This paper developed a parametric modeling program to simulate SiCp/Al composite based on the finite element method. This modeling program developed by Python script in Abaqus

was able to achieve the visualizations of the modeling process by implementing graphical user interface (GUI). The parameters of particles like sizes

shapes

volume fractions and distribution are controllable in this user interface. In addition

a 3D representative volume element (RVE) was created for studying the microstructures of SiCp/Al composite. In order to simulate the composite’s elastic-plastic deformation process as well as its crack generation and propagation

different deformation behaviors were considered in the simulation

including the particle’s elastic-brittle failure

the matrix’s elastoplastic-damage

and the interface’s tractionseparation behaviors. To investigate the relationships between the microstructure and the mechanical properties of SiCp/Al composite

this paper built the finite element models with different particle volume fractions under different working conditions. Firstly

the impacts of particle volume fractions of 7% and 14% on the composite’s deformation and damage behavior were studied through out the tension process. Secondly

for the 7% particle volume fraction model

the compression process was simulated and compared with the tension process. Finally

the mechanism of the composite’s deformation and damage under various loads conditions was analyzed. It had been proven that this parametric modeling program was feasible to build the particle reinforced metal matrix composite model based on its microstructure

and was of great significance in studying the strengthening and toughing mechanism of composite as well as the relationships between the microstructure and mechanical properties.
