How is Tensile Testing Conducted on Nanomaterials?
Conducting tensile tests on nanomaterials presents unique challenges due to their small size. Several methods have been developed, including:
1. Micro-electromechanical systems (MEMS)-based tensile testing: This method uses MEMS devices to apply and measure forces on nanoscale samples. 2. Atomic force microscopy (AFM): AFM can be used to apply tensile forces to nanowires and nanotubes, while simultaneously measuring the deformation. 3. In situ tensile testing in electron microscopes: This technique involves performing tensile tests inside a transmission electron microscope (TEM) or scanning electron microscope (SEM) to observe the structural changes in real-time.
