Criterio di Tresca - Wikipedia

WebCriterio di Tresca. Rappresentazione dei due criteri nel piano delle tensioni principali: l'esagono di Tresca (in blu), che corrisponde al criterio tangenziale, è più cautelativo dell'ellisse di von Mises (indicato in rosso) che corrisponde al criterio distorsionale. Il criterio del massimo sforzo tangenziale è un criterio di resistenza ... WebThe 0.58 factor can be derived from the Von-Mises criterion. Von-Mises criterion is a failure theory that is based on the 3D stress state, and yields a scalar value for stress—the “von Mises stress”. Per the theory, failure occurs when the VM stress exceeds the tensile strength of the material. ... VM stress = sqrt ( 1/2 * (6* tau^2 ... WebLudwig von Mises (1881-1973) The Austrian economist Ludwig von Mises (1881-1973) wrote widely on matters such as highly technical works on monetary theory as well as journalistic pieces designed for a broader audience.

If you add a compressive stress from the sides, then the von Mises will be greater than the max principal, which stays the same. Look at the formula for von Mises.

WebAs shown in [2], for one-dimensional real-valued variables, the energy distance is linked to the non-distribution-free version of the Cramér-von Mises distance: D ( u, v) = 2 l 2 ( u, v) = ( 2 ∫ − ∞ + ∞ ( U − V) 2) 1 / 2. Note that the common Cramér-von Mises criterion uses the distribution-free version of the distance.
