. Compute the assembled 8 × 8 matrix for the spring assemblage shown in the figure.
2. Analyse the composite axial bar shown in the figure when
- F2 = 10 kN;
- F2 = 10 kN and U4 = 2 mm; and
- F2 = 10 kN and U1 = U4 = 2 mm. Consider Est = 200 GPa, Ast = 2 × 10−2 m2; Eal = 70 GPa, Aal = 1 × 10−2 m2
3. Analyse the plane truss structure shown in the figure using finite element method.Let E = 200 GPa, A = 1 × 10−2 m2 and L = 1 m.
4. Analyse the plane truss shown in the figure by using finite element method.Let E = ...
