Modification of the Bonora Damage Model for shear failure

Nicola Bonora, Gabriel Testa, Andrew Ruggiero, Gianluca Iannitti, Domenico Gentile

The Bonora damage model was extended to account for shear-controlled damage. To this purpose, a new definition for the damage dissipation potential in which an explicit dependence on the third invariant of deviatoric stress was proposed.…
