Representative cell modeling strategy of 2.5D woven composites considering the randomness of weft cross-section for mechanical properties prediction

In view of the large difference between the traditional unit-cell model (UCM) and the actual microstructure of 2.5D woven composites, which will affect the mechanical properties and failure behavior, a representative volume element (RVE) modeling strategy considering the randomness of weft cross-section (WFCS) is developed, and the established model is called statistical volume element (SVE) in this work. Based on the microscopy observation of...
