Question

Given that E = 16,000 ksi, A = 6 in². Develop a finite-element model in ANSYS™ using top-down modeling in the following steps. Show screen captures of your work. Make

sure you use a consistent set of units. (a) Create model geometry using the geometry for key points and lines indicated in the figure above. Present a screen capture of your model. (b) Select an element type and justify your choice? Mesh the model such that is only one-element per line. (c) Show a screen-capture of your meshed model with the applied loads and boundary conditions. (d) Show a screen capture of your material properties and real constants (e) Using the ANSYS™™ Post-processor, determine reaction forces? Show the output from ANSYSTM. (f) Determine the nodal deflections for all the nodes? Create an output table with the nodal deflection values. (g) Determine the axial-stresses in all the members? Create an output table with the axial stress values. (a) Calculate the reaction forces? (b) Calculate the stress in element 1?
