What Does CTOD Stand For?

CTOD stands for Crack Tip Opening Displacement

CTOD, or Crack Tip Opening Displacement, is a mechanical engineering and materials science parameter used to characterize the fracture toughness of materials. It quantifies the opening displacement at the tip of a crack in a material under stress, providing critical insights into the material's resistance to crack propagation. CTOD is essential for evaluating structural integrity, predicting failure, and guiding material selection in engineering applications.
