This fracture mechanics-based method assesses which joints in the structure are most critically loaded. Adhesive bonds are modeled with beam elements and grid point forces are used to determine line forces and moments at the edge of the glued flange.

Approximate calculations of the strain energy release rate (the equivalent J-integral) can be made at the edge of the adhesive and, by comparison to the crack growth threshold, a safety factor (design reserve factor) may also be calculated.
