Abstract: The equivalence of the final stretch and crack tip opening angle criteria, as applied to the Dugdale-Bilby-Cottrell-Swinden type model for Mode I plane strain crack growth, is demonstrated. This ...

Abstract: Zahoor and Kanninen have recently developed a simple procedure for estimating the magnitude of the J-integral for through-wall cracks in pipes subjected to bending loads. This paper gives ...

Abstract: This paper provides an appraisal of a recent analysis for estimating the plastic component of the deformation J integral for a stationary crack. Such an estimation is a prerequisite when ...

Abstract: The status of photovoltaic power technology is reviewed primarily from the viewpoint of current and future applications of the technology to the exploration and utilization of space. The ...

Abstract: Engineering managers do not receive management training as part of their education. Training in management, situational leadership, in this instance, will give them a model to follow as they interact with others in the ...

Abstract: For longitudinally uniform stretches of waterways there is a mixing center for the across-channel location of a steady point source in steady flow, such that complete mixing is achieved as soon as possible and there is no ...

Abstract: The nature and magnitude of climatic changes associated with anticipated global warming are considered in terms of their implications for the permafrost regions. Extensive areas where permafrost is presently within a degree ...
