Authors: Masood Nikbakht, NaghdAli Choupani, Hossein Hosseini Todeshki

In this paper the mixed-mode interlaminar fracture behavior of Carbon-Epoxy composite specimens was investigated based on numerical analyses. Study of behavior of composite materials and determining their ultimate strength seems to be an essential issue in practical engineering. Hence, the behavior of Carbon-Epoxy laminated composite is studied numerically by modeling of Arcan specimen in ABAQUS finite element software. The modeling was fulfilled in the way that loading can be carry out in different loading angles and also analyses is repeated for wide range of crack length ratio between 0.1 to 0.9. The numerical analysis was performed with ABAQUS finite element software under a constant load of 1000 N. the entire test apparatus is modeled in both 2 dimensional and 3 dimensional. Results of numerical analyses are demonstrated is several diagrams. Also, a hypothesis about boundary conditions of 2 dimensional models is investigated and has been proved. The results show that some of conventional constraints must be modified to extract right correction factors from finite element models.
