Damage to poly(vinylidene fluoride) was studied under uniaxial tension testing at different temperatures and strain rates. A satisfactory accuracy was reached with an original procedure for the assessment of the principal strains and volume strain. T

Poly(vinylidene fluoride) (PVDF) was subjected to a creep test performed at constant true stress. The use of an original method to control and adjust, in real time, the stress allowed the assessment of volume changes occurring during the test. The ad

The influence of high-pressure recrystallization on the semi-crystalline microstructure and on the mechanical behavior of ultra-high molecular weight polyethylene (UHMWPE, M v 5 10 6 g/mol) is investigated. This process involves polymer re-melting at

This paper discusses the time-dependent mechanical response of poly(methyl methacrylate) (PMMA) and polystyrene (PS) subjected to a shallow indentation made by a 750 µm radius steel ball at 25 °C. The penetration depth was measured as a time-respon

We report an extensive study of dynamic friction at nonlubricated multicontact interfaces between nominally flat bodies, rough on the micrometer scale, made of identical polymer glasses. This work, which complements a previous study of static frictio

Accidents occurring during intubations often originate in the mechanical interaction between the tube and the upper airways. A review of these accidents, including their possible complications, shows that they are mainly due to the forces exerted by

Shear experiments were performed on epoxy network specimens aged at different temperatures and strain rates. The experiments showed an increase of yield stress, σ y , versus the aging time in the glassy state. Two aging regimes, with a fast and slow
