• Characterization and modeling of advanced forming processes in the area of metal such as multiphase advanced high strength steel, aluminum and Niobium, using development of constitutive equations in mechanics of materials including phenomenological yield functions, crystal plasticity, molecular dynamics, and statistical mechanics.

• Structural and numerical analysis of mechanical behavior of composites* and also thermo-hydroforming process modeling of composite materials using heated and pressurized fluid.

* Polymer composites reinforced with glass, carbon, bio-fibers, clay nanotube, and graphene nano-platelets.

• Conducting experiments and numerical simulation of the forming process to show that thermo-hydroforming is a feasible process for manufacturing thermoplastic composite materials.
• Using Preferred Fiber Orientation model, which was adapted to work with a composite laminate consisting of multiple layers

• Tube hydroforming with a very precise control over the fluid pressure, and axial stroke/force, as well as uniaxial tensile test for material characterization along with Digital image correlation (DIC) system for measuring strain evolution.

• Generate 3D RVEs from Electron Backscattered Diffraction (EBSD) images to perform virtual experiments with crystal plasticity models for calculating the coefficients of advanced phenomenological yield functions to reduce the overall cost of conducting expensive experiments.
