This study presents an experimental investigation of the recently established generalized linear sampling method (GLSM) for non-destructive evaluation damage in elastic materials. To this end, ultrasonic shear waves are generated a prismatic slab charcoal granite featuring discontinuity interface induced by three-point bending (3PB). The interaction probing with 3PB-induced gives rise to transi...

In the present work, structure health monitoring (SHM) of welded steel pipes was used to diagnosis their state via vibration based damage detection techniques. The dynamic quantities such as Frequency Response Functions (FRFs), mode shapes and modal parameters from structural vibration to detect damage were measured, set on linear averaging mode, with a maximum frequency of analysis of 3.2 kHz....

The differential evolution indicators, recently introduced for imaging mechanical in highly scattering solids, is examined a laboratory setting with the focus on spatiotemporal tracking of an advancing damage zone elastic specimen. To this end, prismatic slab charcoal granite quasi-statically fractured three-point-bending (3PB) configuration, while ultrasonic shear waves are periodically genera...

most published results about the characteristics of niti wires are based on the mechanical laboratory tests on the as-received wires.the purpose of this study was to investigate the effect of saliva on load-deflection characteristics of superelastic niti wires.in this experimental study, 15 wires of three kinds of superelastic niti wires (sentalloy, force i and truflex) were prepared. five spec...

The inconsistencies accompanied with material properties tipically cause the rise of delamination risk in composites made of different types of glass and crabon fibers. In this study, the delamination of a composite beam reinforced with a carbon layer under bending load is investigated. To this end, a small piece of a wind turbine blade root in the form of a heterogeneous laminated plate is sim...
