Stiffness and energy degradation of wood frame shear walls
Canadian Journal of Civil Engineering, 1998Tests have been conducted on wood frame shear walls to characterize the degradation of stiffness and energy dissipation that occurs under cyclic loading. A total of eight walls were tested, four sheathed in plywood and four sheathed in oriented-strand board.

Stiffness degradation in granular materials due to chemical dissolution
Géotechnique Letters, 2019This study proposes a continuum model on stiffness deterioration in reactive granular materials due to chemical weathering. In chemo-mechanical degradation, the packing of the granular material varies as the particle size reduces. A set of chemically treated granular specimens, weathered up to different degrees of dissolution, were prepared ...

Identification of stiffness degradation in structures using wavelet analysis
Construction and Building Materials, 2005Abstract An approach for structural health monitoring (SHM) and damage detection using a wavelet based time-frequency technique is presented here. The characteristics of dynamic responses of structures are studied by wavelet analysis. Inferences are drawn from the wavelet coefficients obtained.

Lamb wave assessment of stiffness degradation in fatigued composites
AIP Conference Proceedings, 2000A Lamb wave scanning system that measures the elastic properties of a material was used to characterize fatigue damage in composites. The Lamb Wave Imager™ (LWI) uses a pulse/receive technique that excites a flexural Lamb mode and measure the time-of-flight over a wide frequency range. Given the material density and plate thickness, the bending and out-
