method for visual monitoring of the deformation of a deformable body in uni - and / or multi - direzionalmente.

摘要

on the surface of the body, prior to its deformation, gives a series of geometric figures.these figures are such that change shape due to the deformation of the body on which they are reported.the geometric figure having a favorite ellipse with its major axis directed in the direction of the deformation of the body.the geometric figure is stated on the body by stamping with paint and / or inks of normal type, if necessary, heat resistance, or other suitable means, such as superficial incision.the geometric figure is small compared to the degree of desired deformation of the body.
