Amirian, B., Li, H.Y., Hogan, James D.
In this paper, a microstructure-based finite element model for nano-grained (!+↵2)-TiAl/Al2O3 cermets is proposed based on a modified variational formulation of the Gurson model for an elastic-plastic porous material. In the modeling approach, the high volume fraction of alumina, variability in...

Amirian, B., Li, H.Y., Hogan, James D.
Novel experimental data, obtained using an advanced digital image correlation technique coupled to ultra-high-speed photography, have been used to develop and validate a microstructure-dependent constitutive model for a α2(Ti3Al) + γ(TiAl)-submicron grained Al2O3 cermet. Utilizing experimental...
