Influence of Bauschinger effect on springback and residual stresses in plane strain pure bending

Acta Mechanica (Impact Factor: 1.47). 08/2011; 220(1):47-59. DOI: 10.1007/s00707-011-0469-z

ABSTRACT A finite deformation elastic plastic analysis of plane strain pure bending of a wide sheet is presented. The general closed-form
solution is proposed for a kinematic hardening law assuming that the material is incompressible. The stage of unloading is
included in the analysis to investigate the influence of the Bauschinger effect, elastic properties of the material and process
parameters on the distribution of residual stresses and springback. A simple example is provided to illustrate the procedure
for finding the solution and some quantitative features of the process.

    ABSTRACT: The phenomenon of Bauschinger effect and of other generally known deformation processess of metals is explained and modeled on the mesoscale. The basic feature of the model consists in the use of tensorial internal variables that have explicit physical meaning internal mesomechanical stresses. The metallic materials under consideration are modeled as two-phase media with two substructures, one compliant and the other resistant. It is shown that Bauschinger effect and other deformation phenomena observed in most metallic materials can be explained and described as results of interplays of these substructures.

    ABSTRACT: An algorithm is proposed for springback compensation and modification for doubly curved plate, and it is established by a combination method of theoretical analysis, numerical simulation and forming experiment. Calculation equation for curvature after springback compensation is obtained based on an elastic-perfectly plastic biaxial bending model. Interpolation processing and Bezier surface blending methods are used to describe the shape of die surface after springback compensation. Based on the shape of die surface, numerical simulations and forming experiments are carried out for multi-point forming process. Simultaneously, Comparative simulations and experiments of multi-point forming process without springback modification are conducted. Simulation and experimental results show that the compensation method may effectively control the errors caused by springback in multi-point forming of doubly curved plate.
