A COMPARATIVE STUDY OF COMPOSITE MODELLING APPROACHES USED FOR THERMO-STAMPING PROCESS

Halil Yildirim, and Fahrettin Ozturk

Two approaches are commonly used in composite modelling; namely one shell element (OSE) model and multi-elements (ME) model. In this study, although the ME model is a more accurate approach to capture the interaction between the plies of multi-layered composites in the simulation of the thermo-stamping process, it is investigated whether acceptable results can be obtained by using the OSE model, which is a computationally efficient model for composite modeling. Simulation results show that as the relative angle of the fibers between neighboring plies increases, the results obtained with the OSE model leads to unrealistic results.
