A laminated beam containing an interface crack subject to thermal gradient is analyzed on the basis of the classical beam theory. The axial forces are induced in the parts of the constituent beams above and below the interface crack. For the case where crack faces are open, a nonlinear equation for determining the in-plane forces is derived by modeling the cracked part as two lapped beams hinged at both ends, and by imposing the compatibility condition of the deformations of the two beams.doi:10.2472/jsms.53.518 fatcat:r4msn3q4fbffzmpvw44ddisu5e
