Correction Criteria of Finite Element Modeling in Structural Dynamics

Mai Tong, +2 more
- 01 Apr 1992 - 
TL;DR: In this article, the authors carried out a comprehensive evaluation of model corrections by incorporating both analytical properties and numerical criteria, and proposed a correspondence rule of complex damping ratio to avoid this problem.

Joong Hyeok Lee, +2 more
- 01 Dec 2019 - 
TL;DR: In this article, a mode pair extraction method for a bell-type structure that employs a generated beat response signal is presented, which requires only the beat response measured at two points on the circumference.

Modal analysis of non-diagonalizable continuous systems with application to wind turbine blades

Xing Xing
TL;DR: In this paper, an approach for analyzing the complex modes of continuous systems with non-modal damping is presented, in which the assumed modes are applied to discretize the eigenvalue problem in state variable form, to then obtain estimates of the natural frequencies and state-variable modal vectors.
