Hybrid SMA Composites
Focus: To explore the incorporation of SMAs in new hybrid composite systems and consider the effect of microstructure. The influence of matrix phases such as ceramics (MAX phases) and metals are considered. For such composites, microstructural influences are determined to aid in material design.

Micromechanical schemes are developed to determine the effective response. The effective response under loading and transformation related properties are determined. A representative composite transformation surface (Mf) is shown to the right. Different materials and compositions are studied.

Finite element analysis is also used to explore the effect of microstructure on the composite response. Numerical models are developed based off microstructure characterization (top row) and using input parameters (bottom row). Simulations are then performed to predict the local and global response. Through such analysis, the microstructure may be designed.
