Abstract : Test specimens in the form of cylindrical pressure vessels were deep drawn from AISI 4130 steel and heat treated to an average uniaxial yield strength (0.2 per cent offset) of 207 ksi. Each vessel was provided with an initial surface crack consisting of a mechanically-produced slot, terminating at each end in a fatigue-induced, hairline-type crack. Strain gages mounted at both ends of the crack provided a measure of the displacement at these locations during the development of internal pressures culminating in bursting. (Author)
