Multiscale Modeling of the effect of sub-ply voids on the failure of composites: A progressive failure model

The effective fracture behavior of a fiber-reinforced composite depends on both the design and manufacturing of the material. During manufacturing several type of defects can occur. One of these defects are micro-voids on the sub-ply level. These can consist of either matrix voids or gaps between the fibers due to the inability of the resin to...
