| Abstract: |
| The Eshelby tensor calculation method of arbitrary-shaped inclusions is proposed by combining Fourier descriptor method and Green’s function method.A theoretical model for predicting the physical properties of composite materials with arbitrary-shaped particles is established based on the step-by-step inclusion method.The particle morphology in scanning electron microscope (SEM) images is mathematically characterized by Fourier descriptor method,and the geometric model with multiple meso-structural parameters is constructed.The Eshelby tensor of inclusions is solved by Green’s function.The effect of microstructure on the effective properties of the particle composite materials is studied by considering the morphology,size and component properties of the particles.On this basis,a prediction software for physical properties of the particle composite materials is designed.Taking Cu-Cr alloy as the research object,the reconstructed mesoscopic model and prediction results are analyzed,and compared with the finite element results.The validity and reliability of the calculation model are verified,and the feasibility of the application in engineering calculation is confirmed. |
