About Book

Solid mechanics is the branch of continuum mechanics that studies the behaviour of solid materials, especially their motion and deformation under the action of forces, temperature changes, phase changes, and other external or internal agents. Several types of solids can be distinguished according to their mechanical behaviour. Solid mechanics is fundamental for civil, aerospace, nuclear, and mechanical engineering, for geology, and for many branches of physics such as materials science. It has specific applications in many other areas, such as understanding the anatomy of living beings, and the design of dental prostheses and surgical implants. Solid mechanics has many applications. Natural phenomena involving solid mechanics are studied in geology, seismology, and tectonophysics, in materials science and the physics of condensed matter, and in some branches of biology and physiology. This book is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of solid mechanics. It will discuss various aspects of particle-in-cell method, semisolid processing, continuum mechanics, drying mechanism, mechanochemical syntheses, lipid, stir-welding process and finite element methods. It takes some examples that cover the most relevant methods in specific applications to some materials and giving a little inside into the physics of the techniques involved. Some of the diverse topics covered in this book address the varied branches that fall under this subject area. The topics discussed are of utmost significance and bound to provide incredible insights to students. The book is appropriate for those seeking detailed information in this area.
