 note = {The modified Cam-Clay model (MCCM) has been widely uesed in the description of elasto-plastic behavior of clays. MCCM has a yield function which is an ellipse in p-q stress system. An adoption of the yeild function is very important because of the form of it effects the stress strain curves of clays.\nIn this paper, the equation of the ellipse used in MCCM has been extended, and then using this equation, a new elasto-plastic constitutive equation for clay was introduced., 紀要論文},
