STUDY ON DYNAMIC J-INTEGRAL OF MECHANICAL HETEROGENEOUS WELDED JOINT D.Zhang1,X.Y.Li2,F.Q.Tian1,Y.W.Shi2,D.Y.He2 (1.Institute of Composite Materials, Shanghai Jiaotong University, Shanghai 200030, China;2.School of Materials Science and Engineering, Beijing Polytechnic University, Beijing 100022, China) Abstract:Welded joint is a mechanical heterogeneous body, and mechanical heterogeneity has......
with non-persistent joints are governed by cracking process of the rock bridges. The dependence of cracking process of jointed rock masses on the two important geometrical parameters, joint orientation and joint persistence, was studied systematically by carrying out a series of uniaxial compression tests on gypsum specimens with regularly arranged multiple parallel pre-existing joints. According......
Mineralization-related geochemical anomalies derived from stream sediment geochemical data using multifractal analysis in Pangxidong area of Qinzhou-Hangzhou tectonic joint belt, Guangdong Province.... A set of stream sediment geochemical data was obtained for 1 880 km2 of the Pangxidong area, which is in the southern part of the recently recognized Qinzhou-Hangzhou joint tectonic belt. This belt......
