This paper presents a methodology for predicting vibrations produced by underground railways through 2D FEM numerical models formulated in the time domain. The numerical approach is based on the application of train loads as dynamic displacements on the r... see more

Synthesis by mechanochemical activation route and optimisation for power harvesting properties of nano-structured Pb0.98La0.02(NiSb)0.05[(Zr0.52Ti0.48)0.995]0.95O3 [La-PNS-PZT] ferroelectric ceramic composition has been carried out and reported here for t... see more

Due to the development of Bogota (main city of Colombia) and to its increase of population, transport systems have been constructed in the last decade. Although these systems increase the well-being of the citizens, the traffic could generate vibrations p... see more

The object of research is the process of propagation of vibrations from technological equipment to the metal structures of a building. One of the problems in the inspection and monitoring of construction objects is the assessment of the vibrational impact... see more

The paper reports an algorithm to analytically solve one of the problems in the mechanics of elastic bodies, which is associated with studying the natural vibrations of a composite two-stage plate whose concave part is smoothly aligned with the part of a ... see more

The problem of wind turbines aeroelastic rotor vibrations calculation is considered. It showsthat the analysis of the elastic blade aero stability in this case differs from the classical approach

The formal procedure for calculations of longitudinal and torsion vibrations of the multispan beams with continuous mass distribution on the basis of the method of start parameters, associated matrices and elements of mathematical logic is proposed.
