Finite element simulation. (a) The top sequence shows the result of the simulation of the progressive indentation by a cylindrical probe in the sensor cell. Arrows show direction and magnitude of principal strain. Beyond 0.4 mm of deflection, the behaviour departed from a Hertzian model as indicated by the pressure profile. The bottom sequence shows the unloading phase after a five-second plateau at fixed indentation. (b) Axial and transverse strain profiles along the MWCNT film during the loading phase.
