caustics

strong alkaline chemicals, such as hydrofluoric acid, that destroy soft body tissues, resulting in deep penetrating burns and corrosion of the skin, eyes, and mucous membranes on contact. Caustics are usually the hydroxides of light metals. Exposure may be by inhalation or ingestion. Treatment of exposure to these agents involves irrigation of exposed areas and neutralization of the substance.

As the loading progresses further, these deformation zones grow further; in our implementation of the method of caustics to the evaluation of the J integral, measurements were performed only when the LDZs were small compared to the extent of the fatigue precrack and furthermore, the measurements were performed well outside the LDZs.
The method of caustics or shadow spots has found widespread use in experimental fracture mechanics, notably in dynamic situations, perhaps because of the ease with which data may be gathered, interpreted and analyzed.
