What Does CMOD Stand For?

CMOD stands for Crack Mouth Opening Displacement

CMOD, or Crack Mouth Opening Displacement, is a critical parameter in fracture mechanics that quantifies the relative displacement of the crack surfaces at the mouth of a crack under external loading. It is often used in the analysis of material performance and integrity, particularly in assessing the behavior of structural components subjected to stress and fatigue. CMOD measurements are essential for predicting failure mechanisms and enhancing the design of materials and structures in engineering applications.
