Abstract
The micro- to macroscopic deformation behavior of the polymer under macroscopically uniform tension and shearing, and surface deformation of the plane strain polymer block under compression were investigated by means of computational simulation with the nonafflne molecular chain network model with slightly heterogeneous distribution of the molecular chain, in other words, the distribution of the initial strength of the polymer. The results clarified the onset of microscopic shear bands emanating from the slightly weak points and their evolution, interaction and percolation. The interaction of weak points and the evolution of surface undulation under compression have been demonstrated.Key wordsAmorphous PolymerDistribution of Initial Shear StrengthMicroscopic Shear BandMacroscopic Shear BandMolecular Chain Network TheoryComputational Simulation
