摘要:Abstract(#br)An exciting paradigm in the ongoing development of materials is the development of auxetic mechanical metamaterials, which can be flexibly designed to exhibit a unique range of physical and mechanical properties. Inspired by nonuniform or nonhomogeneous metamaterials...

摘要:Abstract(#br)This paper presents dynamic buckling analysis for a functionally graded graphene nanoplatelets reinforced composite (FG-GPLRC) arch subjected to a step central point load at its center. The arch is composed of multiple composite layers reinforced with graphene nanopl...

摘要:Abstract(#br)This study presents a two-stage Bayesian finite element model updating procedure by using acceleration response measurements obtained from multiple setups. In the presented methodology, parametric uncertainties for the modal parameters are estimated by using the Baye...

摘要:Abstract(#br)The analytical solution for the one-dimensional acoustic field in a straight duct with arbitrary mean temperature gradient and mean flow has been recently derived based on an adapted WKB approximation (J. Li, A.S. Morgans, J. Sound Vib. 400 (2017) 248–269 [12])....

摘要:Abstract(#br)Abradable liner materials are often used in turbine engines between the compressor blade tips and the casing. The abradable liner serves as a partially sacrificial material to improve the overall engine efficiency by creating a tight seal, minimising gas flow leakage...

摘要:Abstract(#br)As studied by the authors in a previous work, applying topology optimization to minimize overall dynamic response of structures under time-harmonic loads may present serious drawbacks. It happens e.g. for an excitation frequency above the first resonance of the initi...

摘要:Abstract(#br)Compared with the direct force measurement of cables, dynamic modal testing is more economic and applicable in engineering for monitoring the stiffness change of cable net structures caused by pretension deviation. Normally, it is sufficient to detect the variation o...

摘要:Abstract(#br)This paper outlines a complete methodology for designing a control system that reshapes the dynamic response of the flexible structure to robustly match the dynamics of a given adaptable reference model. The procedure was experimentally verified on a setup developed ...

摘要:Abstract(#br)Tyre cavity noise is a narrow band, high amplitude resonance which occurs when the sound waves in a car tyre oscillate back and forth in one direction with a low loss factor. Manufacturers add damping materials to vehicles, due to the difficulty of reducing the sourc...
