Abstract
In the present paper, a multi-scale method from coarse grains to finite elements is developed to simulate the mechanical behavior of amorphous polymer. At the coarse grain scale, the amorphous cell method is adopted to generate the configuration of a two-dimensional random polymer. Then a main cell is considered to determine the displacement mapping relation between the nodes of finite element and the coarse grains, as well as the macroscopic material constants. Based on the mapping relationship, a new approach is proposed to deal with the handshaking region between finite element region and coarse grain region. As an example, the fracture of amorphous polymer is investigated by this concurrent multi-scale method. KEY WORDS polymer, multi-scale, finite element, coarse grain, fracture.
