PREDICTION OF FATIGUE CRACK GROWTH UNDER COMPLEX LOADING WITH THE SOFTWARE SYSTEM FRANC/FAM

摘要

For economic prosperity in the rigorous global market short product development periods are essential. Thus, the application of CAE-methods and the simulation of product performance on fast computers is enforced. This presentation deals with the simulation of fatigue crack growth under complex loading conditions. The software system FRANC/FAM, developed at the Institute of Applied Mechanics at the University of Paderborn and the Cornell University, New York, with its many options for the prediction of crack growth and lifetime analysis will be presented. FRANC/FAM enables practical-revised simulations of fatigue crack growth under complex loading. It possesses modules of practical significance for strength and fracture analyses and hence allows the prediction of damages. Crack growth in the vicinity of holes and starting from multiple cracks is shown exemplary.
