Recertification of Pressure Vessels and Pressure Systems
(The American Society of Mechanical Engineers (ASME), 1986)There are strong economic and safety incentives to recertify pressure vessels, pressure components, and piping for continued service after their nominal original design life has been exhausted. ... -
Ductile Fracture Micromechanisms in A508 CL3 Structural Steel
(The American Society of Mechanical Engineers (ASME), 1986)Studies of the critical void volumes ahead of cracks at the initiation of fracture at 100° C in the ductile regime show that the void volume has a maximum at a distance of about one ... -
Increased Allowable Stresses for Earthquake and Wind Loads in Section VIII, Division 1
(The American Society of Mechanical Engineers (ASME), 1986)There has been a need for some time to provide rules for allowable stresses for short-time and infrequent loading such as earthquake and wind loads in Section VIII, Division 1 of the Boiler ... -
J-Integral and Tearing Modulus Estimates for Circumferentially Cracked Pipes in Torsion
