（Wright，Welch和JoUay）描述了多种多相材料。第四节（失效分析）包括的论文集中在预测复合材料的强度，断裂和/或失效的标准。具体而言，强度标准研究（Annin和Baev），弯曲条件下薄壁结构的失效（Nemirovsky），优化设计和强度（Obraztsov和Vasil'ev），断裂模型（Rikards，Teters和Upitis），失效特性对强度的影响（Perov、Skudra、Mashinskaja和Bulavs），自由边缘引起的失效分析（Crossman）、骨折（Knets）和疲劳寿命预测（Parfeyev、Oldirev、Tamuzs）。第五部分（实验方法）包含了关于复合材料实验行为的论文以及观察和测试它们的各种技术。包括损伤的无损研究（Roshenko，Matiss）、试验方法开发（Chamis）、裂纹扩展的性质（Bunsell）、光学方法（Rowlands和Stone）、高模量纤维的影响（Kalnin）、有趣的力学行为（Chiao）、断裂特性（Lachman）和断裂起始预测（Mast等人）。上述研究既包括单向增强层压板，也包括交叉层压板，既包括普通层压板（玻璃-环氧树脂），也包括高级层压板（石墨-铝等）。材料以及一些更奇特的（石棉水泥，骨组织）的多相材料。总的来说，这卷提出了一个总结，目前的方法和发展中涉及的断裂预测和相当广泛的多相材料的相关机制的考虑。的理论的局限性和限制进行了讨论和实验方法，并用于获得与分析预测比较的结果。该卷应提供一个窗口，以查看贡献者集体看到的复合断裂（一个正在发展但不完整的学科）的“最新技术水平”。因此，复合材料和断裂力学的工作者都应该对它感兴趣。
(Wright, Welch, and JoUay), were described for a variety of polyphase materials. Section IV (Failure Analysis) includes papers which focus upon criteria for predicting strength, fracture and/or failure of composite materials. Specifically, studies on strength criteria (Annin and Baev), failure of thin-walled structures under flexure (Nemirovsky), optimum design and strength (Obraztsov and Vasil'ev), fracture models (Rikards, Teters, and Upitis), influence of failure peculariities on strength (Perov, Skudra, Mashinskaja, and Bulavs), free edge induced failure analysis (Crossman), bone fracture (Knets), and fatigue life prediction (Parfeyev, Oldirev, Tamuzs) are presented. Section V (Experimental Methods) contains papers on the experimentally behaviors in composite materials and various techniques for observing and testing them. Included are nondestructive study of damage (Latishenko, Matiss), test method development (Chamis), the nature of crack growth (Bunsell), optical methods (Rowlands and Stone), effect of high modulus fibers (Kalnin), interesting mechanical behaviors (Chiao), fracture characteristics (Lachman), and fracture initiation prediction (Mast, et al.). The foregoing studies include both unidirectionally reinforced and crossply laminates and covered both common (glass-epoxy) and advanced (graphite-aluminum, etc.) materials as well as some more exotic (asbestos cement, bone tissue) of the polyphase materials. Taken collectively, this volume presents a summary of current approaches and considerations involved in developing predictions of the failure by fracture and its associated mechanisms of a fairly wide variety of polyphase materials. Limitations and restrictions of the theories are noted and experimental methods are discussed and used to obtain results for comparison with analytical predictions. The volume should provide a window for viewing a "state of the art" in composite fracture (a developing but incomplete discipline) as seen collectively by the contributors. As such, it should be found of interest to workers in both composite materials and fracture mechanics.
