What Does FCG Stand For?

FCG stands for Fatigue Crack Growth

FCG, or Fatigue Crack Growth, refers to the progressive extension of a crack in a material due to repetitive loading and unloading cycles. This phenomenon is critical in the fields of materials science and structural engineering, as it influences the longevity and structural integrity of components subjected to cyclic stress. Understanding FCG mechanisms is essential for predicting failure, improving material design, and ensuring safety in various applications, including aerospace, automotive, and civil engineering structures.
