Comparative Studying of Gough, P.S Stress Formula and Kuo, K.K Stress Formula

Abstract:

Introduced Gough, PS stress formula and Kuo, KK stress formula, use the two formulas for specific examples ,the calculated results show that: the calculation results of Gough, P.S stress formula basically the same with the experimental results, stress curve was essentially fall within the range of experimental data in the curve, at the beginning of the compression phase Gough, P.S formula to calculate the stress value exceeds the value at the time of the experimental data; stress curve obtained by Kuo, K.K formula is consistent with the experimental results, when curves are basically the same at the temperature , the curve from experimental calculated very consistent in porosity in the range of , Kuo, K.K formula to calculate the results slightly in porosity in the range of ,the point which porosity is Kuo, K.K inflection point . Finally, the two formulas applicability and scope are analyzed, pointing out the limitations of the two formulas used to calculate the stress propellant.
