Experimental and Numerical Analysis with MSC Marc Software for the Characterization of Two-component Moulded Parts

obtained through this analysis.The use of the G’Sell-Jonas model offers a good prediction regarding the mechanical behaviour of the two component tensile test specimens on both the elastic and the plastic regions. The simulation of the mono-component tensile test showed a good agreement between the experimental and the predicted results, with a correlation coefficient ranging between 0.9973 and 0.9998. High levels of confidence were obtained for the mono-component tensile test specimen results, further applied for FEA analysis of the two-component specimen (HDPE/LDPE). The necking effect observed in the experiments, at a 255°C melt temperature for the LDPE, was similar to the one revealed by the finite element analysis.
