In this paper the plane strain problem for two bonded orthotropic laye
rs containing a crack perpendicular to the laminate surfaces is consid
ered. After deriving the integral equation for the general problem, th
e solution is obtained for three main crack geometries, namely an embe
dded crack, a surface crack and a crack terminating at the interface u
nder a remotely applied membrane load or bending moment. For the crack
terminating at the interface the necessary asymptotic analysis is car
ried out, the characteristic equation to determine the power of stress
singularity beta is obtained, and the influence of the material param
eters on beta is examined. The main results given in the paper consist
of the stress intensity factors obtained for various crack geometries
, material combinations and loading conditions.
