What are the ideal properties of a 3d yield criterion. Criterio della tensione tangenziale massima o di tresca il criterio della tensione tangenziale massima fu originariamente proposto da coulomb 1773 e successivamente 1868 da tresca, a seguito delle sue indagini sperimentali sul flusso plastico di metalli sottoposti ad elevate pressioni. Il criterio tangenziale stima sempre delle tensioni piu basse o uguali al criterio della massima distorsione.
