Beneficios industriales derivados del empleo de galgas extensométricas bien contrastadas
Las galgas de película metálica bien contrastadas ofrecen numerosas ventajas con respecto a las tecnologías alternativas, en opinión del Dr. Ing. André Schäfer, de HBM.
Successfully compensating for lead resistances
If measuring points are not directly accessible, the measuring instruments need to be connected using long cables. The disadvantage: The lead resistance can negatively affect the measurement. Various types of strain gauge...
Metrological recording of deformation development in ultra-high performance concrete (UHPC) in a triaxial test cell
This article shows that by using a "triaxial cell" test rig, it is possible to determine the triaxial strengths for both static and dynamic loadings.
Using statistical techniques to validate field test data for fatigue analysis
This paper describes some statistical techniques for taking measured data and projecting what the expected time history and resulting fatigue damage would be if test data were collected for much longer times.
Early warning of damage to wind turbine rotor blades
Suitable sensor technology must be employed to detect the damage to wind turbine rotor blades early enough, and minimize the economic consequences. The sensors must be able to withstand tough ambient conditions and must...
Improved Strain Gage for Residual Stress Analysis Using the Hole Drilling Method
In the following it will be demonstrated that the new HBM symmetrical rosette design will significantly reduce the errors in the measurement and will allow much more reliable stress results.
Measuring surface strain using flexible fiber-Bragg strain gauges
Our comprehensive article provides basic knowledge on the topic: Everything you need to know about measurement using optical strain gauges: From technological background information through calibration of interrogators and...
Instalación de bandas extensométricas sobre materiales plásticos reforzados con fibra
La instalación de bandas extensométricas sobre materiales plásticos reforzados con fibra presenta ciertas particularidades que la diferencian de las instalaciones habituales:
Selección y tipos de bandas extensométricas
De acuerdo con la tarea de medición, las bandas extensométricas se seleccionan según su diseño, serie, modo de conexión, adaptación a la respuesta de temperatura, longitud de la rejilla de medición y resistencia electrica. El...
