abstract
The increase in computational power has made three-dimensional analysis of textile composites practical. Interpretation of the results remains a challenge. Two non-standard techniques... calculation of stress resultants and stress volume distribution plots, were developed to transform massive amounts of output data into comprehensible modes of behavior. This study showed that in the warp tow of a plain weave, the maximum axial and transverse stress resultants occur at the maximum undulation region. An explanation of this behavior was proposed. The variation in transverse stress resultants was explained by using a simple stress transformation technique. The location of stress concentrations correlated with variation of the stress resultants. Stress volume distribution plots showed that some stress concentrations might be so localized that slight yielding might eliminate those stress concentrations. In comparable regions, the weaves studied showed similar variation in the axial and transverse stress resultants.
