Available in PDF, EPUB and Kindle. Book excerpt: Dynamic ductile fracture of two phase material have been investigated in two stages. The first stage is a model study where an idealized two phase material, single crystal Cu SiO2 was used to study the initiation and growth of voids, the dislocation morphology and the other microscopic behavior that took place in the as-impacted speciment. Important findings are voids were nucleated from only a fraction of secondary particles SiO2, the larger strain has induced the higher void density, and the dislocation cell structures were formed with the average cell size being constant for the range of strain rates investigated. Analytical models were constructed with the aim of simulating the void growth in a two phase material subjected to high strain rate deformation, static void growth model and dynamic void growth model. A comparison of the void density indicated the static void growth model can predict the experimental results reasonably well for the smaller strain, but it fails to predict for the larger strain, while the dynamic void growth model can simulate the void growth well for the entire range of strain and strain rates. The second stage conducts a series of experiments on more realistic two phase materials, Al Si alloy and SiC(w) or SiC(p)/Al composite. The mode of the initiation and growth of voids was observed in the specimens that were impacted by Split Hopkinson bar test. The void density was also measured along the specimen axis and its values were compared with the analytical results by the static void growth model, resulting in a reasonably good agreement.

Book Synopsis Dynamic Fracture by : K. Ravi-Chandar
Download or read book Dynamic Fracture written by K. Ravi-Chandar and published by Elsevier. This book was released on 2004-10-16 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic fracture in solids has attracted much attention for over a century from engineers as well as physicists due both to its technological interest and to inherent scientific curiosity. Rapidly applied loads are encountered in a number of technical applications. In some cases such loads might be applied deliberately, as for example in problems of blasting, mining, and comminution or fragmentation; in other cases, such dynamic loads might arise from accidental conditions. Regardless of the origin of the rapid loading, it is necessary to understand the mechanisms and mechanics of fracture under dynamic loading conditions in order to design suitable procedures for assessing the susceptibility to fracture. Quite apart from its repercussions in the area of structural integrity, fundamental scientific curiosity has continued to play a large role in engendering interest in dynamic fracture problems In-depth coverage of the mechanics, experimental methods, practical applications Summary of material response of different materials Discussion of unresolved issues in dynamic fracture

Available in PDF, EPUB and Kindle. Book excerpt: Mechanisms of Deformation and Fracture contains the proceedings of the Interdisciplinary Conference on the Mechanisms of Deformation and Fracture held at the University of Luleå in Sweden on September 20-22, 1978. The papers explore the mechanisms underlying deformation and fracture of materials such as pearlite, metals, quartz, soils, and rocks. Results of theoretical and experimental studies on topics ranging from electromagnetic detection of low-cycle fatigue to stress and strain distribution in two-phase systems are presented. This book is comprised of 37 chapters and begins with a discussion on the interrelationships among solid mechanics, earth sciences, and material sciences. Subsequent chapters focus on the low-cycle behavior of case hardened steel; deformation and shear of normally consolidated flocculated kaolin; analytical modeling in inelasticity; creep mechanisms in clay; and initiation of crack growth at full plasticity. Plastic flow mechanisms and the rheological properties of the Earth's mantle are also examined, along with the fracture of glassy thermoplastics. The final chapter presents a thermodynamic model of consolidation in cohesive soils. This monograph will be a valuable resource for students and practitioners of mechanical engineering, metallurgy, materials science, and earth sciences.
Book Synopsis High-Pressure Shock Compression of Solids II by : Lee Davison
Download or read book High-Pressure Shock Compression of Solids II written by Lee Davison and published by Springer. This book was released on 1996 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume concerns the fracture and fragmentation of solid materials that occurs when they are subjected to extremes of stress applied at the highest possible rates. The plan for the volume is to address experimental, theoretical, and com putational aspects of high-rate dynamic fracture and fragmentation, with emphasis on recent work. We begin with several chapters in which the emphasis falls on experimental methods and observations. These chapters address both macroscopic responses and the microscopic cause of these re sponses. This is followed by several chapters emphasizing modeling-the physical explanation and mathematical representation of the observations. Some of the models are deterministic, while others focus on the stochastic aspects of the observations. Often, the ov\!rall objective of investigation of dynamic fracture and fragmentation phenomena is provision of a means for predicting the entire course of an event that begins with a stimulus such as an impact and proceeds through a complicated deformation and fracture pro cess that results in disintegration of the body and formation of a rapidly expanding cloud of debris fragments. Analysis of this event usually involves development of a continuum theory and computer code that captures the experimental observations by incorporating models of the important pheno mena into a comprehensive description of the deformation and fracture pro cess. It is to this task that the work of the last few chapters is devoted.

Book Synopsis Strain-hardening and Interaction Effects on the Growth of Voids in Ductile Fracture by : Dennis Michael Tracey
Download or read book Strain-hardening and Interaction Effects on the Growth of Voids in Ductile Fracture written by Dennis Michael Tracey and published by . This book was released on 1968 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth and coalescence of voids is a common mechanism of fracture in ductile materials. Analytical work on the problem to date has dealt mainly with isolated voids in perfectly plastic materials, so that strain hardening and interactions between neighboring voids have been neglected. These features of void growth are examined here, but only for a simple geometrical configuration. In particular, the growth of single infinitely long cylindrical voids in bodies of rigid-plastic, strain-hardening material is considered. Bodies with both finite and infinite dimensions normal to the void surface are included in the analysis. The exact relation among the pertinent variables: transverse stress, axial strain, hardening coefficient, void strain and void growth rate is presented. Solution via a bounding technique is given for two general cases. The first case is that of an imposed constant void growth rate and the second case is an imposed constant transverse stress. The results show a decelerating effect of hardening on void growth. Application to the ductile fracture problem of void growth in the neck of a tensile specimen demonstrates the accelerating effect of void growth due to interactions between voids. (Author).
