Concrete Fracture Models and Applications【電子書籍】[ Shailendra Kumar ]

＜p＞Cementitious materials, rocks and fibre-reinforced composites commonly termed as ＜em＞quasibrittle＜/em＞, need a different fracture mechanics approach to model the crack propagation study because of the presence of significant size of fracture process zone ahead of the crack-tip. Recent studies show that concrete structures manifest three important stages in fracture process: crack initiation, stable crack propagation and unstable fracture or failure. Fracture Mechanics concept can better explain the above various stages including the concepts of ductility, size-effect, strain softening and post-cracking behavior of concrete and concrete structures.＜/p＞ ＜p＞The book presents a basic introduction on the various nonlinear concrete fracture models considering the respective fracture parameters. To this end, a thorough state-of-the-art review on various aspects of the material behavior and development of different concrete fracture models is presented. The development of cohesive crack mod．．．楽天市場のショップで商品詳細の続きを見る
