Book excerpt: Small cracks developing from rivet holes in lap joints of fuselage structure have been an issue of concern over the past decade. Stress-intensity factor solutions required to assess the structural integrity of such configurations are lacking. To address this need, the domain integral method was used in this research to obtain the mode I, normalized stress-intensity factor distributions for cracks emanating from a centrally located countersunk rivet hole in a square plate subjected to remote tension. Particular attention was focused on short cracks with an elliptical shape that have not propagated through the thickness. For these short cracks, the normalized stress-intensity factor distribution depended on the shape and size of the crack. Analysis was also conducted on long through the thickness cracks with a straight front for which the normalized stress-intensity factors were uniform.

Book excerpt: To predict crack growth and residual strengths of riveted joints subjected to widespread fatigue damage (WFD), accurate stress and fracture analyses of corner and surface cracks at a rivet hole are needed. The results presented in this report focus on the calculation of stress-intensity factor (SIF) solutions for cracks at countersunk rivet holes for tension, bending, and wedge load conditions. A wide range of configuration parameters were varied including the crack size, crack shape, and crack location as well as the length of the straight-shank hole. A finite element based global-intermediate-local (GIL) hierarchical approach was used in this study. The results are expressed as boundary correction factors (BCF), which is a nondimensional representation of the SIF. The boundary correction factors were determined along the crack front in terms of the physical angle, which was measured from the inner surface of the plate to a point on the hole boundary or the outer surface of the plate. In general, the values of boundary correction factors increased as one move along the crack front from the inner surface of the plate towards the hole boundary or the outer surface. The values of the boundary correction factor were highest for the crack fronts closest to the hole boundary. The trends in the solutions were the same for the three loading conditions.

Book excerpt: The second edition of this textbook includes a refined presentation of concepts in each chapter, additional examples; new problems and sections, such as conformal mapping and mechanical behavior of wood; while retaining all the features of the original book. The material included in this book is based upon the development of analytical and numerical procedures pertinent to particular fields of linear elastic fracture mechanics (LEFM) and plastic fracture mechanics (PFM), including mixed-mode-loading interaction. The mathematical approach undertaken herein is coupled with a brief review of several fracture theories available in cited references, along with many color images and figures. Dynamic fracture mechanics is included through the field of fatigue and Charpy impact testing.
