During the last ten years, our understanding of the perfect plasticity and the associated flow rule assumption on which limit analysis is based has increased considerably. Many extensions and advances have been made in applications of limit analysis to the area of soil dynamics, in particular, to earthquake-induced slope failure and landslide problems and to earthquake-induced lateral earth pressures on rigid retaining structures. The purpose of the book therefore is in part to discuss the validity of the upper bound work (or energy) method of limit analysis in a form that can be appreciated by a practicing soil engineer, and in part to provide a compact and up-to-date summary of recent advances in the applications of limit analysis to earthquake-induced stability problems in soil mechanics.
Developments in Geotechnical Engineering, Volume 7: Limit Analysis and Soil Plasticity covers the theory and applications of limit analysis as applied to soil mechanics. Organized into 12 chapters, the book presents an introduction to the modern development of theory of soil plasticity and includes rock-like material. The first four chapters of the book describe the technique of limit analysis, beginning with the historical review of the subject and the assumptions on which it is based, and then covering various aspects of available techniques of limit analysis. The subsequent chapters deal with the applications of limit analysis to what may be termed "classical soil mechanics problems that include bearing capacity of footings, lateral earth pressure problems, and stability of slopes. In many cases, comparisons of limit analysis solution and conventional limit equilibrium and slip-like solutions are also presented. Other chapters deal with the advances in bearing-capacity problem of concrete blocks or rock and present theoretical and experimental results of various concrete bearing problems. The concluding chapter examines elastic-plastic soil and elastic-plastic-fracture models for concrete materials. This book is an ideal resource text to geotechnical engineers and soil mechanics researchers.
This book establishes the equations of limit analysis and provides a complete theoretical basis for foundation capacity, slope stability, and earth pressure. It is divided into three parts, the first of which discusses the failure mode and fundamental equation of soil mass. The second part addresses the solution methods for limit analysis, including the characteristic line method, stress field method, limit equilibrium method, virtual work equation-based generalized limit equilibrium method and generalized limit equilibrium method for the surface failure mode. Lastly, the third part examines the application of the limit analysis theory to soil mass.
This book is a personal anthology of the author's utmost academic works and accomplishments with his former students and colleagues intended as an enduring record for the engineering community for many years to come.The author's forty-year professional career and academic life journey is first briefly sketched in Chapter 1 and more details are elaborated in three chapters that follow: Chapter 2: The first ten years at Lehigh — beginning to show; Chapter 3: Twenty=three years at Purdue — the highly productive years; and Chapter 4: seven years at UH — the pursuit of excellence. The author's specific academic contributions are documented in the following three chapters: Chapter 5: 23 academic bulletins are selected to highlight his 10 major research areas; Chapter 6: 23 Academic masterpiece books are listed along with their respective peer review comments; and Chapter 7: academic publications include journal articles, conference proceedings and symposiums, and lectures and keynotes. The book ends with the listing of all the author's 55 doctoral students' dissertation titles in Chapter 8.In 1975 at Lehigh, the author published a milestone treatise on Limit Analysis and Soil Plasticity. In 1982 at Purdue, he published another pioneering work on Plasticity in Reinforced Concrete.In September 1999, the author was recruited by UH to take the Deanship of the College of Engineering to accomplish the noble mission: to build the College to become one of the top 50 engineering schools by strengthening the faculty, improving the facilities, and increasing the enrollment. Over his seven years at UH, a lot of progress was made in all these three areas — the research program expanded, facilities improved, and enrollment increased.
