Comparison of Stress Distributions in a Simple Cast Tubular Joint Using 3-D Finite Element, Photoelastic and Strain Gage Techniques

Combined strip and rosette gage measurements and results from three-dimensional, finite element calculations are in excellent agreement with frozen stress photoelastic results for an efficient shape of cast-steel node under axial, brace loading. Three different meshes showed that two layers of elements through the thickness are needed.
