When dealing with isotropic polymer, it is easy to characterize the linear viscoelasticity in the lab via dynamic mechanic analysis in tension, torsion. What about for a transversely isotropic material such as a carbon fibers reinforced polymer? Actually, one may find out that it is not possible to directly assert any of the five parameters […]

Comparison between two fracture tests, SENB vs. DCDC applied to acrylate polymers
We have compared the mode I opening critical energy release rate (GIc) measured using the single edge notch bending test and double cleavage drilled compression test on an elastic fragile PMMA and a bulk viscoplastic acrylate used as a glue for wind turbine blades. The study details the experimental procedure, for the crack initiation and […]
Damage phase-field approach vs. Cohesive zone model for double cleavage drilled compression fracture test
The double cleavage drilled compression (DCDC) test has been introduced for glass but also extended to test polymer. It is a slender prismatic specimen with a hole in its middle and cracks that are initiated at both poles. It is interesting because the loading is uniaxial compression and the cracks are submitted to opening mode […]
