Effects of fiber orientation of adjacent plies on the mode I crack propagation in a carbon-epoxy laminates

The influence of ply orientation on the resistance to mode I delamination of multidirectional composite laminates can be assessed by Double Cantilever Beam (DCB) tests. However, one of the difficulties associated with such a study is the change in overall elastic parameters occurring when modifyin...
