In this study, the stacking phase shift effect on the stress distribution was investigated for eight-harness satin weave textile composites. Simply stacked two-layer configurations with phase shifts were modeled by unit cells and repeating boundary conditions were applied at the outer surfaces. Detailed stresses were calculated by macro-element post-processing. Results were assessed to investigate the variation of stress distributions according to the manner how the adjacent tows were arranged. The changes in the failure initiation at the matrix and tows were also examined.
