A Stochastic Finite Element Analysis Framework for the Multiple Physical Modeling of Filler Modified Polymers
DownloadSpring 2021
Hamidreza Ahmadimoghaddamseighalani
Polymers have various attractive properties (e.g., low volume mass density, low cost and excellent degradation resistance), and hence, they have become essential for a wide range of applications (e.g., aerospace, oil and gas and renewable energy industries). However, due to their limited...

A Study on the Microstructure, Rate-Dependent Mechanical Responses, and Failure Mechanisms of a Novel TiAl/Ti3Al-Al2O3 Cermet
DownloadSpring 2020
Detailed characterization and experimental studies have been carried out on a novel self-propagating high-temperature synthesized (γ + α2) – TiAl/Ti3Al-Al2O3 cermet to investigate the microstructure, rate-dependent mechanical response, and rate-dependent failure mechanisms under uniaxial...

Development of Multi-Functional Add-On Hybrid Armor Models and Designs used for Vehicle Protection
DownloadFall 2022
In the first part of this thesis, a validated polyurethane adhesive model is implemented into a system-scale ceramic/armor model for ballistic impact simulations. Here, the trilinear cohesive zone (TCZM) technique is used to simulate the dynamic failure of SikaForceTM6 7752-L60 polyurethane...

ON THE ABILITY OF PROTECTIVE HEADGEAR TO ALTER SKULL AND BRAIN KINETICS DURING BLAST AND IMPACT: AN EXPERIMENTAL STUDY USING A SURROGATE MODEL OF THE HUMAN HEAD WITH NOVEL INSTRUMENTATION
DownloadSpring 2019
Blast-induced traumatic brain injury (bTBI) has become increasingly prevalent among military personnel over recent years. Head protection is fielded to mitigate the amount of energy imparted to head, as a result of ballistic and impact exposure. Despite the efficacy of contemporary headgear in...

This thesis is concerned with the experimental mechanics of brittle failure in advanced ceramics. It seeks to bridge global damage accumulation to local failure phenomena. Alumina serves as the primary model material. Other advanced ceramics (silicon carbide and boron carbide) and cermets are...
