Stress-erosion cracking of herringbone mesh belts is a general term referring to the mutual failure of stress-bearing alloys in aggressive environments due to the propagation of cracks. Stress corrosion cracking exhibits a brittle fracture morphology, but a herringbone pattern can also occur in materials with high toughness. The necessary prerequisite for stress-corrosion cracking of herringbone mesh belts is the presence of tensile stress (whether it is residual stress or applied stress, or both) along with a specific corrosive environment. The formation and expansion of the herringbone mesh belt are roughly perpendicular to the direction of tensile stress. The stress value that causes stress corrosion cracking in the herringbone conveyor belt is much lower than the stress required for the material to fracture in the absence of an erosive medium. At the microscale, cracks that pass through the grains are called transgranular cracks, while those that propagate along the grain boundaries are known as intergranular cracks. When the stress-induced cracking progresses to a certain depth in the herringbone patterned material (that is, when the stress on the cross-section of the material under load reaches its fracture stress in air), the material breaks in the manner typical of normal cracks (in ductile materials, this usually occurs through the aggregation of microscopic defects). The cross-section of a part that fails due to stress corrosion cracking in a herringbone mesh belt will contain characteristic areas of stress corrosion cracking as well as \"ductile pit\" areas associated with the aggregation of existing microdefects.
