STUDY ON THE TENSILE FATIGUE DAMAGE OF QUASI-ISOTROPIC COMPOSITE LAMINATES I.S.Kim1,I.G.Kim2,O.S.Kim3,Yaragarra K.D.V.Prasad4 (1.Department of Mechanical Engineering, Mokpo National University, 61... of the interlaminar stresses. It wasconfirmed by tensile fatigue tests that the [0/-60/60]s laminate does not show any vis-ible fatigue damage, but the [30/-30/90]s laminate develops edge-delamination......

Molecular Dynamics Simulation of Tensile Deformation and Fracture of γ-TiAl with and without Surface DefectsH.N.Wu,D.S.Xu,H.Wang,R.YangInstitute of Metal Research, Chinese Academy of Sciences摘 要... deformation and fracture of γ-TiAl single crystals.The results indicate that brittle fracture occurs in perfect bulk; surfaces and edges will be detrimental to the strength of materials and provide......
. The fracture of the inclusion particles is induced when the accumulation of cyclic loading reaches the ultimate tensile strength[12]. In Figs.3(c) and (d), thousands of inclusion particles are located near...

Tensile and Fracture Properties of 15 vol% SiC_p/2009Al Composites Fabricated by Hot Isostatic Pressing and Hot Extrusion ProcessesJunhui Nie,Jianzhong Fan,Shaoming Zhang,Shaohua Wei,Tao Zuo,Zili Ma...) composites were fabricated by hot isostatic pressing(HIP) and hot extrusion processes. The tensile and fracture properties of 15 vol% Si Cp/2009 Al were studied. The results showed that hot extrusion......
cracking due to severe oxidation of element V and the secondary tensile stresses. The critical fracture strain increases with increasing temperature and decreasing strain rate. From these observations...

, but they were focused mainly on the high temperature tensile, wear and tear properties[4]. There were little studies on the fracture toughness of ZL108 alloy. It is believed that the fracture toughness... Effect of titanium addition on fracture toughness behavior of ZL108 alloy WENG Yong-gang(翁永刚), LI Zi-jing(李姿景), LIU Zhi-yong(刘志勇), LIU Wen-cai(刘文才), WANG Ming-xing(王明星), SONG Tian-fu(宋天福) Key......
sensitive to tensile loading than compressive loading, since the tensile strength of rock is much lower than compressive strength. The fracture characteristics of rock in the tensile state are of great... initiation, propagation, and coalescence. Therefore, tensile crack behaviors will vary with the heterogeneity. In the framework of fracture mechanics, theoretical and experimental researches on cracking......
