[null,null,null,"Sommario/riassunto","This book provides a detailed overview of the theory of analytical and experimental modal analysis and its applications.  Modal Analysis is the processes of determining the inherent dynamic characteristics of any system and using them to formulate a mathematical model of the dynamic behavior of the system.  In the past two decades it has become a major technological tool in the quest for determining, improving and optimizing dynamic characteristics of engineering structures.Its main application is in mechanical and aeronautical engineering, but it is also gaining widespread use in civi"]
