Mechanical stress caused by contraction of the cured coating film, due to evaporation of solvents, curing, difference in temperature or aging. This mechanical stress can induce coating defects such as delamination, cracking... . Internal stress can be reduced using plasticizers, optimizing film curing, or lowering film thickness.
Stress in a diamond or gemstone resulting from inclusions or other structural irregularities, visible through the polariscope.
Stress created within the adhesive layer by the movement of the adherends at differential rates or by contraction or expansion of the adhesive layer.
Stress produced within the metal by transformation, by temperature differences on heating or cooling, or by mechanical working.
Internal stressors are those factors, which originate from inside the body, which cause stress. Nutritional imbalance can be the result of stress, but is also a cause of internal stress. This is hidden stress, which can cause both physical and emotional problems.
stress that is generated from within the body. Causes of internal stress include nutritional imbalances, toxic metal poisoning, structural imbalances, or other internal dysfunctions.
