Comparison and characterization of a typical strain gage trace against another using the printed method

Abstract

The measuring of deformation of a strain gage is quite diverse, requiring expertise in areas like mechanical engineering, metrology, design, materials, as well as knowledge of electronic circuits, in order to use them properly. A strain gage can help determine the mechanical properties of a material, which can be obtained in two ways, the first would be by destructive tests where the rupture of the material is reached, i.e., until its destruction. The second method would be by means of nondestructive testing used to determine physical properties of the material, as well as to detect any internal failure. The focus of this paper refers only to destructive mechanical testing, among which are: bending, and traction.
