Book Description
This first of a kind reference/handbook deals with nonlinear models and properties of material. In the study the behavior of materials' phenomena no unique laws exist. Therefore, researchers often turn to models to determine the properties of materials. This will be the first book to bring together such a comprehensive collection of these models. The Handbook deals with all solid materials, and is organized first by phenomena. Most of the materials models presented in an applications-oriented fashion, less descriptive and more practitioner-geared, making it useful in the daily working activities of professionals. The Handbook is divided into three volumes. Volume I, Deformation of Materials, introduces general methodologies in the art of modeling, in choosing materials, and in the "so-called" size effect. Chapters 2-5 deal respectively with elasticity and viscoelasticity, yield limit, plasticity, and visco-plasticity. Volume II, Failures in Materials, provides models on such concerns as continuous damage, cracking and fracture, and friction wear. Volume III, Multiphysics Behavior, deals with multiphysics coupled behaviors. Chapter's 10 and 11 are devoted to special classes of materials (composites, biomaterials, and geomaterials). The different sections within each chapter describe one model each with its domain of validity, its background, its formulation, the identification of material parameters for as many materials as possible, and advice on how to implement or use the model. The study of the behavior of materials, especially solids, is related to hundreds of areas in engineering design and control. Predicting how a material will perform under various conditions is essential to determining the optimal performance of machines and vehicles and the structural integrity of buildings, as well as safety issues. Such practical examples would be how various new materials, such as those used in new airplane hulls, react to heat or cold or sudden temperature changes, or how new building materials hold up under extreme earthquake conditions. The Handbook of Materials Behavior Models: Gathers together 117 models of behavior of materials written by the most eminent specialists in their field Presents each model's domain of validity, a short background, its formulation, a methodology to identify the materials parameters, advise on how to use it in practical applications as well as extensive references Covers all solid materials: metals, alloys, ceramics, polymers, composites, concrete, wood, rubber, geomaterials such as rocks, soils, sand, clay, biomaterials, etc Concerns all engineering phenomena: elasticity, viscoelasticity, yield limit, plasticity, viscoplasticity, damage, fracture, friction, and wear

Book Description
The mechanical properties of materials are known to be rate- and temperature-dependent. Owing to this, investigations aimed towards the exploration of material behavior (i.e. plasticity, strength, and failure) under thermomechanical extremes has been a subject of sustained interest. The extreme temporal and precise nature of these studies produces special experimental challenges, and as a consequence, knowledge regarding the dynamic response of materials, especially in thermomechanical extremes, is still limited by the deficiency of experimental data. The main objectives of the current study are to 1) develop a reliable experimental scheme for investigating the dynamic inelasticity of metals under thermomechanical extremes. In particular, the focus is on elevated temperature dynamic compressive and shearing resistance of metals at plastic strain rates in excess of one-million/sec and sample temperatures approaching melt. And, 2) to address the need for experimental data on the dynamic response of FCC metals in previously unexplored but important thermomechanical regimes, such as elevated temperatures and plastic strain-rates on the order of 10^5 – 10^9 /s. In order to conduct this research, the single-stage gas-gun facility at CWRU was modified to include a breech-end sabot heater system and a novel fully fiber-optics based normal and transverse motion diagnostics system, which enabled reverse geometry normal and pressure-shear plate impact experiments to be conducted on pure aluminum at elevated temperatures. Additionally, a full characterization of the WC anvil plates was performed. Using these capabilities, elevated temperature normal and combined pressure-shear plate impact experiments were carried out to better understand the high temperature dynamic compressive and shearing resistance of aluminum. These experiments were used to shed light on the temperature-dependence of the shock impedance of aluminum at pressures of around 1.0 – 1.6 GPa, and the temperature-dependence of shear flow stress at levels of strain approaching 50% and strain-rates in the order of 4 – 8 x 10^5 /s. The results showed an overall decrease in the shear flow stress with temperatures in the range of 23 – 593 ̊C, showing that temperature facilitates plastic flow of aluminum when deforming at strain-rates approaching 10^6 /s. Additionally, in an effort to better understand the relaxation behavior of this material at incipient plasticity at ultra-high strain-rates, a series of laser-driven shock compression experiments are carried out on pure aluminum films at temperatures ranging from 23 – 400 ̊C. The results are used to correlate the temperature-dependence of the rate-sensitivity of the Hugoniot elastic limit (HEL) of pure aluminum at strain-rates up to 10^9 /s. In contrast to the previous case (i.e. large plastic strains, and lower strain-rates), the results reveal a monotonic increase in the HEL with temperature for strain-rates in the range of 10^4 – 10^9 /s. This effect is shown to decrease with increasing strain-rate.
