Experimental assessment of fatigue damage mechanisms in [04/90n]s laminates using carbon-epoxy ultrathin plies
(2021-06-25)
The damage mechanisms of cross-ply laminates under fatigue loading have been deeply studied during last years. In this work, the experimental assessment of two different cross-ply laminates under T-T loading (stress ratio ...

Ballast shear effects on the dynamic response of railway bridges
(Elsevier, 2022-12-01)
Single-track railway bridges are susceptible of experiencing high levels of vertical acceleration on the deck that may be dangerously accentuated at resonance. This is especially critical for short-to-medium span simply ...

Caracterización del daño de acuerdo a la mecánica de la fractura en laminados 0/90
(Grupo Español de Fractura, 2004)
Los laminados 0/90 de materiales compuestos fibrosos cuando son sometidos a carga en la dirección de las fibras a cero grados, presentan un daño consistente en la aparición de grietas transversales en las láminas a 90 ...

Estimating robust optimum parameters of tuned mass dampers using multiobjective genetic algorithms
(Víctor Compán Cardiel [etc.], 2015)
Tuned mass dampers (TMD) are a well-known control device widely used to control the vibratory problem originated by the pedestrian action on footbridges. The main purpose of this study is the robust multi-objective ...

Analysis of the State of Stresses and Plastic Strains during the Necking Process in Ductile Steels
(Elsevier, 2013)
In steel, the knowledge beyond the yield strength elastic is of the utmost importance because of the large plastic strain that take place both at the time of the breakage and multiple conformation processes involving a ...

Damage detection in beams from modal and wavelet analysis using a stationary roving mass and noise estimation
(Wiley, 2018-04)
This paper uses the Continuous Wavelet Transform Analysis on mode shapes for damage identification. The wavelet analysis is applied to the difference in the mode shapes between a healthy and a damaged state. The paper also ...

“Kinking” de grietas transversales de interfase entre fibra y matriz de materiales compuestos fibrosos
(AEMAC (asociación española de materiales compuestos), 2003)
Los materiales compuestos fibrosos pueden fallar ante cargas transversales a la dirección de la fibra. Esta rotura se conoce como fallo de la matriz o fallo entre fibras y se caracteriza por la aparición de grietas en ...
