Beschreibung
Zusammenfassung:	A device (1) for simulating a viscoelastic property of a polymer composite material in which a filler is dispersed in a matrix polymer includes: a storage unit (3) that stores a simulation model (M) formed by a model of a matrix phase (B) of the matrix polymer, a model of the filler (A), and a model of an interface phase (C) of the matrix polymer; and an analysis unit (4) that analyzes a storage elastic modulus and a loss elastic modulus of the polymer composite material by solving a dynamic equilibrium equation in a case where a vibration strain (U(t)) is applied to the simulation model (M). The model of the interface phase C is a model in which a storage elastic modulus and a loss elastic modulus in the interface phase C are defined using a phase field variable (x) for setting a ratio between a rubbery state and a glassy state of the matrix polymer.
