This book presents select proceedings of the 2nd International Conference on Innovative Materials, Manufacturing and Advanced Technologies (IMMAT'2022), held in Sousse, Tunisia, on October 27-29, 2022. The covered topics include theoretical, experimental and technological works and its application in various challenging domains like materials sciences, mechanical design, manufacturing, environment and heat transfer. The volume provides an overview of innovations and technological advances in mechanical engineering. Given the selected and peer reviewed papers, it will be a useful resource for practitioners working on cutting-edge topics in several areas related to the mechanics such as mechanical behavior, material-process interaction, fatigue behavior, tribological behavior of surfaces, manufacturing, organization and optimization of production processes, additive manufacturing processes, renewable energy, design of lightweight components, robotics and industry 4.0. This book is intended to serve researchers, engineers and professionals working in the fields of material and mechanical engineering.
