Stress–strain behavior of thermoplastic polyurethanes

Mechanics of Materials, 2005
Abstract The large strain nonlinear stress–strain behavior of thermoplastic polyurethanes (TPUs) exhibits strong hysteresis, rate dependence and softening. Thermoplastic polyurethanes are copolymers composed of hard and soft segments. The hard and soft segments phase separate to form a microstructure of hard and soft domains typically on a length ...

Stress–strain behavior of polyolefin blends

Journal of Applied Polymer Science, 1973
As part of a study on reuse of plastics as blends, the yield tensile strength, elongation at break, and the modulus of melt blends of low-density polyethylene, high-density polyethylene, and polypropylene have been studied over the entire ternary composition range. The modulus and strength are nearly monotonic functions of blend composition.

Stress/strain behavior of dental amalgams

Acta Odontologica Scandinavica, 1978
The stress/strain behavior at different strain rates and the creep rate of dental amalgams were evaluated and compared to the microstructure. The results indicate that substantial differences exist both in strength and strain at fracture. The strain at fracture for high strain rates was associated with the nature of the particle-matrix interface, in ...

Sample Disturbance and Stress-Strain Behavior

Journal of the Geotechnical Engineering Division, 1979
Different effects of sample disturbance were simulated in a resonant column apparatus that clearly show the change in stress-strain behavior when the sample is subjected to swelling, reconsolidation, shear strain, or total stress changes. A new framework that applies the concept of “reference strain” is suggested for considering disturbance effects on ...

Stress‐strain behavior of the craze

Polymer Engineering & Science, 1968
Abstract The constitution and properties of crazes in glassy polymers and their relation to crack propagation are reviewed. New evidence is discussed which shows the craze to be much softer than the parent polymer but capable of sustaining large stresses and strains up to the point of failure.

Modeling the Stress-Strain Behavior of Rubber

Rubber Chemistry and Technology, 2005
Abstract This review focuses on models for rubber that have been used to solve practical problems, either analytically or through the use of finite element analysis (FEA). The emphasis is on the mathematical structure of fully three dimensional models and the scope of behavior that they describe.

Stress/strain behavior of some dental luting cements

Acta Odontologica Scandinavica, 1978
The compressive strength, modulus of elasticity and the plastic strain at fracture have been studied for several dental luting cements. Stress/strain diagrams of cylindrical specimens using two different crosshead speeds (2 mm/min and 0.1 mm/min) at 23 degrees and 37 degrees C showed that large differences existed between various luting cements.

Sequential Enzymolysis of Ligament and Resultant Stress-Strain Behavior

Biomaterials, Medical Devices, and Artificial Organs, 1973
Enzymolysis has been used as a technique to elucidate the contributions of the two structural proteins, collagen and elastin, and the matrix ground substance (“mucopolysaccharides”) to the mechanical response of ligamentum nuchae in vitro. Specimens cut from the same ligament were drawn to failure after being subjected to varying sequences of enzyme ...

Cyclic Stress-Strain Behavior of Partially Saturated Soils

Unsaturated Soils 2006, 2006
Although soils are generally assumed fully saturated below the groundwater table, they may be semi saturated near the state of full saturation under certain conditions. The situation of partial saturation may be caused by several factors, such as variation of water table level due to natural or manmade processes.
