The modern counterparts are fracture mechanics, as invented by Irwin, and dislocation mechanics, as initiated in pioneering work by Cottrell. No less important was the breakthrough development of optical characterization of sectioned polycrystalline metal microstructures started by Sorby in the late 19th century and leading eventually to modern optical, x-ray and electron microscopy methods for assessments of crystal fracture surfaces, via fractography, and particularly of x-ray and electron microscopy techniques applied to quantitative characterizations of internal dislocation behaviors. A major current effort is to match computational simulations of metal deformation/fracturing behaviors with experimental measurements made over extended ranges of microstructures and over varying external conditions of stress-state, temperature and loading rate. The relation of such simulations to the development of constitutive equations for a hoped-for predictive description of material deformation/fracturing behaviors is an active topic of research. The present collection of articles provides a broad sampling of research accomplishments on the two subjects.Research & information: generalbicsscdislocation mechanicsyield strengthgrain sizethermal activationstrain rateimpact testsbrittleness transitionfracturingcrack sizefracture mechanicsHall-Petch equationGriffith equationsize effectmechanical strengthpearlitic steelssuspension bridge cablesdislocation microstructurefractal analysisplasticityrepresentative volume elementdislocation structuredislocation correlationsdislocation avalanchesnanotwinnanograinAu–Cu alloymicro-compressionCu-ZrECAPdeformationquasi-stationarysubgrainsgrainscoarseningCu–Zrultrafine-grained materialdynamic recoverytransientload change testsCharpy impact testGMAWadditive manufacturingsecondary cracksanisotropylinear flow splittingcrystal plasticityDAMASKtextureEBSDcrack tip dislocationsTEMgrain rotationfatiguedislocation configurationsresidual stressindentationserrationtemperaturedislocationartificial agingsolid solutionloading curvaturealuminum alloyholistic approachdislocation group dynamicsdynamic factordislocation pile-upyield stressdislocation creepfatigue crack growth rateResearch & information: generalArmstrong Ronald Wedt1304460Armstrong Ronald WothBOOK9910557594903321Dislocation Mechanics of Metal Plasticity and Fracturing3027441UNINA
