Hi,
Assume that we have a composite structure consists of isotropic layers with
a delamination (separation) between the layers. There is a compressive load
applying normal to layers surfaces and hence normal to the
delamination (crack) which closes the delamination, and a shear load tangential to the
crack surface.
the order of shear force is much smaller than the compressive load. can the
delamination propagate du to this shear force?
