Characteristic Points of Stress-Strain Curve at High Temperature
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
متن کاملCharacteristic Crossing Points in Specific Heat Curves of Correlated Systems
Attention is drawn to the observation that in many correlated systems (e.g. 3He, heavy fermion systems and Hubbard models) the specific heat curves, when plotted for different values of some thermodynamic variable (e.g. pressure, magnetic field, interaction), cross almost precisely at one or two characteristic temperatures. A quantitative explanation of this phenomenon, based on the temperature...

متن کاملOn the Crossing of Extremals at Focal Points
PROOF. Call the set of points KC.A a t which the Jacobian of T vanishes critical points, then I assert that if the counter image T~by b£:B, is infinite, it contains a critical point. In fact if ¥ are the coordinates of such a point b, there is a convergent sequence of points of T~b with coordinates a\ approaching a point ao from a definite direction, as is expressed by the following set of equa...
