• finite element method [14][15][16][17][18][19][20][21][22][23][24][25]. Using finite element simulation, Li et al. found that both loading curve and unloading curve at any depth can be generated from one indentation depth by scaling P ∝ h2 for the indentation tests of PMMA thin films with a Berkovich

• . Mechanical modeling and finite element simulation were employed to analyze the behavior of samples and optimize the manipulation method. The model used for mechanical modeling was the classical Euler–Bernoulli beam model [18]. AFM cantilever dimensions are at micrometer scale and designers are constantly
