The Multiaxial Stretching of Polypropylene at High Temperatures

Mechanics of Plastics and Plastic Composites, 1995
Abstract It has recently been shown that the crosslink-sliplink model of Ball, Doi Edwards and Warner has the property of predicting necking of the polymer network, and that it can be used to model the high-temperature drawing behaviour of polypropylene.

Effect of temperature of resistance to stretch of tortoise muscle

American Journal of Physiology-Legacy Content, 1976
The effects of temperature over the range 5-30 degrees on isometric contraction and resistance to mechanical stretches of the ramp and hold type applied to active muscle have been studied in isolated tortoise gastrocnemius muscles. The isometric tension decreases as the temperature is lowered but, when expressed as a proportion of the isometric ...

Elevated-Temperature Stretch-Flanging of Some Aluminum Alloys

Journal of Fluids Engineering, 1946
Abstract Many aircraft parts consisting of a flat web and a concave flange are produced by rubber-die-forming on a hydropress. The forming action consists of bending the flange around the die radius and stretching the outer fiber of the flange from its original length to that which is achieved when it contacts the die.

Effects of temperature and deuterium oxide on crustacean stretch receptor

Journal of Neurophysiology, 1979
1. The receptor potential was recorded intracellularly from the isolated stretch receptor neuron of crayfish. Total substitution of D2O for H2O in the bathing solution reversibly decreased the amplitude of the receptor potential to a level of 34% of the control.

Effect of Temperature on Stretched Rubber Bands

Journal of Applied Physics, 1937
Specimens of each of two vulcanized rubber compounds of known composition were subjected to various constant gravity loads in a controlled temperature chamber for several months. The lengths of the stretched bands were observed from time to time while the temperature was altered in gradual steps within a range of about thirty degrees centigrade ...

Temperature Fall and Rise of Plastics During Uniaxial Stretching

Journal of Macromolecular Science, Part B, 2011
Dumbbell specimens of common plastics—polyethylene, polypropylene, and polyamide—were uniaxially stretched and the surface temperature was measured by thermography. The surface temperature decreased at small strain below the yield point and then increased at larger strain. The endothermic deformation in the elastic regime was unexpected.

Stretching calorimetry and thermoelasticity of rubbers at different temperatures

Journal of Polymer Science: Polymer Symposia, 1984
AbstractThe data of isothermal stretching calorimetry on rubbers at different temperatures above room temperature are presented. Based upon the van der Waals equation of state for rubbers calculations can be fitted to the experimental data obtained by simple elongation whereby the thermoelastic behavior is related to a constant thermal expansion ...

Aligned solutes in stretched polyethylene: uniaxiality and temperature effects

Journal of Molecular Structure, 1997
Abstract Samples of aligned molecules may be produced by using stretched polymers as anisotropic solvents. Although the molecular alignment is rarely perfect and the orientation distribution function is not known, an exact, simple, and useful mathematical description of the partial alignment is possible.

Influence of stretching on high temperature radiothermoluminescence of polyethylene

Polymer Science U.S.S.R., 1985
The authors have investigated change in the form of the radiothermoluminescence curve above room temperature on uniaxial stretching of PE of different MM. The intensity of radiothermoluminescence exponentially rises with rise in the multiplicity of stretching at γ > 10.
