Treating with coils as aeolotropy, this paper brings forward a set of mathematical mode for computing internal stress distribution of coil in the process of coil coiling, in which some factors are taken into account, such as the transverse distribution of shape, crown and curl tension of the strip, the friction between the strip and the reel, the friction between strips, and etc. Because the reel shrinkage and the inner circle of the strip losing radial restrain and circumferential restrain can induce interlayer slipping and the change of the whole coil compactedness , the assumption concerned ——"virtual reel" in the process of coil uncoiling is put forward, which takes the form of slow action to express the uncoiling process and, therefore clearly simulates the variation course of internal stress distribution of coil in the process of coil uncoiling.
