As suggested by the title, this extensive book is concerned with crack and contact problems in linear elasticity. However, in general, it is intended for a wide audience ranging from engineers to mathematical physicists. Indeed, numerous problems of both academic and technological interest in electro-magnetics,  相似文献

The discussion concerns a recently proposed definition of average stress for granular materials, one which can manifest asymmetry in the absence of surface couples, body couples, and contact couples. The average stress was derived from a new postulate that employs virtual work terminology. The discussion shows that the postulate leads to a non-unique average stress and to a non-unique stress asymmetry.  相似文献

Fluidization is an important process technology and is ubiquitously present in the process industry. The phenomena of fluidization also represent one of the most fascinating fluid-particle interactive behaviors in nature that are manifested by complex, intertwining science and engineering principles. Even though it is a centuries old practice, pursuit of the fundamental understanding of fluidization has its origins in the 1940s. Since the 1960s, fluidization has been a vibrant field for fluid mechanics, particle mechanics, as well as modeling and computation. From the historical perspective, Professor Mooson Kwauk and Professor Richard Wilhelm's 1948 article "Fluidization of Solid Particles," is proved to be a pioneering work that sets a stage for subsequent fundamental studies in the characteristics of fluidization. As the field has evolved over the last six decades, Professor Kwauk has been a leader of fluidization research in China and the world,  相似文献

苏联科学院院士Л.Д. Ландау是当代著名的理论物理学家。他和合著了一套理论物理学教程,“流体力学”便是其中的一卷。在这套教程中,1944年初版时流体力学和弹性理论合为一卷,书名“速续介质力学”;1953年第二版时,内容较前更加丰富。根据第二版1954年版译出的中译本,内容则仅限于流体力学。以后作者又把流体力学部分单独安排为一卷,列为共九卷的理论物理学教程中的第六卷。英译本  相似文献
