Ahmad's superparametric thick shell element with reduced integration, a transition element type having variable degrees‐of‐freedom per node and a three‐dimensional incompatible element have been used to calculate the stress distribution at the intersection region of T‐ and Y‐joint connections. To minimize the numerical effort, a transfinite blending function interpolation approach has been applied for the automatic mesh generation and the resulting system of linear equations has been solved using the front width method. Comparison of the computed solutions with some very carefully conducted experimental results has shown very good agreement.
