Stresses in Composite curved Beam

Stresses in Composite curved Beam

(OP)
I'm looking for formula  to determine the Interliminar and shear stress in a composite curved beam.  Can anyone help me?  Thanks.

RE: Stresses in Composite curved Beam

The interlaminar normal stress in a curved quasi-isotropic laminate can be approximated by -1.5*M/Rm*t where M is the moment per unit length, Rm is the mean radius, and t is the laminate thickness. I think you can find this in the Niu composit book.
