  text: Numerical modelling of the deformation of a polymer using the finite elements
    method in axisymetrical mode was performed using the LsDyna® software to describe
    the filling of micro-cavities during the forming process of the material using
    the hot embossing. These simulations firstly allow verifying whether the chosen
    forming process conditions promote or not an optimized filling of the superficial
    cavities in order to achieve precise replicas which best reproduce the superficial
    topography of the mould. The simulations were carried out to evaluate the filling
    of the cavities taking into account the mechanical behaviour of the selected polymer
    into the model. Moreover, these models were developed to verify the effect of
    the distribution of the mould cavities on their filling. The influence of the
    mobility of non deformable rigid plates on the filling of the cavities represents
    an auxiliary variable. In the approach presented, the compression plates are assumed
    to be parallel and non deformable, whereas the polymer disk follows a rubbery
    behaviour around a temperature equal to 140°C. Globally the modelling results
    are satisfactory for they are rather close to the experimental observations conducted.
    In summary, the effect of the normal stress as also the distribution of micro-cavities
    at the mould surface seem to prevail in the case of the forming process by hot
    embossing.
