Crack initiation and propagation as well as abrupt occurrence of twinning are challenging fracture problems where the transient phase-field approach is proven to be useful. Early-stage twinning growth and interactions are in focus herein for a magnesium single crystal at the nanometer...

Physics-Based Modeling of Failure of Novel Light-Weight Materials: Applications to Computational Design of Materials
DownloadFall 2021
Advanced physics-based computational models have been developed in this thesis to study dynamic failure in novel light-weight materials used in impact applications, focusing on applying different computational techniques to study three material systems: 1. novel self-propagating high-temperature...

Amirian, Benhour, Abali, Bilen Emek, Hogan, James D.
Dynamic failure in advanced ceramic materials is a complex mechanical phenomenon, which is challenging to study in experimental and computational works. This work models and investigates the crack initiation, growth, propagation, and branching in two-dimensional single crystalline boron carbide...

Amirian, Benhour, Jafarzadeh, Hossein, Abali, Bilen Emek, Reali, Alessandro, Hogan, James D.
A theoretical-computational framework is proposed for predicting the failure behavior of two anisotropic brittle materials, namely, single crystal magnesium and boron carbide. Constitutive equations are derived, in both small and large deformations, by using thermodynamics in order to establish a...
