ABOUT ASHKAN ALMASI

I am a Senior Engineer in Hot Section Engineering at Pratt & Whitney. Previously, I served as a Postdoctoral Research Associate in the Department of Mechanical Engineering at the University of Connecticut, focused on developing a 3-D multi-scale framework combining the mixture theory with the multiscale FE-method (i.e. finite elements of multiscale mixtures, FE2M) to solve two-scale, non-linear, coupled and time dependent boundary value problems (BVPs) for fluid-saturated porous media.I completed my PhD in Computational Multiscale and Multiphysics (CM2) Lab in the Department of Structural Mechanics at the University of Colorado Boulder. My research focused on developing numerical methods for important class of engineering applications such as microstructure evolution, contact mechanics, and frictional crack growth. My Ph.D. thesis involves predicting polycrystalline solidification with a diffusive interface approach and stress analysis with the material interfaces, i.e. grain boundaries. My dissertation also proposes a strong form meshfree collocation method for frictional contact problems. Also, I developed computational methods for modeling friction in crack surfaces based on the strong form meshfree collocation method. During my master studies, I coupled Finite Elements with stochastic analysis to predict the Young\'s modulus of the nanocomposite. I also used the computational homogenization and hierarchical multiscale modeling to study the behavior of the interphase layer and its effect on the overall stiffness of polymer (epoxy) clay nanocomposites.
