摘要: Abstract A new method to generate the random distribution of fibers in transverse cross-section fiber reinforced composites with high volume fraction is presented this paper. Based on microscopy observation cross-sections unidirectional composite laminates, hexagon arrangement set as initial status, and velocity each arbitrary at an direction, micro-scale representative element (RVE) established by simulating perfectly elastic collision. Combined proposed periodic boundary conditions which are suitable for multi-axial loading, effective properties materials can be predicted. The predicted show reasonable agreement experimental results. By comparing stress field RVE distributed randomly periodically, modulus greater than periodically.
