| description | The effect of strain gradient on mechanical property of material is implemented through
depth-dependent stress strain relation model in conventional finite element simulations for
use in friction prediction. For the incorporation of strain gradient effect, contact simulation
involving asperities was developed with the assumption that the deformation pattern created
by asperities from tool surface in microforming is comparable to the deformation created by
the indenter in a hardness test. Consequently, depth-dependent stress-strain relation was
derived from the indentation size effect model and this stress-strain relation was used in a
simulation to show the effect of strain gradient to friction behaviour in microforming at
different surface roughness levels. Experiment was conducted alongside the simulation and
the results showed that with asperity ploughing considered as major contributor to friction in
microforming at room temperature, the simulation involving depth-dependent material
properties is able to predict the better predict the friction behaviour as compared to its
continuum simulation counterpart. |
