The Application of Helius in Aerospace Composite Design and Analysis

Aiming at the situation of aerospace composite application,it presents the basic theory of Multi-Continuum Technology (MCT)for mechanical analysis of heterogeneous materials.The basic idea is to construct a Representative Volume Element(RVE)for capturing the inner architecture of composite.Based on RVE,it performs the calculation the situ property of all constituents and decomposition of stress/strain.The MCT method can greatly improve the efficiency and accuracy of simulation,which is significant in the design of aerospace composite structure.
