Available in PDF, EPUB and Kindle. Book excerpt: The deformation and fracture of boron-reinforced 6061 aluminum and Ti-6A1-4V were examined using X-radiography. Both monofilament and multifilament containing specimens were tested to determine operative fracture mechanisms. It was shown that three distinctly different types of composite behavior could each provide substantial notch insensitivity.

Available in PDF, EPUB and Kindle. Book excerpt: It is reasonably well accepted that the standard procedures developed for isotropic homogeneous metals using linear elastic fracture mechanics models are not appropriate for either continuously or discontinuously reinforced metal matrix composites. For example, the ASTM plane strain fracture toughness test methods typically give widely different values of fracture toughness depending on the particular test specimen geometry as well as the fiber orientation. For unidirectional boron/aluminum composites one finds approximately a factor of two difference between the measured values of fracture toughness obtained from a center-notched test coupon and that given by a compact tension specimen. In particular for unidirectional composites, and to a slightly lesser degree for angle ply laminates, the dominant controlling mechanism for this behavior is matrix plasticity. A secondary toughening mechanism, resulting from the matrix plasticity, is stable transverse fiber failure. The present paper will focus on both the influence of the large plastic zone at the end of the notch and on the constraint that the fibers impose on the shape of this zone, as well as the transverse crack growth. First, a review of some particular experimental studies and methods of analysis for predicting crack growth and fracture of notched unidirectional metal matrix composites is given. Next, two mechanistic models for unidirectional composites with damage are presented. The first is an improved shear lag model that accounts for both of the above damage modes, and the second describes a recent extension of the shear lag concept in an attempt to include transverse stresses. A related finite width laminate model is then discussed, and it is indicated that an isotropic finite width correction factor is reasonably accurate for most center-notched test coupons.

This book was released on 1982 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This progress report describes the results of research work on the characterization of fracture behavior in boron/aluminum (B/Al) composites. Emphasis has been placed on the correlation between the observed failure modes and the deformation characteristics of center-notched B/Al composties, where particular attention has been given to the proper test procedure and analytical appraoch employed. The purpose of this work is not merely to generate and furnish quantitative data but also to discuss the appropriate methodology to be employed in characterizing a new composite material system. The investigation focused on the deformation characteristics, crack tip damage growth, fracture strength, notch sensitivity, and the associated characterization methods. Extensive acoustic emission information is reported and an attempt is made to distinguish among major failure mechanisms, and to monitor fatigue damage progression. Considerable care must be taken to distinguish between emission due to new damage growth and emission due to friction.

Book excerpt: Metal Matrix Composites: Thermomechanical Behavior discusses metal matrix composites, elaborating on that consists of two phases—fiber as reinforcement and metal as matrix. This book focuses on polymer matrix composites, including topics in metal matrix composites ranging from processing to fracture mechanics. The three basic types of composite materials—dispersion-strengthened, particle-reinforced, and fiber (whisker)-reinforced, are also described in detail. Dispersion-strengthened is characterized by a microstructure consisting of an elemental matrix within which fine particles are uniformly dispersed, while particle-reinforced is indicated by dispersed particles of greater than 1.0 μm diameter with a volume fraction of 5 to 40%. Fiber (whisker)-reinforced provides a distinguishing microstructural feature of fiber-reinforced materials, such as that the reinforcing fiber has one long dimension, while the reinforcing particles of the other two types do not. This publication serves as a reference data book to students and researchers aiming to acquire knowledge of the thermomechanical behavior of metal matrix composites.

Available in PDF, EPUB and Kindle. Book excerpt: The work of Dvorak et al. and Bahei-El-Din et al. on fracture of unidirectionally reinforced boron/aluminum specimens with a center notch is extended here for specimens with other types of discontinuities. The experimental results indicate that long, discrete plastic shear zones similar to those found at the notch tip are present in all specimens. The plastic zones grow from the discontinuity in the fiber direction. The measured fracture strength was not affected by geometry of the notch, it is only a function of the notch width/specimen width ratio. Finite element analysis of the specimens with center square hole provided the plastic zone length and the local stresses. The results verified that the criterion controlling fracture in center-notched specimens is applicable to other notch geometries. Namely, failure is controlled by a critical ratio of the largest principal stress to off-axis unnotched strength in the principal direction, in a small representative volume in the vicinity of the notch.

This book was released on 1976 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to improve the impact resistance of B/Al are reviewed and analyzed. Nonstandard thin-sheet Charpy and Izod impact tests and standard full-size Charpy impact tests were conducted on composites containing unidirectional 0.10-,0.14-, and 0.20-mm-(4-, 5.6-, and 8-mil- ) diameter boron fibers in 1100, 2024, 5052, and 6061 Al matrices. Impact failure modes of B/Al are proposed in an attempt to describe the mechanisms involved and to provide insight for maximizing impact resistance. The impact strength of B/Al was significantly increased by proper selection of materials and processing. The use of a ductile matrix (1100 Al) and large-diameter (8-mil) boron fibers gave the highest impact strengths. This combination resulted in improved energy absorption through matrix shear deformation and multiple fiber breakage.
