Introduction Recently, there have been constantly increasing uses of light-weight and high-strength materials as structural materials in engineering applications such as automobile industry, 3C (Computer, Communication, Consumer Electronic) and electron industry [1,2].
Before the melting started, all the materials should be dried at 200°C for 1-2 hours.

Based on COMPASS forcefield, the relationship between microstructure and macroscopic properties of poly (propylene-co-γ-butyrolactone carbonate) (PPCG) was firstly investigated with 'Materials Studio' simulation soft successfully.
Molecular simulation is an available tool for understanding and discovering the relationship between micro-structure and functions of materials [2].
In this paper, poly(propylene-co-γ-butyrolactone carbonate) (PPCG), which has been successfully synthesized in our previous experiment, became the object of molecular simulation with the molecular simulation soft 'Materials Studio 3.0' (MS Modeling).

Above methods can change the traditional design methods rely mainly on experience to design with the safety factor approach and make using materials redundancy or lack so as to lead to materials wast and fracture or other faults because of lack of strength[3,4].
This process system is nonlinear problem that belongs to the geometrical, material and contact nonlinear analysis.
