Microcosmic model built on the bas is of RSA is the key foundation of simulation analysis of Csf/Mg composites with FEM technique.As material behavior of Csf/Mg composites is dependent on the parameters including fibre volume fraction

fibre orientation distributions and fiber length-diameter ratio

the efficiency would be reduced obviously if FEM models were established manually according to different simulation requirements.Therefore

a Python scripting language was used to establish a user defined graphic interface through second-developed ABAQSU GUI.The results indicate that it is viable to generate a graphic user interface with second-developed ABAQSU GUI according to clients’ demand

and the geometric model of Csf/Mg composites can be built automatically by inputting related parameters.Meanwhile

the modeling process is greatly simplified.The two-dimension or three-dimension geometric modeling of short fiber reinforced composites in which the orientation distribution of fibers exhibits random or uniform can be realized by using the RSA schemes.
