Table 1 Determine the deflections at the centre of rectangular plates (1000 mm x 2000 mm) under uniformly distributed load (UDL) q = 1.0 N/mm² for different boundary conditions as shown in figure below. Take E = 200 GPa and v = 0.3. Obtain the deformation shape which indicates the predicted value of the deflection at the centre of the plate for different boundary conditions. Compare the predicted deflections from ABAQUS with analytical results given in Table 2 for two cases detailed in Table 1: (a) thick plates with thickness h =200.0 mm (b) thin plates with thickness h = 1.0 mm b=2000 mm Edge 1 Edge 4 a=1000 mm Edge 3 Edge 2 Write the deflection in empty cell for different boundary conditions.
