The Finite Element Method (FEM) is widely used to simulate and analyze the performance of complex structures under different loading conditions. It is generally considered a reliable method for evaluating load resistance. However, the accuracy of FEM analysis is influenced by several factors, such as the accuracy of input data, the appropriate selection of analytical simulation technique, and the level of detail and accuracy of components modeled.
To ensure the reliability and accuracy of FEM results, it is important to carefully validate and verify them. This can be done by comparing the FEM results with experimental or field data, or by using other analytical methods. By doing so, engineers can identify any discrepancies and adjust the simulation model accordingly to improve its accuracy. Overall, FEM remains a powerful tool for evaluating load resistance in complex structures, provided that appropriate care is taken in the selection of input data, the simulation technique and the validation process.
