This study proposes an analytical model for vibrations in a cracked rectangular plate as one of the results from program research on vibration based damage detection aircraft panel structures. particular work considers isotropic plate, typically made aluminum, and containing crack form continuous line with its center located at parallel to edge plate. The is subjected point load surface three different possible boundary conditions, examined detail. Galerkin’s method applied reformulate...
A method for damage localization based on the phased array idea has been developed. Four arrays of transducers are used to perform a beam-forming procedure. Each consists nine placed along line, which able excite and register elastic waves. The 0 Lamb wave mode chosen method. in such way that angular difference between them is 45° rotation point middle transducer, common all arrays. tested square aluminium plate modeled by Spectral Element Method. Two types were considered, namely...
In this article, the effect of polycaprolactone nanofibers on dynamic behavior glass fiber reinforced polymer composites is investigated. The vibratory composite beams in their pristine state (without any nano modification) and same modified with fibers considered experimentally. experimental results show that incorporation increases damping; however, it does not significantly affect natural frequencies. Additionally, paper analyses impact fiber/epoxy composites. This has already been...
The problem for measurement point selection in damage detection procedures is addressed. concept of average mutual information applied order to find the optimal distance between points. idea select points such a way that taken measurements are independent, i.e. do not `learn' from each other. can be utilized as kind an autocorrelation function purpose. It gives amount two Thus minimum will provide with independent measurements. use first nonlinear dynamics. proposed approach demonstrated on...
In recent years, triboelectric nanogenerators (TENGs) are used to harvest mechanical energy from ambient environment. These devices convert energies (e.g. vibrations, breathing-driven, impacts or human body motions) into electricity based on the effect. Furthermore, some TENGs can be successfully employed as self-power active sensors because electric response TENG is proportional magnitude of motion. This study report design and development a novel nanogenerator, its potential application...
This paper considers a vibration-based damage assessment approach which is based on the general idea for signal cross-correlation. Here method demonstrated and validated composite laminate beam it applied purposes of delamination in structures. The uses two measures cross-correlation between vibration signals measured different points structure order to diagnose delamination. linear as well new measure nonlinear cross-correlation, mutual information, are introduced assessment. comparison...
