Macro and micro mechanical properties of TiC particle reinforced titanium matrix composites

Finite element (FE) framework for solving the periodic multi-scale problems is presented by using homogenization theory and fixed point iteration method. FE unit cell models of TiC particle reinforced titanium matrix composites with typical micro-structure were established. Displacement boundary conditions for FE cell models were obtained from macro-scale by adopting the fixed point iteration method. Numerical simulations were performed to study the tensile behaviors of the TiC particle reinforced titanium matrix composites and the macro-effective mechanical properties were given. A good agreement is achieved between the experimental results and the numerical predictions, revealing the reliability and effectiveness of the presented techniques.
