Toughness - Wikipedia

    https://en.wikipedia.org/wiki/Toughness
    In the SI system, the unit of tensile toughness can be easily calculated by using area underneath the stress–strain (σ–ε) curve, which gives tensile toughness value, as given below: U T = Area underneath the stress–strain (σ–ε) curve = σ × ε U T [=] P/A × ΔL/L = (N·m −2)·(unitless) U T [=] N·m·m −3 U T [=] J·m −3 See more

    The residual strain induced by a given stress can be determined by drawing an unloading line from the highest point reached on the se - ee curve at that stress …

Fracture Mechanics | MechaniCalc

    https://mechanicalc.com/reference/fracture-mechanics
    Failure is determined to occur once the applied stress exceeds the material's strength (either yield strength or ultimate strength, depending on the criteria for failure). In fracture …

Determination of toughness of a sample from its stress …

    https://www.researchgate.net/post/Determination_of_toughness_of_a_sample_from_its_stress_strain_tensile_curve_What_unit_should_we_assign_to_the_value_of_toughness
    Using the starting length as L and the thickness and width you can calculate stress = load/area = N/mm2. Strain = deltaL/L (no units). The area under the curve is stress x strain. That gives the...

Modulus of Toughness | How is it calculated - APSEd
