This monograph by L. B. Freund covers fundamental aspects of dynamic fracture mechanics, a topic that has not been previously compiled into a book. The author, a leading contributor to the field, presents the basic mathematical developments over the past 20 years, providing a solid foundation for further research. The book addresses the challenges of dynamic fracture, such as the lack of closed-form solutions for problems involving dynamically running cracks, and discusses recent advancements in the interpretation of experiments and fracture criteria. Key topics include continuum mechanics, experimental data on stationary cracks, asymptotic behavior of stress and strain-rate fields, energy concepts, and the dynamics of running cracks in elastic and elastic-plastic materials. The book is suitable for researchers and graduate students in fracture mechanics and elasticity, serving as both a textbook and a reference. This book by J. Lubliner serves as a comprehensive resource for advanced undergraduate and graduate students, as well as researchers in solid and applied mechanics. It covers modern developments in plasticity theory, including constitutive theories, continuum thermodynamics, large deformations, and numerical methods. The book includes traditional topics such as elastic-plastic boundary value problems, slip line theory, and limit analysis. It is structured into eight chapters, with each chapter containing numerous exercise questions. Chapter 1 provides an extensive introduction to continuum thermomechanics, emphasizing constitutive theories of inelastic deformation from the perspective of internal variables. The book aims to be self-contained and is well-suited for both educational and research purposes.This monograph by L. B.
