Today, Composite materials with their prominent characteristics like high specific stiffness and strength have extended application in different industries. Beside these advantages, some disadvanteges like brittle fracture and low failure strain leads to enhance their properties by putting them together with other materials and joining them together in some applications. By putting carbon fiber reinforced composite beside steel, the problem of the low fracture strain of composite would be solved while the specific stiffness and strength would increase. On the other hand, the complicated behavior of composite materials as unisotropic and laminar material cause complexities and uncertainities in analytical methods using for evaluating the strength. Therefore, by development of numerical modelling and computational tools, finite element modelling in meso and micro scale is used as an effective way to investigate the strength of composites. In this research, finite element modelling of steel-continious carbon fiber composite hybrid in mesoscale will be done to investigate the ultimate strength and strain in simple uniaxial test. So, the model will be produced by using python scripting in ABAQUS software. The model has specifications like random distriburion of fibers to reach the specified volume fraction, periodic boundary condition, appropriate meshing in order to applying periodic boundary condition and other required steps to be implemented in ABAQUS. In addition, suitable constitutive equation for carbon fiber in elastic-fracture mode will be defined using ABAQUS subroutine UMAT. In the constitutive equations, the strain based fracture criterion is used and fracture evolution is evaluated based on brittle fracture. Also, carbon fiber strength distribution according to the Weibull probability distribution is considered in the modelling. According to the results, the model can predict the stiffness, fracture strength and strain of CFRP and also stiffness of steel-CFRP hybrid in fiber direction. The fracture strain of carbon fiber composite, contributing in steel-CFRP hybrid, shows meaningful increase in comparison with virgin CFRP. Current simulations could not predict this phenomenon, however, to find out the reason of this phenomenon, the effect of applied transverse strain from steel on resin, fiber and interphase behavior, the effect of production method and the effect of load carrying by fractured fibers are investigated. It can be concluded that the production method of steel-CFRP hybrid has considerable effect on the behavior of hybrid in fiber direction by applying uniaxial tension loading.
