Abstrakt:	The implementation of a law of mechanical behavior into the finite element software Cast3M using an open source code generator named Mfront is realized. An elastoplastic behavior model is chosen from the existing laws in the literature. Following an implicit discretization, a hardware library corresponding to the isotropic and kinematic strain-hardening model is generated using Mfront. The UMAT computer interface is used to build the library in Cast3M. The approach is vaidated by comparing the numerical results obtained with the generated hardware library and the equivalent pre-existing library in Cast3M. The simulations for the case of a tensile bar and a perforated plate show almost identical results. [ABSTRACT FROM AUTHOR]
