Figure 5.1 Cantilever Beam Problem Sketch ¡ ¥ £ £ ¤ ¤ £ £ ¦ ¢ Material Properties E = 30 x 106 psi υ = 0.0 Geometric Properties = 50 in d = 3 in t = 2 in Loading F = 4000 lb The PLANE82 model uses the same node numbering at the element corners as the PLANE42 model and has additional midside nodes added to all elements. Analysis Assumptions and Modeling Notes Two different solutions are obtained. The first solution uses lower order PLANE42 elements and the second solution uses higher order PLANE82 elements. The 2 inch thickness is incorporated by using the plane stress with thickness option. Poisson's ratio is set to 0.0 to agree with beam theory.
