[TS I-5A.4] Modeling flow and work hardening behaviour

In the present investigation, the tensile ow and work-hardening behaviour of a cold worked Zr-2.5Nb pressure tube material of IPHWRs has been studied over the temperature range of 30 °C to 600 °C. The stress strain data have been analysed in terms of stress-strain relations proposed by Hollomon [2], Voce [3] and Ramberg-Osgood (RO) [4].Work HardeningWork Hardening. Work Hardening. Dislocations interact with each other and assume configurations that restrict the movement of other dislocations. As the dislocation density increases there is an increase in the flow stress of the material. The dislocations can be either strongor weakobstacles to the movement of other dislocations, depending upon the types of interactions that occurs between moving What is the relationship between stress and N? As n varies, the shape of the true stress-strain curve also alters (see figure). If n is low, the work- hardening rate is initially high but the rate decreases rapidly with strain. On the other hand, with a high n, the initial work hardening is less rapid but continues to high strains. Kn.See all results for this question

What is the expression for strain hardening?

The most commonly used expression for strain hardening is the simple power law. As n varies, the shape of the true stress-strain curve also alters (see figure). If n is low, the work- hardening rate is initially high but the rate decreases rapidly with strain.See all results for this questionWhat is stress strain behavior?Stress-Strain Behavior of Polymers. It means, when a plastic specimen is pulled at a (constant) strain rate the applied stress (or load) is directly proportional to the observed strain (or elongation). The maximum stress up to which the stress and strain remain proportional is called the proportional limit.See all results for this questionWhat is a stress strain curve?Strain is the percent change in the length of the material. The stress-strain curve is the simplest way to describe the mechanical properties of the material. The stress-strain curve can provide information about a materials strength, toughness, stiffness, ductility, and more.

But remember: as we pull the material, the cross-sectional area decreases. Since this is an engineering stress-strain curve and we assume the cross-sectional area stays the same, the stress appears to decrease.
