The book entitled "Introductory Solid Mechanics" is aimed to present the topics of first course on Solid Mechanics (Strength of Materials) at undergraduate level in various universities/institutes. The subject matter is presented chapter wise in an easily understandable style, and learning objectives are indicated at the beginning of each chapter. Large number of worked out problems are given in each chapter to enable the readers to grasp the subject effectively. In addition, at the end of each chapter, highlights containing important definitions, concept and formulae are presented followed by short questions and exercise problems.The first chapter of the book presents simple stresses and strains in which the basic concepts of stress and strain are explained with the discussion on elastic properties. The second chapter deals with the compound stresses and strains where the reader is exposed to analytical as well as graphical method of computing the principal and maximum shear stresses and their associated planes. Chapter three is fully devoted to the shear force and bending moment calculation of beams, whereas chapter four presents the bending stress and shear stress in beams due to their bending. The study of slope and deflection of beams is presented in chapter five where various methods of finding the slope and deflection of beams such as double integration method and moment area method are discussed. Chapter six deals with the study of torsion. The torsion formula is derived, and the combined effects of bending and torsion are presented. The last chapter deals with the analysis of thin cylindrical and spherical shells.For more details, please visit https://centralwestpublishing.com

This book consists of three parts, elasticity, fracture, and fatigue. Part I deals with elasticity and consists of four chapters. Chapter 1 introduces tensor notation. To help students become familiar with the use of tensors, coordinate transformation, stress transformation, Kronecker delta, principal stress, etc., are written in both tensor and unabridged forms. In Chapter 2, three-dimensional governing equations in elasticity are introduced in tensor notation. It includes the equilibrium equation, Hooke's law, the relationship between strain and displacement, traction vector, compatibility equations and Navier's equilibrium equations. Chapter 3 deals with two-dimensional elasticity. The difference between the plane strain state and plane stress state is stated, and the governing equations of each state are obtained from three-dimensional governing equations. In Chapter 4, Airy stress functions in Cartesian and polar coordinates are introduced. The transformation method between the governing equations in Cartesian coordinate and polar coordinator is also explained. Part II treats fracture and consists of three chapters. In Chapter 5, the difference between notch and crack, the concept, physical meaning, and importance of stress intensity factor, and theoretical and experimental plastic zone shapes and sizes at the crack tip are explained. In Chapter 6, the standard test method of plane strain fracture toughness is introduced. The fracture mechanics design method to prevent yielding and fracture is also explained. Chapter 7 deals with fatigue fracture. The standard test method of fatigue crack growth rate is briefly introduced. The difference between Paris' law and Forman's law is explained. How to search why a crack was developed in the structure and how to make fatigue crack growth retard are also introduced. Part III deals with fatigue subject and has only one chapter, Chapter 8. It explains why fatigue data have scattering band, how to get a constant hysteresis loop from random fatigue load, how to get fatigue life, and how to get an approximation of S- N curves in metallic and non-metallic materials.

Metal-organic frameworks (MOFs) are ideal porous candidates where judicial changes in their structure can bring in different chemical reactivity. In recent years, it has been amply demonstrated both experimentally as well as theoretically, the fine-tuning of geometrical stature can influence the physicochemical and chemical properties of MOFs. Such fine modulation at the molecular level would confer a new environment that could be utilized to solve numerous challenges in chemistry such as achieving desirable catalytic properties, facilitation of gas sequestration at ambient conditions, harnessing unprecedented optical/magnetic response, thermal properties, etc. To this end, the porous nature of MOF can host several molecules or can integrate with various molecules such as fullerenes, carbon nanotubes, carbon dots, dye, etc. to elucidate the fascinating chemistry occurring in the confined state. The reader of this book will gain an up-to-date account of what has been done in recent times by various researchers around the world. This book is a valuable reference for chemists, material scientists and engineers as well as researchers in both academia and industry. It is also a beneficial resource for postgraduate university students in chemical, polymer and materials disciplines, along with interdisciplinary streams to design his/her own research directions.
