Question

1) For the truss shown in Fig. 1, determine the nodal displacements and stresses in each element by using hand calculations. Let the cross-sectional area of each element, A = 6 x 10^-4 m², Elastic modulus, E = 70x10⁹ N/m², Poisson's ratio, v = 0.3. You can solve the matrix equation by using a calculator or computer. Verify your result by comparing against ANSYS solution.

2) A square simply supported 50 cm by 50 cm steel plate with thickness 3 mm has a round hole of 10 cm diameter drilled through center. The plate is uniformly loaded from the bottom surface with a pressure load of 15 kN/m². Elastic modulus is E = 210 x 10⁹ N/m² and Poisson's ratio is v = 0.33. Determine the von Mises distribution in the plate.

Answer 1

Be sure to read the question illustrated below and provide solution by showing the computation part. A square simply supported 50 cm by 50 cm steel plate by means of thickness 3 mm consists of a round hole of 10 cm diameter drilled via center. The plate is uniformly loaded from the bottom surface by means of a pressure load of 15 kN/m2. Elastic modulus is E = 210 x 109 N/m2 and Poisson's ratio is v = 0.33. Find out the von Mises distribution in the plate.
