This volume of 'Engineering Innovations' presents a collection of research articles on cutting-edge engineering topics. It covers various engineering challenges and innovations, including the simulation of stress intensity factors and J-integrals on UIC 54 railway failures using fracture mechanics, the behavior of thin-walled cylinders with ribs for energy absorption, and topology optimization of motorbike footrests using finite element methods. The book aims to provide insights into the latest developments in engineering design and analysis, targeting professionals, researchers, and students in the field of mechanical and industrial engineering. The studies utilize advanced simulation tools like ANSYS to explore issues such as fatigue failure in railway tracks due to repetitive loading and defects, offering solutions for improving structural resilience and performance.

This unique, first of its kind, book offers an integrated treatment of the atomistic-continuum behaviours of single and interacting microdefects under elasto-static loading. These microdefects may take the form of nanocracks, microcracks, microvoids, inclusions, and inhomogeneities. Professor Meguid elucidates the subject matter using novel treatment that offers a fresh look at molecular and continuum mechanics, imperfections in solids, the Griffith crack, modes of failure and diagnostics at varied length scales, LEFM and multiscale modeling of interacting microdefects. Providing a range of perspectives from theory and applications, this book is ideal for college seniors, graduate students, practicing and research engineers interested in failure analysis, diagnostics and prevention. Fosters greater understanding of fracture mechanics concepts at varied length scales; Adopts a unique approach combining atomistic and continuum behaviours of interacting nano/microdefects; Empowers conceptual interpretations of content through a thorough treatment of the subject.
