4. Results and Discussion In structural analysis, it is important to consider the appropriate mesh element size for accurate results. One of the key factors that can be determined by analyzing the mesh size is the von Mises stress, which is a measure of the stress that a material can withstand. The element numbers and the results of static analysis are usually recorded in a table, such as Table 3, for easy comparison. It is important to note that the mesh element size can have a significant impact on the maximum von Mises stress results. As presented in this study, decreasing the mesh element size can lead to an increase in von Mises stress. Therefore, it is crucial to carefully consider the appropriate mesh element size for each analysis to obtain accurate and reliable results.
