     a global limit load solution for rectangular surface cracks in plates under combined end force and cross-thickness bending is derived, which allows any combination of positive/negative end force and positive/negative cross-thickness moment. the solution is based on the net-section plastic collapse concept and, therefore, gives limit load values based on the tresca yielding criterion. solutions for both cases with and without crack face contact are derived when whole or part of the crack is located in the compressive stress zone. from the solution, particular global limit load solutions for plates with extended surface cracks and through-thickness cracks under the same loading conditions are obtained. the solution is consistent with the limit load solution for surface cracks in plates under combined tension and positive bending due to goodall & webster and lei when both the applied end force and bending moment are positive. the solution reduces to the limit load solution for plain plates under combined end force and cross-thickness bending when the crack vanishes.
