The inverse approach with simple triangular shell elements for large strain predictions of sheet metal forming parts. (English) Zbl 0954.74057
The authors present a triangular shell element with constant membrane and bending strains to estimate large elasto-plastic strains encountered in thin sheet metal forming. The internal force vector and logarithmic strains through the thickness are derived, and some applications illustrate the validity of this numerical procedure.
