scale models. These models remarkably exhibit stress magnitudes that lie between the outcomes generated by the Full Shell and Full Solid methodologies. At last, this findings strengthen the results deliberated in Figure 12 and Figure 13. Convergence tests were not conducted as the primary objective of this study is to identify FSI modelling strategies that can accurately reproduce the stress output in both the in-plane direction, similar to that of the Full Shell model, and stress in the thickness direction, as observed in the Full Solid model. Furthermore, the strategies examined in this research are anticipated to possess logical processing times, without excessive duration, and more importantly, to be computationally e ffi cient. It is worth noting that all models in this study were constructed using an identical mesh size of 3.45mm.
