چکیده
|
In this work a double step algorithm is presented for the integration of equations governingthe behavior of von mises material in plastic limit. the isotropic and kinematic hardenings employed areof general type and the evolution of back stress follows the armstrongfrederick rule. theoretical andnumerical aspects are discussed in detail and a comparison is made with the classical backward eulermethod.
