Experimental evidence is presented to support the hypothesis that a Griffith-type theory (Phil. Trans. Roy. Soc. of London, 221:163, 1920) is not the critical condition for the initiation of brittle fracture in steel plates. The data indicate almost complete size independence for notched, compressively prestrained, Project E steel specimens of 6 2/3-, 10-, and 20-in. widths, which had geometrically similar dimensions in the plane of the plate but were of the same thickness.

Nearly 500 years ago, Leonardo da Vinci observed that long wires are weaker than short wires of the same diameter. The statistical theory of extreme values (weakest-link theory) plays a very important role in studies of the size effect; competing theories include the energy theory and the technological theory. Summaries are given of relevant publications identified in the course of a literature survey on the size effect. Since this survey was motivated by concern about the reliability of large composite aircraft structures, which are now coming into use, special attention is given to the size effect on composite materials and structures. An attempt is made to summarize the present state of knowledge and to identify unsolved problems requiring further research.

Brittle Fracture in Steel Structures emphasizes the prevention of brittle fracture in structures fabricated from mild and low alloy steel operating at normal ambient temperatures. This book is divided into seven chapters. Chapter 1 provides the historical background and summarizes numerous case histories of brittle fractures. The nature of the phenomenon and factors that influence brittle fracture, including various methods of testing to determine the notch ductilities of different steels are described in Chapters 2 to 4. The fifth chapter elaborates the design considerations affecting the choice of steel for structural applications. Chapter 6 reviews the main methods for assessing the degree of notch ductility needed for different applications, while Chapter 7 deliberates practical procedures, recommended by the Navy Department Advisory Committee on Structural Steels, for assessing the suitability of different steels for particular applications. This publication is beneficial to metallurgists and welders intending to acquire knowledge of mild steel structures fabricated by welding from rolled steel plates and sections.

Studies in Applied Mechanics, Volume 6: Mechanics of Material Behavior provides information pertinent to the fundamental aspects of the mechanics of material behavior. This book discusses the theory of plasticity and its application to the design of engineering components and structures. Organized into 24 chapters, this volume begins with an overview of the concept of material stability, which provided a unified approach for the derivation of stress–strain relations for the plastic behavior of metals. This text then examines the general equation for the plane-stress condition of orthotropic sheet material that is isotropic in its plane. Other chapters consider the developments in plasticity as applied to soil mechanics, with emphasis on applications to earthquake-induced landslide problems. This book discusses as well the restrictions on a hypothesized quasi-statically propagating planar surface. The final chapter deals with the effects of fiber orientation, delamination length, and ply thickness on the interlaminar fracture. This book is a valuable resource for engineers.
