Vibration Response of Steam Turbine Healthy and Cracked Blade under the Stress Stiffening and Spin Softening Effects
TL;DR: In this article , the vibration responses of the healthy and cracked blade under the influence of stress-stiffening and spin-softening have been studied and the three-dimensional finite element-based numerical analysis is carried out to study the blade's mode shape and natural frequencies and validated with the experimental modal analysis test results.

Mechanics of Laminated Composite Plates and Shells : Theory and Analysis, Second Edition
TL;DR: The use of composite materials in engineering structures continues to increase dramatically, and there have been significant advances in modeling for general and composite materials and structures in particular as discussed by the authors. But the use of composites is not limited to the aerospace domain.

On a curve veering aberration
TL;DR: In this article, the Ritz-Galerkin method is applied to the classical eigenvalue problem of the free vibration of a rectangular membrane, and it is shown that the behavior of curves which approach each other and suddenly veer away may be the result of approximation in the representation of physical reality.
