How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
A 2D numerical model for the solution of the eddy-current induction problem in non-linear hysteretic media is presented. The convergence of the iterative algorithm for the inversion of the non-linear operator is discussed. The numerical results are compared with simulations carried our using a commercial finite elements solver. Finally, an experime...
In the context of mid- and high-frequency problems in acoustics and vibrations, the modelling of complex systems generates several difficulties, partially related to the large number of degrees of freedom in the discretised model. That makes the problem computationally heavy and very sensitive also to uncertainties in the data. For this reason, in...
One of the most challenging field in structural dynamics is related to high frequency vibrations. These problems are born in vibration-acoustic analysis, with special interest in automotive or aerospace industry, where the capability of prediction of the noise response of the vehicle and the enhancement of its vibro-acosutic performance has a strat...
The first part of the paper deals with an extension of the classical Rivlin's solution of the torsion problem of a neo-Hookean pipe. The second part concerns a study of the passive torsional deformation processes in a fibre-reinforced cylindrical dummy of the beating heart. Especially, the dependence of the torsional and volumetric stiffness of the...
We study the mechanical response of a helically wound fiber-reinforced incompressible axisymmetric structure under torsion and compare it with the response turning out from the classical Rivlin solution of the torsion problem of a neo-Hookean pipe.
Modeling of soft tissues is a modern trend of investigation in the field of biome-chanics. This contribution involves demonstration of implemented non-linear elastic steady problem with some special results of numerical experiments. We will focus on hyperelastic nearly incompressible transversaly isotropic materials where the homogenous matrix will...
