This book was released on 1994 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crack-tip opening displacement (CTOD) tests and large deformation finite element analyses have been carried out for double-edge notched tension [DE(T)] specimens with a/W = 0.9 [DE(T)9] and 0.5 [DE(T)5], single-edge notched tension [SE(T)] specimens with a/W = 0.5 [SE(T)5], three-point bend [SE(B)] specimens with a/W = 0.5 [SE(B)5] and 0.1 [SE(B)1], and center-cracked tension [M(T)] specimens with a/W = 0.5 [M(T)5]. The results of the CTOD tests show that the fracture toughness of the material decreases, and a ductile-brittle fracture transition takes place as the in-plane plastic constraint of the specimens increases. In M(T)5 and SE(B)1 specimens with low constraints, fracture is ductile and no transition occurs. In DE(T)5, SE(T)5, and SE(B)5 with higher constraints, fracture initiates by ductile tearing and then changes to cleavage. In the DE(T)9 specimens with the highest constraint, fracture initiates by brittle cleavage. The results of the finite element analyses show that the maximum achievable tensile stress outside the finite strain zone ahead of the crack tip increases with increasing plastic constraint in the order of M(T)5, SE(B)1, DE(T)5, SE(T)5, SE(B)5, and DE(T)9. The ductile-brittle transition is due to the maximum tensile stress ahead of the crack tip reaching the critical stress for cleavage fracture as the plastic constraint increases.

Available in PDF, EPUB and Kindle. Book excerpt: Classical plasticity is a well established domain of mechanics and engineering, providing the basis for many engineering structural design, manufacturing processes and natural phenomena. New important characteristics are emerging in the interdisciplinary approach of micro-, meso- and macro-mechanics, and through analysis, experiments and computation.The interaction of mechanics and materials scientists is introducing tremendous changes in the two disciplines, so that the possibility of materials being processed on the microscale to achieve the desired macroscopic properties is rapidly approaching.A comprehensive overview on the latest developments in both macroplasticity and microplasticity theories, their interactions and applications in various engineering disciplines such as solid mechanics, structural analysis and geo-mechanics, materials science and technology, and metal forming and machining, is given in this volume. Case studies written by international experts focus on aspects such as the applications of plasticity in interdisciplinary and non-conventional areas. The 150 papers provide a current and useful reference source on the latest advances for both research workers and engineers in the various fields of plasticity.

This book was released on 1997 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This symposium, held during Materials Week '97 in Indianapolis, Indiana, September 14-18, 1997, was dedicated to Dr. George R. Erwin, Professor Emeritus of the University of Maryland. The symposium proceedings is a collection of 29 papers and 10 abstracts on the subjects of fracture mechanics; dislocation theory of fracture; atomistic fracture; micromechanical and microstructural modeling of cleavage; cleavage mechanisms, fractographic characterization; experimental techniques; and cleavage studies in metals, welds, intermetallics, ceramics, and minerals. The diverse topics reflect the wide range of disciplines that Professor Irwin has impacted through his pioneering work on fracture mechanics.

This book was released on 1984 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of geometry on fracture toughness of steel in the ductile-to-brittle transition region has been studied. The critical crack-tip opening displacement (CTOD) and the critical J-integral have been measured as a function of temperature for ten fracture specimen configurations of ABS grade EH36 steel. A technique was developed to experimentally measure crack-tip constraint. Constraint decreased with crack blunting. This relaxation in constraint was modeled by a simple spring analog. The model was used to predict ductile-to-brittle transition curves for hypothetical structures. Some of the applications and limitations of the model are discussed.
