Abstract

Welded gusseted frame design for fatigue loading is largely not addressed in modern machine design

texts. This research intends to uncover stress solutions for critical locations on welded gusseted frames

so that such a common engineering structure can have design basis. The problem was approached

using static equilibrium relations to populate coefficients of deliberately chosen line stress functions.

The results from that analysis were used in a subsequent fracture mechanics analysis to develop the

singular stress field at a weld toe. The current research resulted in solutions for the two most critical

stress states on welded gusseted frame structures.
