What is a break along irregular or curved surfaces?

A break along irregular or curved surfaces is often referred to as a "fracture" or "breakage." This type of break can occur in various materials, including geological formations, glass, or ceramics, and typically results from stress exceeding the material's strength. The irregularity of the surface can influence how the break propagates, leading to unique patterns and characteristics in the fractured material. Such breaks can affect the structural integrity and aesthetic qualities of the object or formation.
