Abstract

Fatigue life of plates damaged with multiple collinear cracks and subjected to cyclic tension loading was investigated. Results of fatigue crack growth tests with a constant tensile stress range were reported for a plate with a single crack and a plate with three collinear equidistant cracks. A simulation procedure based on numerical integration of the differential equation of a crack growth model was introduced. The Mode I stress intensity factor values, KI, were calculated by a FEM program using singular elements and assuming plane stress conditions. Using the Paris law, Klesnil- Lukás and Zheng-Hirt crack growth models, the fatigue life was simulated for the test specimens. Experiments and simulations showed a higher crack growth rate for the specimen with three cracks and 40 shorter fatigue life compared to the specimen with a single crack, which is due to the interaction of multiple cracks.
