This view is based on the stress control fatigue properties of materials.
But when stress levels are close to the yield strength of materials, cyclic softening properties of some materials will significantly reduce the lives of mechanical elements, especially under the symmetric cycle loads.
So it is necessary to take into account of the material cyclic yield properties, which are defined as the fatigue properties of materials under the stresses close to the yield strength of materials.

The simulated materials based on finite elements method (FEM) are polypropylene alone and a fiber-based composite with a polypropylene matrix.
The control of the anysotropy of those materials, associated to a combination of low density and high rigidity enable to optimize the material parts quality.
Therefore, as those materials exhibit very low thermal diffusivity, an important thermal gradient occurs in the thickness, leading to an important gradient in the material.
Similar results and analysis are valid in case of composite materials where fibers are added to the polymer matrix.
