Plasticity integration: satisfaction of the consistency requirement
Dear all,
I am trying to formulate the return mapping algorithm with Hill48 yield condition, isotropic hardening law and flow rule referenced to Simo & Hughes (Computational Inelasticity).
In section 2.2.2.1, equation (2.2.9) expresses the Kuhn-Tucker complementarity conditions:
In addition to conditions (2.2.9), satisfies the consistency requirement:
Shape memory effect and pseudoelasticity behavior in tetragonal zirconia polycrystals: A phase field study
Shape memory effect and pseudoelasticity behavior in tetragonal zirconia polycrystals: A phase field study, International Journal of Plasticity 60 (2014) 71–86. Martensitic tetragonal-to-monoclinic transformation in zirconia is a ‘‘double-edged sword’’, enabling transformation toughening or shape memory effects in favorable cases, but also cracks and phase degradation in undesirable scenarios.
Numerical approximation of tangent moduli
In this study, we presented a numerically robust procedure to evaluate 4th order tangent moduli which are vital for acheiving quadratic convergence of global Newton-Raphson scheme.
In this study, the proposed method is verified for hyperelastic models alone. However, the same can be extended to other constitutive models.

User Manual and Help for cadec-online
A new user manual and Help for http://cadec-online.com/ is available. It can be accessed from the Help link on the left menu tree of the app.
Additional help resources called "Abaqus Composites" and "Ansys Composites" are under construction (web and print), available At http://help.cadec-online.com/
Portuguese version of cadec-online available
The Protuguese version of http://cadec-online.com/ is available. Previous versions include English, Spanish, and Farsi. English is the base version for the developement of the app. I did the Spanish translation. Farsi and Portuguese were done by volunters. We are looking for volunteers for other translations. pls contact me if interested.
Simpleware Case Study: Fuel Cell Microstructure from FIB Data
In this case study, based on work carried out at Imperial College and University College London, research was carried out into the performance of solid oxide fuel cells (SOFCs). The microstructure of an SOFC electrode was obtained using FIB tomography, and a volume mesh generated in Simpleware software, with the model then exported to Abaqus CAE. Boundary conditions were set in the solver and stress analysis conducted, which were able to approxiamte peak maximum principal stresses in response to thermal expansion.
