Analysis of Texture Evolution and Hardening Behavior during Deep Drawing with an Improved Mixed Type FEM Element

Abstract

Abstract. In the present study, deep drawing simulations were investigated using a recently developed mixed type finite element (FE): the BWD3D. The main formulation of the element is described, with particular focus on the shear locking treatment. Two hardening models used in the presented simulations are described: the isotropic Swift's model and the physically based microstructural Teodosiu and Hu model. Finally, deep drawing results, in terms of earing profile, are compared to experiment. Special attention is paid to the effects of texture evolution and hardening models; the method used to implement Teodosiu and Hu hardening model is also discussed.

Experimental characterization and elasto-plastic modeling of the quasi-static mechanical response of TA-6V at room temperature

“…This element is a 8-node 3D brick element with a mixed formulation and one integration point. More details can be found in Duchêne et al (2005) and Duchêne et al (2008).…”

Model identification and FE simulations: Effect of different yield loci and hardening laws in sheet forming

“…Table 9 summarizes the finite element simulation data. The chosen element for this simulation is an eightnode mixed-type brick element with one integration point called BWD3D (Duchêne et al, 2005) using the new approach to prevent volume and shear locking as well as deformation without energy (hourglass modes) developed by Wang and Wagoner (2004).…”

A finite element analysis of the bending and the bendability of metallic sheets

“…[42]), has deep physical roots which makes it very efficient for various FE analyses. Further details about the hourglass and the locking treatments in the BWD3D element can be found in [43].…”
