- Finally , an energy approach is combined with the fem in the simulation of the crack propagation along the fiber / matrix interface in a pull out process . the simulated results are in nice conformity with experimental results . the second part of the research deals with the characterization of the failure process in the fragmentation tests , which is one of the most frequently used test methods in studying thermal mechanical properties of fiber / matrix interfaces
在这一部分工作的最后,采用能量法与有限元法结合起来,模拟纤维抽拔试验中裂纹的扩展:针对以往研究工作中的不足之处,在模拟中使用能量释放率,在表征界面破坏时,所使用的应力强度因子考虑了纤维和基体两种材料的不同属性,并考虑裂纹尖端的单元奇异性,来研究裂纹长度和温度对裂纹扩展的影响。 - Currently , the main methods used to measure the fiber / matrix interface properties of composite were based on micro - mechanics , including single - fiber composites fragmentation test ( sfc ) , micro - debonding technique , single - fiber pull - out test , and single - fiber push - out test , in which sfc was most widely used
目前直接用来测定纤维增强复合材料界面力学性能的主要微观力学方法有单纤维复合材料断裂实验( sfc ) 、微脱粘方法、单纤维拔出法、单纤维顶出法,其中以单纤维复合材料断裂实验的应用最为广泛。 - These include the single fiber pull out tests , single fiber fragmentation tests , etc . however , experimental work is time consuming and its outcomes are not always repeatable , while analytical solutions are not usually available for solving such complex problems as the characterizations of the interfacial mechanical properties of fiber reinforced composites
目前在这一领域内常用的研究和分析方法有试验、解析法以及数值解法。但试验方法费时费力,结果的可重现性较差,而且对纤维增强复合材料的界面问题几乎无法得到解析解。 - Here , fem is applied in the analyses of i ) fiber axial stress and interphase shear stress in fragmentation tests during initially applied strain , ii ) influence of temperature on the stress transfer across the interface , iii ) modulus and thickness of the interphase and their influence on interfacial stress transfer , iv ) interfacial debonding process , and v ) fragment aspect ratio , contact friction along the interface and their influences to the interfacial stress transfer efficiency
在论文的这部分工作中,使用有限元法描述和分析了逐节断裂试验中初始应变下的纤维轴向应力和界面相剪切应力,温度对界面应力传递的影响,界面相模量和厚度、纤维节长宽比、界面脱粘过程、界面接触中的摩擦效应等因素对逐节断裂试验中应力传递的影响。 - Research work described in this dissertation consists of four parts : application of finite element methods ( fem ) in the study of pull out tests of single fiber reinforced composites ( sfrc ) , fem study of fragmentation tests for single fiber reinforced composites , monte carlo simulation of fragmentation tests for single fiber reinforced composites , and a simulation of impact failure behaviors of fiber composites with a mesh free method - the sph method
