摘要： A simulation method for analyzing a breakage of a molecular chain of a polymer material using a computer comprises: defining a polymeric material model by setting a molecular chain model in a virtual space corresponding to a portion of the polymeric material; and calculating a breaking of the molecular chain model. The calculating of the breaking comprises: a step S46 of performing a molecular mechanics calculation using the polymeric material model; a step S48 of performing a quantum mechanics calculation targeting on only a subset model including a particle model couple whose distance is greater than a predetermined first distance; and a step S54 of dissociating the bond between the particle models in the molecular chain model which particle models correspond to the particle model couple, if the distance between the particle models is larger than a second distance, wherein the second distance is larger than the first distance and equal to a distance between the particle models at an inflection point of a bond-dissociation potential plus a value of from 1.0 to 2.5 angstrom.
