Springback is a common phenomenon in sheet metal forming, caused by the elastic redistribution of the internal stresses during unloading....

: isotropic hardening, pure (linear) kinematic hardening and combined (nonlinear kinematic) hardening. The influence of hardening models on predicting springback and final state variables such as equivalent plastic strain, sheet thickness and punch force has...

It is essential to model the Bauschinger ef-fect correctly for sheet metal forming proc-ess simulation and subsequent springback prediction when material points are sub-jected to cyclic loading conditions. For an accurate prediction of springback...

In this paper, the influences of different hardening models in simulating the L-bending process by using the finite element code, ABAQUS 6.5 have been investigated. The L-bending is modeled in ABAQUS\\\\\\\\Explicit, while the springback analysis is simulated...

In this paper the relation between characteristic (equivalent plastic) strain and springback,

taking a benchmark of NUMISHEET93 2-D draw bending and using the commercial FEM code, ABAQUS,

has been investigated. The simulations...

In this paper a FE simulation of springback in reverse cup drawing process, taken from NUMISHEET’99 benchmark is carried out, utilizing commercial code, ABAQUS. The forming process is simulated in ABAQUS/Explicit while the springback simulation...

In this paper the springback behavior of two-ply Aluminum-Steel wide laminates is investigated. An elasto-plastic analysis based on deformation theory of plasticity and the von Mises yield criterion is developed and used to investigate springback...

limited

formability and the deformation of fibers is pure elastic. Hence, the fibers cause some kind of springback

after deformation that is larger than that of the metal alloys which is known as a defect. In an

experimental method...

Springback or elastic recovery refers to the shape discrepancy between the fully loaded and unloaded configurations. Springback causes changes in shape and dimensions that can create major problems in the assembly. Hence, prediction...

Springback is the main defect in U-channel forming process. Applying the blankholder force is one of the ways of solving the prob-lem. On the other hand the value of the blankholder force should be chosen care-fully. In this paper the relation...
