Q & A of Week 1 contents 1. If the unit of length is m, unit of force is N, unit of time is s in an FE model, what is the unit of Young’s modulus? mass? density? If a steel has a density of 7800 kg/m3, what is the input value of the density in the FE Abaqus model? 2. What is the difference between a truss element and a beam element? 3. What are the limitations of the work-energy method to calculate the displacement of a truss structure? 4. What are the meaning of the Abaqus element codes T2D2; T3D2; B21; B31 5. Why should we only use one element for one truss member in an FEA of a truss structure?

Week 2 contents 1. Displacement, strain and stress
