Non-linear creep of polypropylene utilizing multiple integral

نویسندگان

چکیده

<p>Multiple integral representation (MIR) has been used to represent studying the effect of temperature on amount nonlinear creep semi- crystalline polypropylene (PP) under influence axial elastic stress. To complete this research, Kernel functions were selected, for purpose performing an analogy, and arranging conditions occurrence first, second third expansion in a range between 20 °C-60 °C, i.e., glass transition softening temperatures, within framework energy law. It was observed that independent strain time increased non-linearly with increasing stress, decreased increase temperature, although parameter stress directly. In general, very satisfactory agreement theoretical practical results MIR material observed.</p>

Modified homotopy method to solve non-linear integral equations

In this article we decide to define a modified homotopy perturbation for solving non-linear integral equations. Almost, all of the papers that was presented to solve non-linear problems by the homotopy method, they used from two non-linear and linear operators. But we convert a non-linear problem to two suitable non-linear operators also we use from appropriate bases functions such as Legendre ...

Creep Prediction Using The Non-Linear Strain Energy Equivalence Theory

The Non-Linear Strain Energy Equivalence Theory, a semi-empirical model, is utilized to predict longterm creep from short-term compressive stress-strain experiments conducted at different strain rates. Stress-strain experiments in uni-axial compression are performed at strain rates of 3 and 0.03 %/minute to predict creep behavior and stress-strain data at several strain rates for an immiscible ...
