  • A general method for implementation of elasto-plastic constitutive models into FEM programs [Elektronski vir]
    Halilovič, Miroslav ; Vrh, Marko ; Štok, Boris
    The paper deals with the implementation of elasto-plastic constitutive models, which consist from a yield condition (algebraic constraint) and evolution equations (differential equations), into the ... finite element programs. The emphasis is put on newly developed effective explicit scheme for an explicit integration of constitutive equations, which basically uses the same principles as the backward-Euler scheme, but expressions of this scheme are almost the same as in case of the forward (explicit) Euler scheme. The presented approach, despite being much simpler, reaches the same level of accuracy as the well known backward-Euler scheme, and it demands less computational operations and consumes less CPU time for one stress update operation.
