Identification of structural damage in flexible structures using system norm and neural networks
(2006-12-01)
Nowadays there is great interest in damage identification using non destructive tests. Predictive maintenance is one of the most important techniques that are based on analysis of vibrations and it consists basically of ...

Damage detection in uncertain nonlinear systems based on stochastic Volterra series
(2018-01-01)
The damage detection problem in mechanical systems, using vibration measurements, is commonly called Structural Health Monitoring (SHM). Many tools are able to detect damages by changes in the vibration pattern, mainly, ...
Induction of glandular and non-glandular trichomes by damage in leaves of Madia sativa under contrasting water regimes
(Elsevier, 2008)
Plant traits may play multiple functional roles simultaneously. Leaf trichomes have been related to resistance against herbivores as well as to enhanced water economy in the plant. In a greenhouse study, we evaluated the ...
Static response of asymmetrically damaged metallic strands: Experimental and numerical approach
(Elsevier Ltd, 2018)
In this study, the effect of the presence of broken wires (damage) asymmetrically distributed on metallic strands surfaces on their static response is assessed. To this end, a general mechanical model for multilayered ...
Improvement of damage-assessment results using high-spatial density measurements
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-06)
Model-based damage assessment is based on measuring the distance between experimental and analytical results. In practice, measurements yield only partial mode shapes with respect to the total degrees of freedom present ...
Genistin and quinolizidine alkaloid induction in L. angustifolius aerial parts in response to mechanical damage
(Taylor & Francis, 2013)
Lupinus species are commonly used as annual forage and for grain production. They are considered alternative crops to soybean due to their adaptation to cool environments and dry soils. The present study is an analysis of ...
An Anisotropic Model of Damage and Unilateral Effect for Brittle Materials
(World Acad Sci, Eng & Tech-waset, 2007-01-01)
This work deals with the initial applications and formulation of an aniscitropic plastic-damage constitutive model proposed for non-linear analysis of reinforced concrete structures submitted to a loading with change of ...
Mechanical properties of irradiated nanowires - A molecular dynamics study
(Elsevier Science, 2015-12)
In this work we study, by means of molecular dynamics simulation, the change in the mechanical properties of a gold nanowire with pre-existing radiation damage. The gold nanowire is used as a simple model for a nanofoam, ...
Base Cut Quality and Productivity of Mechanically Harvested Sugarcane
(Springer, 2020-04-01)
This experiment aimed to assess the damage caused in the sugarcane ratoon by the wear of the base cutter blades over 5 h of effective harvester work and the influence of the damage on the growth and productivity of the ...
