The characteristics of the sheet metal process include the loss of material during the process, short processing time and excellent price and strength. The sheet metal process with the above characteristics is commonly used in the industrial field, but in order to analyze irregular field problems, a reliable and economical analysis method are needed. The finite element method is a very effective method to simulate the forming processes with a good prediction of the deformation behaviour. Among the finite element method, the static-implicit finite element method is applied effectively in order to analyze the real-size auto-body panel stamping processes, which include the forming stage.

Accurate prediction and controlling of spring-back within acceptable tolerance limits is absolutely essential for the design of bending die in order to produce sheet metal parts. This phenomenon which is defined as elastic recovery during unloading is one of the most important factors to influence the quality of sheet metal forming. This paper presents a study of spring-back in V-bending process of an isotropic CK67 steel sheet. In this investigation, in order to study the effects of significant parameters on spring-back, numerous simulations are performed using Finite Element Method (FEM). A two dimensional finite element model is developed using ABAQUS/Explicit intending to carry out a comprehensive study and prognosticate spring-back with variable parameters including punch load, punch tip radius (R p) and thickness. Numerical results obtained from the simulations are discussed in details in several diagrams. These results represent verifiable and practical data that are in line with the results of previous researchers.

With the development of the society, sheet metal filing cabinets have become popular in the office. When filing cabinets store too many paper documents, the interlayer splints often fail because of the failure of the small brackets below. The stress and deformation of brackets were studied by the theoretical method and the finite element method. Results show some small machining shape defects have little influence on the mechanical behavior of brackets. The failure reason of small brackets is not the strength, but the instability.
