| Abstract: | 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.
