New Separation Method of Photoelastic Principal Stresses Using a Micro-computer

抄録

In photoelasticity, it is desirable conditions of the method for obtaining the stress distributions (a) only isochromatic lines without isoclinic lines are used and (b) the principal stresses for arbitrary shapes can be separated easily. The present paper introduces a new separation method of principal stresses satisfying the above conditions. Stress distributions in several examples are obtained by the method which use only the prescribed values of the difference of principal stresses. The results obtained are in good agreement with the corresponding results obtained by theoretical or shear-difference method.
