Chapter 2, Problem 23E

A bar shown in the figure is modeled using three equal-length bar elements. The total length of the bar is L T = 1.5 m , and the radius of the circular cross section is r = 0. 1 m . When Young’s modulus E = 2 0 7 GPa , and distributed load q = 1 , 000  N / m , calculate displacement and stress using a commercial finite element analysis program. Compare your finite element solution with the exact solution. Provide X Y graphs of displacement and stress with respect to bar length. Explain why the finite element solutions are different from the exact solutions.
