Claim 1
Independent Claim
92 words
THE METHOD OF TREATING SINUSOIDAL ELECTRICAL STRESS STRAIN SIGNALS FROM VISCOELASTIC MATERIAL BY PASSING THE STRESS SIGNAL TO A RESISTANCE CAPACITANCE PHASE SHIFT NETWORK USED TO SIMULATE THE VISCOELASTIVE PROPERTIES OF THE MATERIAL UNDER TEST TO CONVERT THE SIGNALS INTO THE REAL AND VISCOUS COMPONENTS OF DYNAMIC MODULUS WITHOUT CALIBRATION OR CALCULATION WHICH COMPRISES ADJUSTING THE PHASE SHIFT IN THE STRESS SIGNAL UNTIL THE VOLTAGE ACROSS THE CAPACITANCE IS IN PHASE WITH THE STRAIN SIGNAL, THEN RECURRENTLY MEASURING VOLTAGE ACROSS THE RESISTANCE, ACROSS THE CAPACITANCE, AND ACROSS BOTH THE RESISTANCE AND CAPACITANCE.
