    Effect of specimen thickness on ductile fracture energy for ferrite-austenite duplex stainless steel was investigated by using tensile strain test. It was revealed that both uniform and local deformation energies decreased with the decrease in the specimen thickness. Voids in a thicker specimen can be easily formed at the lower plastic equivalent strain because of the steep increase in the triaxiality. The decrease in the local deformation energy was due to the void growth near the fracture surface depending on the steep increase in the stress triaxiality.
