The influence of the porosity on tensile strength of the composites is discussed. Three models of the composites (fiber being parallel, perpendicular and at an angle of 45° to tensile axis) are analyzed using finite element, and the stress distribution in fiber, matrix and at interface are discussed in detail. dc.description.sponsorship 四川省应用基础研究重点项目 dc.language.iso zh_CN dc.subject 界面 dc.subject 孔隙率 dc.subject 强度 dc.subject 有限元 dc.subject 应力 dc.subject interface, porosity, tensile strength, finite element, stress dc.title Al_2O_3纤维增强Al合金复合材料界面孔隙率测定及复合材料应力分布有限元计算 dc.title.alternative Measurement of Interfacial Porosity and Finite Element Analysis of Stress Distribution in Al_2O_3-Fiber-Reinforced Aluminium Alloy Composites dc.type Article
