Abstract

Epoxy pressure vessels with fatigue cracks in the nozzle corner were burst.1 The remains were cut into beams forK Ic measurements. With nominal stress from burst pressures, crack sizes from measurements and stress intensities fromK Ic, the shape factors were determined from the fundamental equation of fracture mechanics.
