Through use of the computer code BENDPAC, a number of solutions for elbows attached to straight pipes are produced. This study focuses on the stresses at the elbow-straight pipe junction. It is noted that the largest stress component is in the hoop direction for h values less than 0.5, whereas for h greater than 0.5, the axial stress dominates. Simple expressions for stress indices in both directions are given.
