摘要：

The formation of slanted fracture under plane strain conditions is studied using the finite Element (FE) method. Constitutive models proposed by Rousselier and by Gurson are used. Rice's condition for localization is checked at every point of the FE mesh for each time step. The role of mesh design (element size, element aspect ratio, symmetry) is first studied. The different constitutive models are then compared. It is in particular shown that the use of the f. function in the Gurson model favors flat fracture. (C) 2002 Elsevier Science Ltd.
