Tensile Testing of Metals - Sword Flexibility

If you want a great example of Elasticity vs Plasticity-- check out this video.  In the supplemental material for "The Princess Bride", the master swordsman who helped coach the actors said that in olden days, swords were tested by putting the tip against a wall and pushing in to see how far it would bend. Then, the sword was checked to see if there was any plastic deformation.

Two-dimensional materials are flexible, transparent, compatible with living systems, and can enable new devices and physics based on their unique properties. One unique property is the ability of 2D crystals a single atom thick to undergo massive amounts of strain without failure. Since strain also drastically modifies the band structure leading to large changes in transport and optical properties, strain engineering of 2D crystals has the potential to create new devices, explore transport in pseudo-magnetic fields, and tune tunneling or excitonic effects.  ...

The objective of this exercise is to start with the simple Kronig-Penney model and understand formations of bands and gaps in the dispersion relation that describes the motion of carriers in 1D periodic potentials. The second exercise examines the behavior of the bands at the Brillouin zone boundaries. Finally, a simplified tight-binding approach for 1D lattice has to be derived as part of the third exercise..
