Successfully completed the numerical implementation of mechanism based strain gradient crystal plasticity in Abaqus/Standard (UMAT subroutines) to capture scale dependent plasticity of the fully lamellar structures TiAl alloy, in which the lamellar thickness varies from colony to colony. The model takes into account proper continuum descriptions of geometrically necessary dislocations and statistically stored dislocations, allowing a better description of hardening for different phases. This model was validated for the PST-lamellar crystal with different orientations by comparing the simulation results with available experimental data. This model was used in a multiscale framework to capture the microstructure dependent mechanical behavior of a TiAl polycrystal.
Results were presented at International Conference on Gamma Alloy Technology, Tolouse France (2013)
Project - 2 \[01.2013 - 06.2013\]
To setup a framework for multiscale computations with Abaqus/Standard through UMAT and related user utility subroutines. The material properties at the integration points are evaluated through multi-level Abaqus UMAT computational setup for composites and materials with heterogeneous microstructure.
