This book provides selected papers presented at the 1st International Conference on Mechanics of Solids, held in Porto, Portugal, November 3-4, 2022.The book focuses on the mechanics of deformable solids, dynamics of particles and rigid bodies. Topics like mechanical behaviour of materials, mechanics of composite materials, plasticity, fracture mechanics, and optimum design methods are covered. This volume provides the latest trends related to mechanics of solids and appeals to researchers and practitioners across the broad spectrum.
