Unformatted text preview: re known. Remaining is to check the reductions in burst and collapse resistances caused by biaxial loading. Fig.33 shows tension loading versus depth after cementing, is used to evaluated the effect of biaxial loading. 186 Copyright(c) 2005 by Ali Ghalambor & Boyun Guo 93 Fig.33 Biaxial Design 187 Point Loading Calculation ⎡ ⎤ 6 KJ Fb = 218 Dp φ As ⎢ Tanh ( 6 KJ ) ⎥ ⎣ ⎦ Where: Fb = Bending Force(Additional Tension Load) (lbs.)
