Strain hardening behavior of HDPE geomembranes [PDF]

E3S Web of Conferences, 2023
The strain hardening behavior is a good measure for the stress cracking resistance of HDPE geomembranes. Influences of the testing parameters temperature and cross head speed on the strain hardening modulus in material testing of PE were quantified.

Human Population Density is a Poor Predictor of Debris in the Environment

Frontiers in Environmental Science, 2021
There have been a variety of attempts to model and quantify the amount of land-based waste entering the world’s oceans, most of which rely heavily on global estimates of population density as the key driving factor.

Single-sided NMR for the measurement of the degree of cross-linking and curing [PDF]

Journal of Sensors and Sensor Systems, 2018
The degree of cross-linking and curing is one of the most important values concerning the quality of cross-linked polyethylene (PE-X) and the functionality of adhesives and resin-based components. Up to now, the measurement of this property has mostly

Room Temperature Phosphorescent (RTP) Thermoplastic Elastomers with Dual and Variable RTP Emission, Photo‐Patterning Memory Effect, and Dynamic Deformation RTP Response

Advanced Science, 2022
Room temperature phosphorescent (RTP) polymers have advantages of strength, toughness, and processing and application flexibility over organic small molecular crystals, but the current RTP polymers are all from rigid plastics and involve chemical linkage

Micromechanical controls on the brittle-plastic transition in rocks [PDF]

, 2022
The rheology of rocks transitions from a localized brittle behaviour to distributed plastic behaviour with increasing pressure and temperature. This brittle-plastic is empirically observed to occur when the material strength becomes lower than the confining stress, which is termed Goetze's criterion.
