The classical approaches to finite deformations of elastic materials describe a dozen or more measures of stress and strain. These classical approaches require an in-depth knowledge of tensor analysis and provide little instruction as to how to relate the derived equations to the materials to be described. This text, by contrast, introduces only one strain measure and one stress measure. No tensor analysis is required. The theory is applied by showing how to measure material properties and to perform computer simulations for both isotropic and anisotropic materials. The theory can be covered in one chapter for students familiar with Euler-Lagrange techniques, but is also introduced more slowly in several chapters for students not familiar with these techniques. The connection to linear elasticity is provided along with a comparison of this approach to classical elasticity. Explains ably simulation of materials undergoing large deformations Illustrates a simpler mathematical base to build thermodynamic and viscoelastic theories Describes how experimenters can make better numerical descriptions of deformable bodies.MaterialsFatigueMechanics, AppliedContinuum mechanicsPhysicsStaticsMaterialsMaterials FatigueEngineering MechanicsContinuum MechanicsClassical and Continuum PhysicsMechanical Statics and StructuresMaterials EngineeringMaterialsFatigue.Mechanics, Applied.Continuum mechanics.Physics.Statics.Materials.Materials Fatigue.Engineering Mechanics.Continuum Mechanics.Classical and Continuum Physics.Mechanical Statics and Structures.Materials Engineering.531.382620.11232Hardy Humphrey1265497MiAaPQMiAaPQMiAaPQ9910624302003321Engineering Elasticity2967871UNINA03837nam 2200697Ia 450 991097113870332120200520144314.09781523117154152311715X97815805368751580536875(CKB)1000000000239589(EBL)227675(OCoLC)123129434(SSID)ssj0000151622(PQKBManifestationID)11137138(PQKBTitleCode)TC0000151622(PQKBWorkID)10319484(PQKB)11433366(Au-PeEL)EBL227675(CaPaEBR)ebr10082047(OCoLC)56985803(CaBNVSL)mat09100226(IEEE)9100226(MiAaPQ)EBC227675(Perlego)4668266(EXLCZ)99100000000023958920040514d2004 uy 0engur|n|---|||||txtccrEW 102 a second course in electronic warfare /David L.

Without delving into complex mathematics, this book gives engineers, defense contractors, managers, and government procurers a basic working knowledge of the technologies deployed in today's electronic warfare (EW) systems. Organized into chapters with new introductory and supplementary material from the author, this unique book includes tutorials on radar characteristics, infrared and electro-optical systems, signal jamming, spectrum spreading, satellite communications, and emitter location systems. A thorough and challenging problem set for each class of EW technology covered in the book, complete with solutions, helps readers to evaluate EW systems and their applications.Artech House radar library.Electronic warfare 102Electronics in military engineeringInformation warfareElectronics in military engineering.Information warfare.623.043623.043Adamy David536436MiAaPQMiAaPQMiAaPQBOOK9910971138703321EW 1024358175UNINA
