Abstract: An analytical method is presented for calculating real contact ratios for plastic/plastic or plastic/steel spur gear pairs. A comparison is made with published experimental data and the method ...

Abstract: An integral is developed for calculating opening mode stress intensity factor at any point on the front of an irregular planar crack embedded in an infinite solid and subjected to an arbitrary ...

Abstract: Mode I weight functions were derived for the deepest and surface points of an external radial-longitudinal semi-elliptical surface crack in a thick-walled cylinder with the ratio of the internal ...

Abstract: The deformation of a Morrison seal, used successfully at 56,000 lb/in.2 pressure, is determined using finite element techniques. This analysis is used as the basis for a discussion of the ...

Abstract: Fatigue cracks in shot peened and case hardened notched machine components and high-pressure vessels are subjected to the stress fields induced by the external load and the residual stress ...

Abstract: This paper discusses the design and calibration of an ultrasonic transducer for continuously monitoring the subcritical growth of internal, part-through thickness defects in steel piping operating ...

Abstract: A fracture mechanics analysis has been made of brittle fractures encountered during a program of fatigue tests of welded plate T-joints. Fracture toughnesses are in reasonable agreement with ...

Abstract: This paper describes a computationally efficient weight function technique which can be used to estimate the opening-mode stress intensity factor around the perimeter of planar surface or embedded ...
