This is expressed as the force generated per degree of slip angle (N/ °).For a given slip angle, a tyre with a higher cornering stiffness will produce a greater lateral acceleration and this is a key performance measure of any tyre.

WebIt is defined as force per unit area which is associated with stretching and denoted by σ. It is defined as the amount of tensile stress a material can withstand before breaking and is denoted by s. The formula is: σ = F/A. Where, σ is the tensile stress. F is the force acting. A is the area. The formula is: s = P/a. Web20 de out. de 2024 · Following this formulation for an axial stiffness component, AE/L = 1e4 * (1 * 1 * 20e6 / 1) ≈ 1e11 kN-m. Since other stiffness components (AG/L, aEI/L, bEI/L 2, cEI/L 3) are on the same order of magnitude, CSI s oftware uses 1e11 kN-m for rigid translational stiffness and 1e11 kN-m/rad for rigid rotational stiffness.
