where G and p are applied axial compressive stress and radial pressure respectively. Ellinas et
a1 (1984) recommended that m=n=2. A more refined interaction equation for the combined
axial compression and radial pressure may be found in Das et a1 (1992,2001). The accuracy of
the above equations, as compared to mechanical tests and other design codes is given in Das et
al(2001).
