Improved Damage Assessment of Parchment.
Stitching of laminated composites is a proven way to improve damage tolerance and increase interlaminar fracture toughness.
The IDAP project, Improved Damage Assessment of Parchment 2002-2005, was funded by the EC under the fifth framework program: Energy, environment and sustainable development (EESD).
UHPFRC columns exhibited significantly higher blast resistance such as lower maximum deflection, improved damage tolerance, and higher resistance, compared with the reinforced SCC and NC columns.
Parametric studies were performed to investigate the effect of shape memory alloys for improving damage resistance of composite plate.
The need for further work has also been identified to provide a more robust technique to improve damage predictions.
To illustrate the top-down design approach these fundamental theories enable, potential future solutions are presented to design against these damages in order to improve damage tolerance.
The compression and buckling tests indicated that the pins have potential to improve damage tolerance of FML panels, since a less-catastrophic behavior was observed.
The effects of shape memory alloy thin films embedded in composite plates for improving damage resistance of composite structures under low velocity impact were investigated numerically.
For instance, including further information such as the logging techniques applied (conventional or reduced-impact logging), the local topography, or the forest structure would certainly have improved damage predictions.
Hybrid structures enable minimization of weight, improved damage tolerance in the joined structure, optimized matching of properties to design needs, and improved economy in basic material costs as well as the cost of fabricating difficult materials.
