The local microstructure distribution
strongly affects the mechanical behaviour of semi-crystalline parts, as with
all other inner properties. To create an integrative simulation process of the
microstructure dependent part properties, it is essential to simulate the whole
process step first and to take the local spherulite
distribution into account. The crystallisation itself is dominated by the
chosen process parameter. Based on this aim an online calculating software tool
has been developed to compute the local spherulite
growth and its distribution in moulded cross-section. The realisation, first
simulation results and initial optimisations are presented in this paper.
