Ursache von "Dehnung"

Basics on the technical term of "strain"

Strain is caused, for example, by the action of force on a material. However, it can also be caused by temperature, or by various physical effects.
When stretching in response to a force, one speaks of "deformation".
If the strain is caused by a change in the temperature, this is called thermal expansion.
By the magnetostrictive effect and by the piezoelectric effect, strains are caused by a magnetic or electric field.
