stress function

stress function

[′stres ‚fəŋk·shən]
(mechanics)
A single function, such as the Airy stress function, or one of two or more functions, such as Maxwell's or Morera's stress functions, that uniquely define the stresses in an elastic body as a function of position.

[1,2,5], we introduced the Hierarchical Multi-mode Molecular Stress Function (HMMSF) model for LCB polymers, which implements the basic ideas of the pom-pom model, hierarchal relaxation, dynamic dilution, and interchain tube pressure.
The heat stress function used meteorological data collected from public weather stations, rather than directly from farms; however, genetic evaluation should not be affected by this substitution, because the use of HYS compensates for farm effects.
An alternative approach to solve the Saint-Venant torsional problem is to introduce a stress function, [phi].
(2) Generally, the complex stress function obtained through two cycles of iteration can satisfy the engineering demand [19].
Over time, these patterns of stress function should result in longer telomere length."
Diaco analyses orthotropic Saint-Venant beams under torsion, for which a skillful solution method has been recently proposed by Ecsedi considering a class of inhomogeneous beams with shear moduli defined in terms of Prandtl's stress function of corresponding homogeneous beams.
Basic Equations for Solving Complex Stress Function
where u(x, y) is the stress function, G is the shear modulus, while v is the angle of twist per unit length of a bar.
