Abstract Fuzzy uncertainty texture spectrum (FUTS) is applied for the pattern
recognition of fracture surface morphologies. Linear minor distance
classifier is used to classify five typical fracture surface
morphologies, including equiaxed dimple, elongated dimple, cleavage
failure, fatigue and intergranular cracking. With testing results,
the method of FUTS is highly efficient in fracture morphologies
classification.
