Abstract:
A method of measuring strain in a material using a beam strain gauge comprising:attaching a beam strain gauge to said material, said beam strain gauge having a top leg; a bottom leg below said top leg; a beam interconnected between said top and bottom legs such that said beam is put into bending when said top and bottom legs move and at least one resistor mounted on said beam, wherein said beam strain gauge is mounted to said material by mounting said top and bottom legs to said material;applying strain to said material such that said beam is in bending;receiving an output signal of shear strain from said at least one resistor;comparing said shear strain output signal to a calibration value of said beam strain gauge, said calibration value correlating shear strain (.gamma.) output signals from said least one resistor to known strain values.
