• dependent on the indenter shape, the shear modulus and H0. The ISE contributes to increased hardness in bulk solid surfaces, thin films and nano-objects. Hall–Petch effect The generation of dislocations leads to the Hall–Petch effect through the dislocation pile up mechanism or the dislocation density

• between the theoretical shear strength and the combined shear modulus, where ν is the Poisson ratio and G1,2 = E1,2/2(1 + ν1,2) [27][28]. Z is an empirical coefficient that depends on the material and ranges from 5 to 30 [29]. To calculate interfacial shear stress/strength τ for Au NPs the following

• -dependent shear modulus can vary with the ultimate force applied because of a deviation from linear viscoelastic behavior [30]. Because of their small size and the fine control over force and displacement, the point probes are particularly amenable to dynamic loading, in which a small modulation of several

• through an angle θ is given by where J and G are the torsion constant and shear modulus of the beam. In the case of a cantilever beam with a tip of length Ltip (measured from the central axis of the beam), the lateral displacement of the tip apex, Alat, is Ltipθ. Replacing the torque with the lateral tip
