Application of ultrasonic vibrations for minimization of the accumulation of limescale in steam irons
The accumulation of limescale in steam irons can significantly reduce the ironing efficiency. It is this problem that inspired us to introduce ultrasonic vibrations to irons in order to minimize limescale accumulation. ...
Detection of air leakage into vacuum packages using acoustic measurements and estimation of defect size
Air leakages in food and ingredient packages which are sealed in vacuum environments may cause a marked deterioration of the product, leading to a loss of functionality. Manufacturers of such products have very stringent ...
A new triangular composite shell element with damping capability
This paper presents a new triangular composite shell element with damping capability. Formulation of the composite triangular shell element is based on stacking individual homogeneous triangular shell ele- ments on top of ...
Characterization of viscoelastic materials using free-layered and sandwiched samples: assessment and recommendations
(Polish Physical Society, 2015-04-01)
Viscoelastic materials are widely used in many applications in practice. However, determination of the elastic and damping properties of these materials is quite difficult in the sense that the identified results may contain ...
