Next, unloading-reloading cycles are repeated in constant loading rate test with Sanjome andesite and Inada granite; and unloading curves at many points along stress-strain curve are obtained.

The unloading curve normally falls below the loading curve to form a hysteresis loop.

Nanoindentation experiments were made on single crystal aluminium, and load-depth loading and unloading curves were obtained.
