This report investigates two of the most common modes of localized failures, namely, periodic fiber-bridged matrix cracks and transverse matrix cracks. A modification of Daniels' bundle theory is combined with Weibull's weakest link theory to model the statistical distribution of the periodic matrix cracking strength for an individual layer. Results of the model predictions are compared with experimental data from the open literature. Extensions to the model are made to account for possible imperfections within the layer (i.e., nonuniform fiber lengths, irregular crack spacing, and degraded in-situ fiber properties), and the results of these studies are presented. A generalized shear-lag analysis is derived which is capable of modeling the development of transverse matrix cracks in material systems having a general multilayer configuration and under states of full in-plane load. A method for computing the effective elastic properties for the damaged layer at the global level is detailed based upon the solution for the effects of the damage at the local level. This methodology is general in nature and is therefore also applicable to (0(sub m)/90(sub n))(sub s) systems. The characteristic stress-strain response for more general cases is shown to be qualitatively correct (experimental data is not available for a quantitative evaluation), and the damage evolution is recorded in terms of the matrix crack density as a function of the applied strain. Probabilistic effects are introduced to account for the statistical nature of the material strengths, thus allowing cumulative distribution curves for the probability of failure to be generated for each of the example laminates. Additionally, Oh and Finney's classic work on fracture location in brittle materials is extended and combined with the shear-lag analysis. The result is an analytical form for predicting the probability density function for the location of the next transverse crack occurrence within a crack bounded reg...

This book focuses on the matrix cracking behavior in ceramic–matrix composites (CMCs), including first matrix cracking behavior, matrix cracking evolution behavior, matrix crack opening and closure behavior considering temperature and oxidation. The micro-damage mechanisms are analyzed, and the micromechanical damage models are developed to characterize the cracking behavior. Experimental matrix cracking behavior of different CMCs at room and elevated temperatures is predicted. The book can help the material scientists and engineering designers to better understand the cracking behavior in CMCs.

This book provides readers with essential insights into composite materials, encompassing methods for fabricating composite parts (PMCs, MMCs, CMCs), determining their mechanical properties via coupon testing and rule of mixtures, and exploring their industrial applications. Additionally, the book covers topics of interest for engineers, including damage tolerance analysis, nondestructive inspections, repairing damaged composite and metallic parts, and fabricating composite parts using additive manufacturing processes. Drawing on his years of experience in the aerospace industry, the author believes the topics presented will be valuable to readers and that engineers in industries, students in academia, and university instructors will find this book beneficial. Introduces progressive failure analysis, fatigue, and fracture of composite, molecular dynamics, virtual testing, with several practical example problems Explores additive manufacturing methods and their application in fabricating PMCs and assessing mechanical properties Introduces nanocomposites and their fabrication methods, detailing advantages and disadvantages of the parts produced
