Uniaxial and plane strain compression experiments are conducted on amorphous poly
(ethylene terephthalate)(PET) and poly (ethylene terephthalate)-glycol (PETG) over a wide …

A constitutive model is developed to capture the rate-dependent stress–strain behavior of an
amorphous polymer (poly (ethylene terephthalate)-glycol (PETG)) at temperatures in and …

PET and PLLA were cold crystallised at various times and the two polymers were studied by
differential scanning calorimetry (DSC), dielectric spectroscopy (DS) and thermally …

The Vicat softening temperature, melt and crystallization behavior, as well as the mechanical
properties of polylactic acid (PLA)/nucleating agent (TMC-328) composites with different …

Poly (lactic acid)(PLA) is the most traded biodegradable and biobased material. It is largely
used as eco-friendly substitute of conventional plastics. Nevertheless, one of the main …

The 21st century offers vast challenges for researchers all around the globe, especially
regarding the effective use of sustainable polymers and their materials for different …

In this work, we determined the Cooperative Rearranging Region (CRR) average sizes at
the glass transition temperature according to Donth's approach. From Temperature …

This research focuses on the definition and application of a characterization methodology to
determine the characteristics of fused deposition modeling 3D printing materials …

In most cases, a three-phase model consisting of crystalline domains surrounded by rigid
amorphous areas dispersed in the mobile amorphous phase is required and eventually …

In this paper, the effective elastic properties of semi-crystalline polymers are computed
through a new three-phase model. The formulation of this approach is based on recent …
