TL;DR: A monitoring scheme is introduced which shows the different steps necessary to relate the output of an embedded FBG to the strain of the structure in which it is embedded, and temperature compensation methods which should not be ignored in terms of in-situ measurement of strains with fibre Bragg gratings.

TL;DR: Results evidence the relevance of using microstructured optical fibers for structural integrity monitoring of composite material structures and obtain a sensitivity to transversal strain that exceeds values reported earlier in literature by one order of magnitude.

TL;DR: In this article, the entire visco-elasto-plastic response is determined based on experimental data obtained through tensile, compression, shear and relaxation testing, and ultrasonic non-destructive testing is proposed as an alternative to conventional testing for the derivation of the elastic properties of this material.

TL;DR: In this article, a modified approach accounting for higher-order effects and yielding significantly improved accuracy is presented, which allows for a more accurate determination of flexural rigidity, and enables the more accurate simulation of composite forming processes.

TL;DR: In this article, the first-ever implementation of an inverse modeling technique on the basis of a genetic optimization scheme in order to extract quantita- tive information from a pulsed ultrasonic polar scan (P-UPS) was reported.
