The direct boundary element method is used to analyze of the stress‐strain state and fracture parameters of fiber‐reinforced layered composites structures with interface bridged cracks under transient thermal and mechanical loadings. It is supposed that unbroken fibers make up bridged zone along of whole or part of a delamination region between layers of composite materials. For modeling purposes the bridged zone is considered as a part of the interface crack between of joined materials and supposed that distributed nonlinear spring‐like bonds link and constrain the crack surfaces.
