Notes:
Procedures for smoothing experimentally determined displacement fields are presented such that dynamic, non-steady-state metalworking processes can be analysed using the visioplasticity method. The procedure establishes a rectangular grid in which strain, strain rate and stress values may optionally be obtained at all points on the grid. The condition of material continuity is automatically satisfied by constraints during polynomial smoothing in position and time, using the Gram-Schmidt orthogonalization technique. Examples are given of quasi-static and dynamic plane strain upsetting operations.
