One-Step Inverse Analysis

One-step inverse analysis in Abaqus/Standard:

  • is used to obtain the initial shape of a sheet metal part given its final (deformed) configuration and a reference blank surface to which the initial configuration must conform;

  • neglects the history of the forming process by assuming proportional loading (Hencky’s deformation theory of plasticity);

  • provides an accurate method for trim line development in flanging operations by unfolding the flange onto the reference blank surface;

  • provides an estimate of plastic deformation induced during forming without detailed modeling of the forming process;

  • ignores the effects of frictional forces between the tools and the part;

  • is available only with shell elements;

  • is a static procedure that neglects inertia effects;

  • uses unsymmetric matrix storage and solution; and

  • is always geometrically nonlinear.
