From the Author's PrefaceThe objective of this book is to provide a thorough and systematic study of the problem of laminated composites containing stress concentrations. Stress concentrations are introduced in laminated plates in the forms of circular holes, elliptical openings and straight cracks. These forms of cutouts have many practical applications, and are familiar to most engineers. Stress concentrations exist in all known structural components. Stress concentrations have great practical importance because they are normally the cause of failure. In addition to stress analyses of laminated composites, we need more fundamental understanding of the failure mode, the failure criterion, the effects on global laminate response, and the design of composites in the presence of stress concentrations. In this book, all the subjects studied are closely related to the problem of stress concentrations in laminated composites . . . . All the models are verified with many experimental results. The underlying objective of this comprehensive study is to give the readers an in-depth and thorough understanding of the problem of stress concentrations in composites. This book is the first to address the problem of laminated composites containing stress concentrations in a systematic way.

Stress concentration factors are determined using a three-dimensional finite-element analysis for laminated composites pierced by circular, square and diamond-shaped holes. Both angel-ply and bidirectional laminates are investigated for hole size to width-of- strip ratios from 0.125 to 0.41. Normal stress concentrations are found to be the least for square holes and greatest for diamond-shaped holes. Interlaminar shear stress concentrations which cannot be determined by a two-dimensional analysis, are as large at the hole surface as those at the free edge when angle-ply laminates are utilized and the holes are large. For small circular holes, angle-ply (+ or -45) LAMINATES ARE RECOMMENDED. When large holes are present, bidirectional (90/0) laminates are shown to be more efficient. (Author-PL).
