Abstract
The objective of this study was to focus on the current state of finite element methods with respect to reliability in modeling of sheet metal forming processes. The trustworthiness of the FE simulations largely depends on the input material models used and correctness of the input material data. Formability parameters required for finite element analysis have been determined for Ti–6Al–4V alloy at temperature ranging from room temperature to 400 °C at intervals of 50 °C. Based on these formability parameters, various anisotropic yield criteria, namely, von-Mises, Hill 1948, Barlat 1989, Barlat 1996 and Cazacu–Barlat, have been implemented for Ti–6Al–4V alloy. In addition to that, circular deep drawing experiments have been performed in order to study the formability of Ti–6Al–4V alloy sheet at warm condition. It has been observed that formability of the material is very poor at room temperature. At temperatures above 150 °C till 400 °C, the limiting drawing ratio is found to be 1.8, which is substantially lesser than other structural alloys. Additionally, in the properly drawn cups, thickness distribution and earing tendency have been studied over the range of temperature. In order to validate the experimental results, finite element analysis has been done using commercially available software DYNAFORM version 5.6.1 with LSDYNA solver version 971. Also, failure regions during the experimentation have been identified using FE analysis. Comparison of yield criteria based on thickness distribution, earing profile, complexity in material parameter identification, and computational time has shown Cazacu–Barlat to be well suited for deep drawing of Ti–6Al–4V alloy.
