What are some challenges or limitations of applying linear damping theory to nonlinear or hysteretic systems?
Linear damping theory is a widely used approach to model the energy dissipation in mechanical systems subjected to oscillatory or dynamic loads. However, it is not always accurate or applicable for systems that exhibit nonlinear or hysteretic behavior, such as rubber, plastic, or metal alloys. In this article, you will learn about some of the challenges or limitations of applying linear damping theory to nonlinear or hysteretic systems, and some possible alternatives or solutions.
