Nano-Mechanical Testing

Nano-mechanical Test: Computational analysis of cardiovascular mechanics requires the ability to capture the complex in-vivo mechanical response of biological materials. The mechanical response of biological materials are greatly heterogeneous and depended on several biological (age, gender, race) and bio-mechanical (hemodynamic load, presence of device) factors. Nano-mechanical test such as the nano-indentation is an important tool for rapid and precise non-destructive localized mechanical property evaluation and mapping. My continued research in cardiovascular mechanics will focus on developing and using nano-indentation techniques for investigating soft-tissue biomechanics.

I have extensive experience in indentation and scratch test (MicroMaterials Nanotest 600) as a tool to study localized deformation and wear-resistance response of engineering materials.
