Tensile Stress Relaxation Behavior of Polyethylenes

Effect of Fabric Structure on the Tensile Stress Relaxation of Net Warp Knitted Fabrics

Comparison of Compressive Stress-Relaxation Behavior

Osteoarthritis (OA) is a common joint disorder found mostly in elderly people. The role 21 of mechanical behavior in the progression of OA is complex and remains unclear. The 22 stress-relaxation behavior of human articular cartilage in clinically defined osteoarthritic stages 23 may have importance in diagnosis and prognosis of OA. In this study we investigated differences 24 in the biomechani...

Creep and Stress Relaxation Behavior of Polypropylene, Metallocene-Prepared Polyethylene and their Blends

Effects of Temperature and Loading Characteristics on Mechanical and Stress-Relaxation Behavior of Sea Buckthorn Berries. Part 3. Relaxation Behavior

Relaxation force properties of single sea buckthorn berries under uni-axial compression were studied. Sea buckthorn berries had a time dependent behavior similar to other viscoelastic materials. The three-term Maxwell model with a maximum relative difference (MRD) of % 5 ≤ was chosen as the best fit equation to the relaxation data. For both Indian Summer and Sinensis cultivars, the firmness (as...

Catalytic Hydroxylation of Polyethylenes

Polyolefins account for 60% of global plastic consumption, but many potential applications of polyolefins require that their properties, such as compatibility with polar polymers, adhesion, gas permeability, and surface wetting, be improved. A strategy to overcome these deficiencies would involve the introduction of polar functionalities onto the polymer chain. Here, we describe the Ni-catalyze...
