With the development of science and technology, multiphase composite materials with many attractive behaviors, are used more and more widely in many important industry fields, such as aerospace, automobile, military production, nuclear energy, electronic industry and so on. Studies on the multiscale for multiphase composites are a kind of challenging important multidisciplinary problem. Because the phenomenon of multiscale reflects the basic nature of matter world as well as multiphase composites, it has great wealth scientific connotation. The fundamental research on the integrated design of key material has attracted worldwide attention. As the core of industrial innovation design and digital design, CAE technology plays an important role in the research of materials design. CAE technology is the key technology to improve the competitiveness of enterprises and ensure national security. It plays an important role in the manufacturing industry and the national economy..1. In this project, the Deep Convolution Generative Adversarial Networks (DCGAN) model of artificial intelligence will be made for the characterization of multiphase composite materials..2. In this project, a new kind of simulation method of real multiphase composite materials will be studied, and a series of new assumed stress hybrid finite elements will be established, which are expected to make pioneering achievements in the field of damage simulation of real multiphase composite materials and expand the scientific frontier..3. This project focuses on the national economic strategic demand of independent CAE software, establishes an open CAE system for macro and micro analysis of multiphase composite materials, realizes the macro structure analysis, micro damage evolution analysis and multiscale analysis of real multiphase composite materials with millions of randomly distributed reinforced phase microstructures.
