  • Detecting and evaluation of fatigue damage in concrete ...

    Therefore, the key problem of studying fatigue damage can be transformed into the analysis of damage parameter D. The value of the fatigue damage parameter reflects the accumulation of fatigue damage. For concrete with perfect non-damage status, D = 0. When damage occurs to concrete, 0 < D < 1.

  • Fatigue (material) - Wikipedia

    In materials science, fatigue is the weakening of a material caused by cyclic loading that results in progressive and localized structural damage and the growth of cracks. Once a crack has initiated, each loading cycle will grow the crack a small amount, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size which occurs when the …

    Accepted 1 February, 2011 Fatigue and rutting are very well known to be the two popular distresses that occur in road pavement. These are mainly due to the increase in the number of vehicles particularly those with high axle loads, due to the environmental conditions and also due to construction and design errors.

    fatigue damage to interfaces of aggregate/matrix, which are generally the weakest phase in concrete, as well as to soft aggregates, results in aggregate bridging stress degradation and leads to fatigue crack growth in concrete. On the other hand, fatigue life of concrete structures is controlled by fatigue crack growth behavior.
