The curvature radius was derivated and the contact stress of the three-arc-sect isometric type surface was calculated through the elastic dynamics theory.
应用弹性力学理论,推导出接触点的曲率半径,对三弧段等距型面联接进行接触应力计算。

It is also unequivocally pointed out that the isometric operation cannot be precisely represented even if in a body surface modelling system which has the function of free curve modelling.
