Description of the problem
To examine the accuracy of the calculation of Finite elements-method and the convergence characteristics of the stiffness matrix, the maximum values of deflection w, moments mx, my and mxy of a simply supported rectangular slab are obtained at different nets of finite elements. The slab carries a uniform distributed load of p = 100 [kN/m2] as shown in Figure 28. The Young's modulus of the slab material is Eb = 1.2×10 [kN/m] and Poisson's ratio is νb = 0 [-]. The slab thickness is d = 0.1 [m].
