The book "Vibrations of Plates and Shells with Attached Concentrated Mass" offers a comprehensive investigation into the mathematical modeling of dynamic problems in elastic and viscoelastic plate and shell systems. It focuses on the application of variational methods to address specific challenges associated with point connections and concentrated masses. The authors, Ozod Rajabov, Ismoil Safarov, and Maqsud Akhmedov, present various calculation methods that concentrate on the dynamic behavior of elastic rectangular plates and rotationally symmetric shells. This specialized book is aimed at professionals and students seeking a deeper understanding of the theoretical and practical aspects of vibration analysis in engineering structures.
