Plates of polyethylene terephtalate (PET) were prepared by an injection-compression process such that the initial microstructure was almost completely amorphous. Specimens machined from these plates were subjected to plane-strain stretching experimen

La microscopie de force atomique a ete utilisee pour etudier la structure lamellaire d'echantillons massifs de polypropylene isotactique obtenus par intrusion. La microscopie de force atomique utilisee en tapping mode se revele etre un outil performa

Samples of poly(etherether ketone) (PEEK) were subjected to large plastic deformations under uniaxial tension and simple shear by means of a new video-controlled testing method at constant true strain rate. The “equivalent” stress-strain curves o

The low-frequency Raman scattering (2–200 cm −1 range) of poly(methyl methacrylate) (PMMA) specimens plastically deformed in pure shear is compared to that of non-deformed specimens. The main experimental feature is an excess of Raman scattering

The α- and β-spherulites in polypropylene (PP) were identified by direct observation in the scanning electron microscope after appropriate etching. The α-phase has a dark contrast while the β-phase is brighter. Results concerning the individual b

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

The aim of this work is to investigate the complex spherulitic structure of bulk polypropylene samples from direct scanning electron microscopy (SEM) observations of etched surfaces. Thick plates of isotactic polypropylene were moulded by intrusion.

A previous paper has shown how it is possible to determine the stress induced in a bilayered circular laminate glass-resin under various conditions with a nondestructive method. In this paper a more precise mathematical analysis which allows predicti

A nondestructive method is proposed to analyze the internal stresses of a circular bilayered laminate glassresin. It is based on the measurement by optical interferometry of small deformations of the laminate under the influence of temperature, time,
