Durability Analysis of Welded Rectangular Profiles Under Damped Loads for Automotive Utilization

Fatigue performance investigation on the automotive welded structure under damped loads using the Taguchi method

“…Indeed, the results of numerical analysis cannot be validated only if the output of the finite element program converges to a single correct solution, then the element size corresponding to this converged solution is considered the best-chosen mesh size that can give stabilization of Von Mises stress output when element size is decreasing. 35 In light of the results obtained in Figure 6, we deduce that the von Mises stress converged when the element size was reduced to a suitable value corresponding to 5 mm.…”

“…Based on the mesh refinement assessed with a series of variation mesh element sizes, it is very important to check if the solution has converged to generate the finite element meshes (nodes and elements). Indeed, the results of numerical analysis cannot be validated only if the output of the finite element program converges to a single correct solution, then the element size corresponding to this converged solution is considered the best‐chosen mesh size that can give stabilization of Von Mises stress output when element size is decreasing 35 …”
