Abstract: Proposes an analytical method for describing planar texture evolution andplastic responses in idealized crystailine polymers. The Taylor model is modified to take intoaccount the inextensibility of regtilarly foldetl molecular chains。 We introduce a continuousorientation distrihution function and represent it in the form of irreducible tensors.Theevolution equations for the tensor coefficients are derived and solved to obtain the evolvingtexture and the macroscopic respoiises of the material. The present mo...
