This book was released on 2018-10-26 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three-dimensional finite-element and finite-alternating methods were used to obtain the stress-intensity factors for small surface and corner cracked plates subjected to remote tension and bending loads. The crack-depth-to-crack-length ratios (a/c) ranged from 0.2 to 1 and the crack-depth-to-plate-thickness ratios (a/t) ranged from 0.05 to 0.2. The performance of the finite-element alternating method was studied on these crack configurations. A study of the computational effort involved in the finite-element alternating method showed that several crack configurations could be analyzed with a single rectangular mesh idealization, whereas the conventional finite-element method requires a different mesh for each configuration. The stress-intensity factors obtained with the finite-element-alternating method agreed well (within 5 percent) with those calculated from the finite-element method with singularity elements.

This book was released on 1970 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Irwin stress intensity factor for surface cracks with crack depths less than half the plate thickness is extended to cases of relatively deep cracks by including the effect of the free surface opposite the crack. The stress intensity magnification factor is given as a function of applied load, crack length, crack depth, sheet thickness, yield strength, and Poisson's ratio. The combinations of these variables for which the plastic zone extends completely through the thickness a r e also predicted. The range of applicability of the analysis to surface-crack specimen data was investigated in terms of crack-depth-to-specimen-thickness ratio and crack depth-to-length ratio.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to present, describe and demonstrate the use of numerical methods in solving crack problems in fracture mechanics. The text concentrates, to a large extent, on the application of the Boundary Element Method (BEM) to fracture mechanics, although an up-to-date account of recent advances in other numerical methods such as the Finite Element Method is also presented. The book is an integrated presentation of modem numerical fracture mechanics, it contains a compilation of the work of many researchers as well as accounting for some of authors' most recent work on the subject. It is hoped that this book will bridge the gap that exists between specialist books on theoretical fracture mechanics on one hand, and texts on numerical methods on the other. Although most of the methods presented are the latest developments in the field of numerical fracture mechanics, the authors have also included some simple techniques which are essential for understanding the physical principles that govern crack problems in general. Different numerical techniques are described in detail and where possible simple examples are included, as well as test results for more complicated problems. The book consists of six chapters. The first chapter initially describes the historical development of theoretical fracture mechanics, before proceeding to present the basic concepts such as energy balance, stress intensity factors, residual strength and fatigue crack growth as well as briefly describing the importance of stress intensity factors in corrosion and residual stress cracking.
