Book Description
In recent years, fibrous composite materials have been widely used in aerospace and automobile industries due to their high modulus and strength to weight ratio. Particulate composites, though not as effective as the continuous fibrous composites in improving modulus and strength of the matrix materials, are also widely used in construction and commodity industries for their improved performance over the matrix material in, for example, thermal and electrical conductivities, friction and wear resistance, machinability, surface hardness, and cost effective. However, much of the studies about the particle reinforced polymeric composites are on the derivation of the effective elastic properties and the development of the constitutive models of the materials. In recent years, a considerable amount of work has been done in studying the crack growth behavior in highly filled polymeric materials. These materials consist of hard particles contained in a soft elastomeric binder. Experimental results indicate that power law relationships exist between the crack growth rate and the Mode I stress intensity factor which are consistent with the theories developed by Knauss and Schapery in their study of crack growth in viscoelastic materials.

Book Description
In this study, the local damage mechanisms and strain fields near the crack tip as well as the crack growth behavior in an centrally-cracked sheet specimen was investigated. The specimen was made of a particulate composite material containing hard particles embedded in a rubbery matrix and it was subjected to a constant strain rate of 0.5/min at room temperature. The effects of the applied strain level on the local damage and fracture processes as well as the strain fields near the crack tip were investigated and the results are discussed.

Book Description
Contains 26 papers presented at the International Conference on [title], held to address the latest ideas concerning the mechanisms and mechanics of composite fractures. The main focus was on the "driving forces" behind the various damage events in the inorganic composites at both micro and macro levels. The papers are grouped in five sections: deformation and damage in particulate composites; crack initiation and propagation; micromechanical modeling; fracture and fatigue; and microstructural tailoring, impact, and creep.

Book Description
Understanding damage and failure of composite materials is critical for reliable and cost-effective engineering design. Bringing together materials mechanics and modeling, this book provides a complete guide to damage, fatigue and failure of composite materials. Early chapters focus on the underlying principles governing composite damage, reviewing basic equations and mechanics theory, before describing mechanisms of damage such as cracking, breakage and buckling. In subsequent chapters, the physical mechanisms underlying the formation and progression of damage under mechanical loads are described with ample experimental data, and micro- and macro-level damage models are combined. Finally, fatigue of composite materials is discussed using fatigue-life diagrams. While there is a special emphasis on polymer matrix composites, metal and ceramic matrix composites are also described. Outlining methods for more reliable design of composite structures, this is a valuable resource for engineers and materials scientists in industry and academia.

Book Description
This book provides an overview of the surface effects at the interface boundary of metal/sand moulds, and their influence on the surface quality, microstructure and mechanical and anticorrosive properties of high-quality cast iron. It explores utilitarian aspects of the production of high-quality cast iron castings, including thin-walled castings of high-quality cast iron alloys, and examines problems related to the determination of moulding sands and reclaim quality, and their influence on castings. Presenting new material, this book takes into account the influence of metal quality, pouring temperature, solidification time, the quality of moulding sand with the reclaim application, as well the binders of moulding sands, on the formation of the degenerated graphite near surface layers. It also employs the latest research methods, such as a wavelength-dispersive spectrometer (WDS) analysis and thermodynamic calculations, which were carried out on the reactions occurring in the study area. Providing a valuable resource to academics and researchers interested in materials science, metal casting and metallurgy, this book is also intended for metal industry professionals.
