Crack branching mechanism of rock-like quasi-brittle materials under dynamic stressTANG Chun-an(唐春安), YANG Yue-feng(杨岳峰)(Center for Rock Instability and Seismicity Research, Dalian University of Technology, Dalian 116024, China)Abstract:The cracking patterns of a thin sheet with a pre-existing crack subjected to dynamic loading are numerically simulated to investigate the mechanism of crack......
thickness under spherical indentation are investigated within the framework of linear fracture mechanics. The J-integral associated to such cracks was computed. The evolution of J-integral vs the crack length... can improve the fracture resistance of the coating systems under the same indentation conditions through reducing the J-integral.关键词:......

Article ID: 1003-6326(2005)02-0473-05 Higher order asymptotic fields for mode Ⅰ crack in functionally gradient material DAI Yao(戴 耀)1, YAN Xiu-fa(燕秀发)1 (Department of Engineering Mechanics, Academy of Armored Force Engineering, Beijing 100072, China) Abstract: Higher order stress fields for a mode Ⅰ crack perpendicular to the direction of property variation in a functionally gradient......
resistance of concrete. In this experiment, the numbers of blows to first visible crack (N1) as well as to final failure (N2) were recorded. Thereafter, both of them were used to evaluate the impact... identification of the first crack, which may occur in any direction [9]. 2) The impact resistance of concrete is based on a single point of impact, which might happen to be on a hard particle of coarse......
