Question

Consider a three rod system as show in figure below. The end A of the rod is fixed for all degrees of freedom. The end B is assigned a tensile force. Approximate the rod system as a 1-Dimensional (1-D) model in Finite Element Analysis (FEA). Use a 3-element 4-node model, one element for each rod. Write a computer program (Matlab C++) to find the displacements of the nodes. (20) Analyze the rod system as a 3-D model in ANSYS ABAQUS. with the same similar number of elements as in 1.1. Find the nodal displacement contour plot. (10) Compare the nodal displacement results obtained using ANSYS .ABAQUS with the 1-D approximation found in 1.1.
