A nanoindentation study of the mechanical properties of ZnO thin films on (0 0 0 1) sapphire

Deformation and material removal in a nanoscale multi-layer thin film solar panel using nanoscratch

“…The other layers which make up the thin film region, ZnO and Al, were either too thin or too close to the edge to give consistent results. However, since ZnO has similar mechanical properties to SnO 2 [39] and Al is a soft metal, it is assumed that these layers would also deform plastically under similar conditions.…”

Effects of dynamic indentation on the mechanical response of materials

“…2,5,7,8 On the other hand, others have found that glassy polymers such as thermoset epoxy resins or poly(methyl methacrylate) (PMMA) do not exhibit this effect. Many studies have examined the effects of tip radius and geometry on the mechanical properties [12][13][14][15] but not the effect of the dynamic oscillation on the mechanical properties. 5 On the positive side, other properties such as fatigue and creep can also be studied using dynamic loading.…”
