EXPERIMENTAL METHODOLOGY TO DETERMINE THE ABSORBED ENERGY IN AN AERONAUTICAL STRUCTURE UNDER IMPACT LOADS USING DIGITAL IMAGE CORRELATION

Elías López Alba (Universidad de Jaén) Ángel Molina Viedma (University of Jaén) Francisco Alberto Díaz Garrido (University of Jaén)

 

In this work and energy balance for an aeronautical structure under impact loads were evaluated. An experimental methodology was developed to quantify the transformation of the transmitted energy into the different damages produced at the specimens.

HIGH SPEED DIGITAL IMAGE CORRELATION FOR MODE SHAPE MEASUREMENTS ON A CARBON FIBER CURVED PANEL

Ángel Molina Viedma (University of Jaén) Luis Felipe Sesé (University of Jaén) Elías López Alba (Universidad de Jaén) Francisco Alberto Díaz Garrido (University of Jaén)

 

In this paper, Digital Image Correlation, DIC, and High Speed Cameras, are applied to determine the mode shapes [2] of a carbon fiber aeronautical panel. results show full-field displacements corresponding to each mode shape over the whole surface.

ADHESION TEST OF RESIN-INFUSED BASALT FIBERS FOR WIND ENERGY APPLICATIONS

Wilko Happach (RWTH Aachen University) Davide Pico (RWTH Aachen Univeristy) Alexander Lüking (RWTH Aachen University) Gunnar Seide (RWTH Aachen University) Thomas Gries (RWTH Aachen University)

 

Rotor wind blades are principally made of E-glass fibers reinforcement into an epoxy resin. This fibers have already reached the limit of their mechanical properties, therefore new materials like Basalt fibers are needed.

NUMERICAL SIMULATION OF MECHANICAL BEHAVIOR OF A HIGH-VOLTAGE COMPOSITE CABLE FOR OFFSHORE WIND-ENERGY

Fouad Ech-Cheikh (CEA) Raj Jyoti Das (IFSTTAR) Monssef Drissi-Habti (IFSTTAR) Nicolas Ravot (CEA) Fabrice Auzanneau (CEA)

 

In this study, a simple straight ”1+6” strand is modelled as a copper conductor and the relationship between mechanical loads to which conductors are subjected to and its mechanical responses is addressed.

FUNCTIONALIZED ORMOCER®-BASED RESINS AS BASIS FOR HIGHLY AESTHETIC, LOAD-STABLE AND BIOCOMPATIBLE DENTAL MATERIALS

Jeannette Hoffmann (Fraunhofer ISC) Herbert Wolter (Fraunhofer ISC) Somchith Nique (Fraunhofer ISC)

 

Biocompatible dental hybrid composites well-adjusted to mechanical/optical properties of natural teeth (dentine/enamel) realized by functionalized ORMOCER® resins along with adapted particle systems represent an excellent material for e.g. crowns.
