Book excerpt: In this ground-breaking book, John Koza shows how this remarkable paradigm works and provides substantial empirical evidence that solutions to a great variety of problems from many different fields can be found by genetically breeding populations of computer programs. Genetic programming may be more powerful than neural networks and other machine learning techniques, able to solve problems in a wider range of disciplines. In this ground-breaking book, John Koza shows how this remarkable paradigm works and provides substantial empirical evidence that solutions to a great variety of problems from many different fields can be found by genetically breeding populations of computer programs. Genetic Programming contains a great many worked examples and includes a sample computer code that will allow readers to run their own programs.In getting computers to solve problems without being explicitly programmed, Koza stresses two points: that seemingly different problems from a variety of fields can be reformulated as problems of program induction, and that the recently developed genetic programming paradigm provides a way to search the space of possible computer programs for a highly fit individual computer program to solve the problems of program induction. Good programs are found by evolving them in a computer against a fitness measure instead of by sitting down and writing them.

This book was released on 2013-07-17 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The choice of a material for a certain application is made taking into account its properties. If, for example one would like to produce a table, a hard material is needed to guarantee the stability of the product, but the material should not be too hard so that manufacturing is still as easy as possible - in this simple example wood might be the material of choice. When coming to more advanced applications the required properties are becoming more complex and the manufacturer`s desire is to tailor the properties of the material to fit the needs. To let this dream come true, insights into the microstructure of materials is crucial to finally control the properties of the materials because the microstructure determines its properties. Written by leading scientists in the field of microstructural design of engineering materials, this book focuses on the evolution and behavior of granular microstructures of various advanced materials during plastic deformation and treatment at elevated temperatures. These topics provide essential background and practical information for materials scientists, metallurgists and solid state physicists.

Available in PDF, EPUB and Kindle. Book excerpt: Martensitic Transformation examines martensitic transformation based on the known crystallographical data. Topics covered range from the crystallography of martensite to the transformation temperature and rate of martensite formation. The conditions for martensite formation and stabilization of austenite are also discussed, along with the crystallographic theory of martensitic transformations. Comprised of six chapters, this book begins with an introduction to martensite and martensitic transformation, with emphasis on the basic properties of martensite in steels such as carbon steels. The next two chapters deal with the crystallography of martensite and discuss the martensitic transformation behavior of the second-order transition; lattice imperfections in martensite; and close-packed layer structures of martensites produced from ? phase in noble-metal-base alloys. Thermodynamical problems and kinetics are also analysed, together with conditions for the nucleation of martensite and problems concerning stabilization of austenite. The last chapter discusses the theory of the mechanism underlying martensitic transformation. This monograph will be of interest to metallurgists and materials scientists.

Available in PDF, EPUB and Kindle. Book excerpt: The present collection of articles focuses on the mechanical strength properties at micro- and nanoscale dimensions of body-centered cubic, face-centered cubic and hexagonal close-packed crystal structures. The advent of micro-pillar test specimens is shown to provide a new dimensional scale for the investigation of crystal deformation properties. The ultra-small dimensional scale at which these properties are measured is shown to approach the atomic-scale level at which model dislocation mechanics descriptions of crystal slip and deformation twinning behaviors are proposed to be operative, including the achievement of atomic force microscopic measurements of dislocation pile-up interactions with crystal grain boundaries or with hard surface coatings. A special advantage of engineering designs made at such small crystal and polycrystalline dimensions is the achievement of an approximate order-of-magnitude increase in mechanical strength levels. Reasonable extrapolation of macro-scale continuum mechanics descriptions of crystal strength properties at micro- to nano-indentation hardness measurements are demonstrated, in addition to reports on persistent slip band observations and fatigue cracking behaviors. High-entropy alloy, superalloy and energetic crystal properties are reported along with descriptions of deformation rate sensitivities, grain boundary structures, nano-cutting, void nucleation/growth micromechanics and micro-composite electrical properties.

Download or read book Micromechanical Modeling of Size-dependent Crystal Plasticity and Deformation Twinning written by Edgar Husser and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The computational modeling and simulation of the deformation behavior of crystalline materials at the micron scale is the objective of this thesis. Numerous experimental studies have proven that small-scaled metallic probes behave mechanically different from their bulk counterparts, in particular, the yield strength and work hardening behavior is affected in the way that smaller single crystals behave stronger. This characteristic behavior opens up new design possibilities for further improvement of mechanical properties of engineering material systems. In view of high expenses for advanced and complex experimental work along with the inherent testing limitations, numerical methods offer a great option to validate experimental findings, support the development of suitable theories, and extend scientific investigations on a computer-aided basis. A gradient crystal plasticity model is presented in this thesis and applied to selected scientific problems including the mechanical testing of single crystals via simulation of microcompression and microbending using a three-dimensional finite element framework. The model is implemented on an element basis and linked to the commercial finite element software Abaqus via the user subroutine UEL. Two major deformation mechanism are considered by the underlying model. Deformation via crystallographic slip is modeled in a non-local fashion allowing to account for gradient effects. Geometrically necessary dislocation (GND) densities associated with plastic slip gradients are introduced as additional nodal degrees of freedom while the actual plastic slip variables are handled as internal variables. Deformation twinning is accounted for in terms of a simple shear deformation associated with shear and shuffling of atoms. In addition, the twinning-induced reorientation of the crystal lattice is fully considered along with subsequent activation of slip modes within the twinned region. In accordance to the non-local crystal plasticity framework, the gradient of the twin volume fraction is introduced at the nodal level. The actual twin volume fraction is treated as an extended internal variable yielding a coupled system of highly non-linear equations at the local level. The competitive nature between slip deformation and deformation by twinning is addressed by physically motivated interaction relations. The characteristic features of the model are portrayed for a variety of micromechanical problems and in relation to experimental results.
