Fall 2017
Approaches for accurate prediction of ductile failure of polyethylene (PE) pipe have been explored using the experimentally determined, material-specific damage parameter D. Although many methods are available for quantifying the D values, they are mainly suitable for metallic materials. For...

Deformation Transitions and their Effects on the Long-term Performance of Polyethylene and its Pressure Pipe
DownloadFall 2021
Ductile-to-brittle (DB) transition is of tremendous importance for lifetime prediction of polyethylene (PE). Majority of current methods for determining critical stress for the DB transition of PE products use notched coupon specimens in order to shorten the test timeframe. However, those work...

Investigation of the Molecular Mechanism of the Environmental Stress Cracking of Polyethylene by Molecular Simulation
DownloadFall 2024
In this molecular dynamics (MD) simulation study, we investigated the impact of an environmental stress cracking (ESC) agent, nonyl ethoxylate (NE), on the packing and free volume coalescence in between polyethylene chains and the ESC agent, focusing on linear polyethylene (LPE) and branched...

Mapping the Microstructure of Single-Site Ethylene/1- Hexene Copolymers Using Response Surface Methods
DownloadSpring 2022
Polyolefins are a commercially important class of polymers made only of carbon and hydrogen atoms. Polyethylene accounts for a sizable fraction of commercial polyolefins, covering applications from packaging films, water tanks, biomedical equipment, bulletproof vests, and adhesives. The use of a...

Polyethylene-based Microfluidic System Approaches to Achieve Adaptive Visible and Thermal Camouflage Applications
DownloadSpring 2024
Camouflage represents a critical skill in both nature and combat zones, as it enables concealment from potential threats. With the advancement of visual and infrared-sensitive surveillance equipment, adaptive camouflage across the visible and infrared (IR) spectrums has become increasingly...

Polymerization Kinetics and Structure-Property Relationships of Ethylene/1-Hexene Copolymers
DownloadFall 2018
Caldera Palacios, Anuar Alfonso
Polyethylene accounts for 32% of the world’s plastics production and it is continuing to grow for the foreseeable future. Its versatility to modify its molecular structure using different types of catalyst or modifying the reaction conditions makes polyethylene suitable for a wide range of...

Fall 2011
A new mechanistic approach is applied to characterizing toughness of low-density polyethylene (LDPE) in ductile fracture, introduced in double-edge-notched tensile (DENT) test. Three mechanisms were involved in the new approach, i.e. fracture surface formation, necking and shear plastic...

Water Absorption and Performance Degradation of Natural Fiber Reinforced Thermoplastic Composites
DownloadFall 2017
Natural fiber reinforced polyethylene biocomposites are an environmentally friendly alternative to non-biodegradable thermoplastic materials. The addition of natural fibers to polyethylene improves mechanical properties such as tensile modulus and tensile strength. Unlike thermoplastics,...
