Growth of Cracks By Intergranular Cavitation in Creep,calized in the symmetry plane ahead of a blunt notch. These results are in excellent agreement with the experimental observations of Ozmat, et al. on the directions of early crack growth from sharp cracks and blunt notches in Type 304 stainless steel.Ingest 发表于 2025-3-23 22:42:25
Void Growth in Plastic Solids,ditional considerations, including the effect of the constraint provided by contact between the growing void and the void-nucleating particle, cavitation, and the effect of non-uniform porosity distributions are briefly noted.赦免 发表于 2025-3-24 03:05:49
,Metal Fatigue — A New Perspective, to fatigue fracture e.g. the Basquin and Coffin-Manson type studies..By introducing micro-structural fracture mechanics and elastic-plastic fracture mechanics it is possible to link the deformation and the fracture approaches to metal fatigue investigations. This chapter considers these developments and their implications.伪善 发表于 2025-3-24 09:42:10
Reflections on Contributions to Deformation and Fracture,am also deeply indebted to the many colleagues in the field, whose findings have often been greater, and with whom discussion have been exciting and instructive. Finally, the essential support of this work by many agencies over the years is very much appreciated. The topics are in order of their first major publication.祝贺 发表于 2025-3-24 14:40:32

D. M. Parks a promising sustainable source of many bioactive substances and their potential applications in pharmaceuticals, cosmeceuticals, and nutraceuticals industries. They contain different specific habitats characterized by a wide range of temperatures, hydrostatic pressures, and salinity. To survive in付出 发表于 2025-3-25 01:26:43
J. W. Hancocks the end of the Pre-Cambrian. Marine cyanobacteria are not only an important source of atmospheric oxygen, but they are also prolific manufacturers of secondary metabolites, frequently in spite of having incredibly small genomes. These organisms create a wide variety of complex secondary metabolite
