CHAP 6 Finite Elements for Plane Solids 305 2. Solve Example 6.2 using one of finite element programs in Appendix. Solution: We will solve the problem using MATLAB Toolbox in Appendix D. The program list is shown below: Nodal Displacements: 0 0 -0.0021 -0.0445 0.0189 -0.0273 0 0 Element strains: et1 = -0.0013 0.0017 -0.0032 et2 = 0.0019 0 -0.0027 Element stresses: es1 = 1.0e+004 *[-2.4709 4.4406 -3.7063] es2 = 1.0e+004 *[ 6.2354 1.8706 -3.1469] The figure below shows the undeformed and deformed shapes of the elements. The deformation is magnified by 50. Edof=[ 1 1 2 3 4 5 6; 2 1 2 5 6 7 8]; ex1 = [0 10 10]; ey1 = [0 5 15];
