so many Efforts have always been made to make more detailed modeling in finite elements such as Abaqus and Ansys, All finite element software such as abaqus has a home-based booklet that includes the default behavioral models for materials. If desired, a new behavioral model for these software could be defined. This requires the accurate definition of the material behavior that is presented by the researchers, and each behavioral model will have different precision and application. The studies based on modified compression field theory have been made by researchers such as Vecchio and Collins, which will increase the accuracy of the FEM models. The program is based on the FORTRAN language for the two-dimensional element based on 3D MCFT Theory by Vecchio and Collins, which are known as compression fields relations. In this paper, an attempt has been made to comprehensively examine how to introduce elasto-plastic relations in the MCFT.
