Load displacement curves of additive-manufactured stainless steel 316L specimens under different triaxialities

This dataset has the load-displacement data for all the fracture specimens presented in the journal article "Dey, S., Rajan, S., & Kiran, R. (2026). Developing a fracture locus for predicting ductile fracture in stainless steel 316L additively manufactured using laser powder bed fusion. Additive Manufacturing Letters, 100383." The specimens were fabricated using the laser powder bed fusion process with a laser power of 320 W, a scanning speed of 700 mm/s, a laser spot diameter of 0.2 mm, a hatch spacing of 0.12 mm, and a layer thickness of 0.05 mm. Two specimen geometries were additively manufactured: plate-shaped specimens with overall dimensions of 150 mm × 40 mm × 4 mm, and cylindrical specimens with a height of 50 mm and a gage section diameter of 5 mm. All specimens were printed directly to their final geometry, with no post-build machining performed. The geometries of all specimens were provided in the dataset. Following fabrication, all specimens were heated at a rate of 500 °C/hour to a peak temperature of 1150 °C and held at that temperature under a peak pressure of 1050 bar for 3 hours in an argon atmosphere. The specimens were then cooled inside the furnace at a cooling rate of 600 °C/hour. Mechanical testing was performed at room temperature under displacement control using a constant crosshead rate of 0.1 mm/min, ensuring quasi-static loading conditions. The gage lengths for the cylindrical and plate-shaped specimens were 14 mm and 70 mm, respectively.
