Examination of the coatings of coronary stents [PDF]

, 2006
In our study the main properties of coated coronary stents are shown, such as foreshortening, recoil, surface features and failures and the expansion properties. The types and the effects of active and passive coatings are introduced.

Dissipation measurements during ultrasonic fatigue tests

, 2013
The aim of this paper is to analyse the dissipation observed during dynamic fatigue loading at low stress range and high number of cycles. Infrared thermographic techniques were developed to estimate the mean dissipation per cycle. Results derived from tests performed at high loading frequency on pure copper specimens showed a drift of dissipative ...

On the orthotropic elasto-plastic material response of additively manufactured polyamide 12 [PDF]

, 2016
The mechanical response of polymers such as polyamide 12 (PA-12) manufactured through additive manufac-turing, is significantly affected by the layered manufacturing approach and the printer settings used during the creation of the parts.

Ultrasonic attenuation of a void-containing medium for very long wavelengths [PDF]

Ultrasonic longitudinal through-thickness attenuation in an isotropic medium due to scattering by randomly distributed voids is considered analytically. The attenuation is evaluated on the assumption of no interaction between voids.
