Calculating Principal Strains using a Rectangular Strain Gage Rosette
Strain gage rosettes are used often in engineering practice to determine strain states at specific points on a structure. Figure 1 illustrates three commonly used strain gage rosette configurations. Each of these configurations is designed with a specific task in mind. The far right rosette in Figure 1 is referred to as a tee rosette. Tee rosettes are two element rosettes and should only be use...
متن کاملStrain Gage Measurements on Plastics and Composites
The bonded resistance strain gage, which is central to the topics treated here, was invented in the late 1930's and is now at about the mid-century mark in its career. During the first fifty years of its existence, the strain gage has been applied to virtually every known load-bearing material – ranging from asphalt to zirconium, and missing few, if any, of the letters in between. Whether the m...
متن کاملNoise Control in Strain Gage Measurements
Strain measurements must often be made in the presence of electric and/or magnetic fields which can superimpose electrical noise on the measurement signals. If not controlled, the noise can lead to inaccurate results and incorrect interpretation of the strain signals; and, in severe cases, can obscure the strain signals altogether. In order to control the noise level, and maximize the signal-to...

متن کاملShunt Calibration of Strain Gage Instrumentation
The need for calibration arises frequently in the use of strain gage instrumentation. Periodic calibration is required, of course, to assure the accuracy and/or linearity of the instrument itself. More often, calibration is necessary to scale the instrument sensitivity (by adjusting gage factor or gain) in order that the registered output correspond conveniently and accurately to some predeterm...
