摘要：
When a crack appears in composite materials, the fibrous system will form bridges, and the crack propagates asymmetrically as a rule. A dynamic model of an asymmetrical crack propagation is considered and investigated by applying the self-similar functions. The formulation involves the development of a Riemann-Hilbert problem. The analytical solution of an asymmetrical propagation crack of composite materials under the action of variable moving loads and unit-step moving loads is obtained.
