The book entitled “Contemporary Engineering Applications Focused on Design, Materials and Manufacturing” addresses modern engineering practices from an integrated perspective built around three main pillars: design, materials and manufacturing processes. The chapters cover a wide range of topics, including Industry 4.0 and smart production systems in manufacturing, advanced machining processes, additive manufacturing applications, design and strength analyses based on the finite element method, innovative material use in machine elements, and recent developments in the field of biomaterials. In this way, both the theoretical framework and application-oriented examples are presented together for various engineering disciplines.

The book first discusses the digitalization of production environments, data-driven decision-making processes, and the flexibility, efficiency and sustainability dimensions of smart manufacturing systems. This is followed by experimental and analytical investigations of advanced processes such as ultrasonic-assisted drilling in the context of machining. The chapter dealing with the analysis of structural components produced by additive manufacturing using the finite element method demonstrates how design, material selection and manufacturing can be integrated through numerical approaches. Subsequent chapters examine innovative material applications in gear systems, focusing on engineering criteria such as mechanical performance, service life, weight and cost; finally, recent progress and future research directions in biomaterials are discussed through the example of bioactive glasses.

This book is intended to serve as an up-to-date, interdisciplinary and application-oriented reference for undergraduate and graduate students, academics and engineers in industry. Through comprehensive literature reviews, experimental studies and numerical analysis examples, it provides a concrete framework for understanding current trends in design, materials and manufacturing processes.
