In structural engineering and fracture mechanics, a crack profile (or crack opening profile) describes the geometric shape and displacement of a crack's surfaces under stress.

: Specialist designs are used to remove fatigue cracks in structures like offshore steel jackets. These designs aim to stop crack propagation.

: This phenomenon occurs when crack surfaces contact during loading, which can slow down fatigue growth. ⚕️ Crack Profili in Public Health

They prevent re-initiation by using specific notch geometries.

: In concrete, acceptable crack profiles range from 0.1 mm to 0.41 mm , depending on environmental exposure.
