In materials science, fracture toughness is the critical stress intensity factor of a sharp crack where propagation of the crack suddenly becomes rapid and unlimited. A component's thickness affects the constraint conditions at the tip of a crack with thin components having plane stress conditions and thick components having plane strain conditions. Plane strain conditions give the low… WebMar 1, 2024 · In the present experimental work, the behavior of AISI H11 and AISI H13 tool steels will be studied by tensile and strain controlled low cycle fatigue tests at different temperatures: 20 °C, 200 °C, 350 °C and 550 °C. The cyclic tests will be performed in tension and in compression at four strain levels, i.e. 0.4%, 0.6%, 0.8% and 1% [10], [11].
