There, the optical - elastic constant of the material 01 is experimentally determined by submitting the zone where the pure flexion conditions are fulfilled for a piece of optically active material to a flexion in four points with aid of the following relationship: max 1 2 0 2 K m Cd            (4) Where: K - stress in the analyzed contour; m - value of the length wave number that applies in the difference of the two polarized light components' path; 0C - optical constant of the material; d - model thickness;- wave length of the polarized light used.
Coefficient 0 od Cd     - optical-elastic constant of the material.

Semi-Solid Metal Processing - A Process Looking for a Market Plato Kapranos Department of Engineering Materials, The University of Sheffield, Sir Robert Hadfield Building, Mapping Street, Sheffield, S1 3JD, UK email: p.kapranos@sheffield.ac.uk Keywords: Semi-Solid Metal Processing, SSM, Thixoforming, Marketing, Costs, Benefits.
As already mentioned, the ability to recycle SSM material has a substantial effect on the price of feedstock.
One contributing factor to its slow development has been the urgency to push the technology to commercialisation without first establishing a clear understanding of the underlying science and in particular the fact that this urgent drive to commercialisation focused on a specific route of producing the starting material.
Fortunately the pendulum swings between the various extremes have now settled down and academia, much more competitive than in the past, once again is allowed to excel at what it does best; provide the science as well as the creativity that are the cornerstones of innovation and enterprise.

Brittle failure will happen under repeated loading even if the load level is below the static strength of the structural materials, which is named fatigue damage.
An imposed load leads to micro cracking in the structure of the cement-based material.
