208 非晶性ポリマー内部の分子鎖折りたたみ構造に関する分子動力学解析  [in Japanese] Molecular Dyamics Study on Folded Chain Structure in Amorphous Polymer  [in Japanese]

Glassy polymers show complex deformation behavior due to the internal inhomogeneous structure composed of the random-coil chains and the locally crystallized chains. In the present study, several molecular dynamics simulations are conducted on an amorphous polyehylene containing eight folded chain crystals. It is suggested from the simulations that the composite does not show anisotropy in the stress-strain behavior while the internal chain structure differently deforms.
