Title: Fatigue crack propagation model for plain concrete - An analogy with population growth
Authors: Ray, Sonalisa

Published in: Engineering Fracture Mechanics
Abstract: In this work, an analytical model is proposed for fatigue crack propagation in plain concrete based on population growth exponential law and in conjunction with principles of dimensional analysis and self-similarity. This model takes into account parameters such as loading history, fracture toughness, crack length, loading ratio and structural size. The predicted results are compared with experimental crack growth data for constant and variable amplitude loading and are found to capture the size effect apart from showing a good agreement. Using this model, a sensitivity analysis is carried out to study the effect of various parameters that influence fatigue failure. ¬© 2010 Elsevier Ltd.
