    On Adaptive Calculation of Kirchhoff Plates with Mixed Method

    An adaptive refinement and enlargement procedure for calculation of Kirchhoff plate bending is presented. Mixed triangular elements with linear displacements and constant moments are used. The error indicator ...

    Numerical Integration of Finite Deformation Elastoplasticity with Application to Sheet-Forming

    Finite element algorithms for large elastic-plastic deformation are predominantly based on explicit integration of the constitutive relations on tangent stiffness form. The final stress must be corrected back ...
