Web7 mrt. 2024 · The torsional stiffness is calculated according to the following formula: K m =ML/θ Where M — applied torque (n · m); L — distance from the torque action position to the fixed end (m); θ—— Torsion angle (°) 3. Relationship between strength and stiffness WebFracture strength is the value corresponding to the stress at which total failure occurs. Stiffness is how a component resists elastic deformation when a load is applied. Hardness is resistance to localized surface deformation. Normal Strain: deformations that occur perpendicular to the cross-section; normal strain is caused by normal stress.
