Glass transition and physical aging of PLA, PLA/ZnO_r and PLA/ZnO_s nanocomposites The impact of the two types of nanoparticles on the polymer re- laxation phenomena was probed by

In order to evaluate the effect of temperature and dynamic strain aging on the fatigue life, simple tensile tests were carried out on the material at 350C, which corresponds to the high

The tests have shown a reduction in the cutting force, and have highlighted the impact of laser assistance on the integrity surface roughness, appearance, residual stress and the tool

Hyperbola method, PDF contour of the estimated locations for the impact of size 20mm and the actual damage location white cross.. The performance quantification is done thanks to the

The cold rolled CR and cold rolled aged CR/573K‐0.6ks/WQ and CR/573K‐7.2ks/WQ specimen revealing a strong hardening under tension have quite close fatigue life performances under 3%, 2%

In the case of an impact on an incompressible liquid, the peak pressure is proportional toρ V0 c2, withVcthe expansion velocity of the surface contact, see Cointe and Armand, 1987;Zhao

Introduction Materials & methods Results and discussion Conclusion ParisTech Centre de Cluny Sample Preparation Type B : sapwood veneer of 3 mm • Making 7 layer of veneers •

This provides a first explanation of the fatigue life reinforcement or the crack propagation resistance increase for non- relaxing conditions: by enabling strong secondary crack
