It was observed that a coarse mesh induced errors in estimation of the positive reflected peak pressure in blast scenario. used both coarse mesh and fine mesh to study the mesh size effect on numerical results of blast wave propagation and interaction with structures. Many researchers have investigated the effects of mesh size on the accuracy of numerical simulation results. The use of mesh generation techniques for dividing a complex problem into small elements plays a crucial role in FEA, which determines the accuracy of the FEA results and the requested computational time. The finite element analysis (FEA) is a powerful computational tool for performing various scientific and engineering analyses. Two types of meshes with six mesh sizes for each mesh type are considered in this study and the optimal mesh type and mesh size have been found to obtain accurate value of springback while saving as much computational time as possible. This paper presents a numerical study on revealing the mesh effects on the accuracy of springback estimation utilising ABAQUS/Standard for modelling and analyses. Meshing is a step of great importance in finite element analysis of manufacturing process as it directly determines the accuracy of the FEA results as well as the requested computational time. Accurate prediction of springback is one of the significant aspects in the finite element analysis of flexible microrolling. In flexible microrolling, springback in thickness direction is a critical indicator to determine the forming quality.
