Elasto-plasticity Homogenization Analysis of CFRP
Performing the homogenization analysis for one-way reinforced material with carbon fiber and polyimide resin.
Evaluating the macro characteristics of the stress - strain by performing a pure shear numerical material test to the material model in one direction respectively to the single axes of the three directions. Identifying the material constant of anisotropic elastic-plastic constitutive law (anisotropy of HILL) which is used in ANSYS based on these test data.
Finally, performing numerical material test on the homogenized model in order to verify the validity of the equivalent property values obtained in this analysis, and comparing the results of both. It does not provide a perfect match over the whole strain range, but it is not a significant difference at a practical level.
