Numerical modelling of some vocal folds (VF) pathologies can be realized by varying properties of VF layers. The aim of this paper is to show how damping of superficial lamina propria (SLP) affects vowel production in the finite element (FE) model of the VF self-sustained ...

The use of a high-speed water jet is one of the modern technologies for cutting and machining the material. High efficiency can be achieved by either by increasing the operating pressure or by using a non-stationary mode created by an ultrasonic generator. The use of ultr...

The dynamical systems describing general non-linear structures represent an interesting and demanding topic in various branches of engineering. This regards the both cases of mathematical and experimental models or an analysis of results from measurements in situ. In case of a complex b...

Machining processes are invaluable in many industrial branches. Calculation of the cutting forces is important for quality prediction of the machined surface. The cutting forces are usually expressed and manipulated in a certain coordinate system. So long the geometry of the cutting pro...

Various friction models were formulated to describe such a complex and naturally nonsmooth phenomenon. Generally, there are two categories of these models - static and dynamic. Static models describe friction phenomenon via friction characteristics governing the dependence of friction force on&#x...

The paper deals with 1D finite element modelling of a turbine blade. The proposed finite element has only 16 degrees of freedom (DOF) and enables to achieve a complex model of turbo-machine with a relatively small DOF number, more details will be described in the article....

Fused filament fabrication (FFF) is a type of extrusion-based additive manufacturing technique also known as fused deposition modeling (FDM) or 3D-printing. It is possible to use the process of additive manufacturing for manufacturing of prototypes and also the final products. It is wid...

The term of Hybrid Electric Vehicle (HEV) represents the vehicle as a general mechanical system which cannot be structurally modified (for example by a different type of engine), but the modification from point of view the driving processes can be done by using a suitable ...

This paper deals with aeroelastic (flutter) analysis of an aircraft with unconventional wing structure, which is specific by the installation of wing-tip tanks. The subjected aircraft is twin wing-mounted tractor turboprop commuter aircraft for 19 passengers, with a wingspan of 9.6 m an...

The aim of this work is the development of an interface between CFD software FlowPro and computing environment Matlab. FlowPro and Matlab coupled with the aid of the interface can be used to simulate complex problems such as fluid-structure interaction (FSI) problems. The fluid...

Fatigue life assessment of said bridges can be based on fully probabilistic philosophy. The loading just as response history should be taken into account and a fatigue criterion based on the amplitude interpretation should be used. Design of structures issues from the requirements ...

The most important parameters of the member are: the shear parameter ?, the member parameter ?, the parameter ?cr and amplification factor kII (MII = kII MI).
