The Effect on Elastic Modulus of Rigid-Matrix Tubular Composite Braid Radius and Braid Angle Change Under Tensile Loading
Download2013
Melenka, Garrett W., Leung, Cheequn K., Nobes, David S., Carey, Jason P.
The objective of this paper is to assess changes in braid radius and braid angle of braided composite tubes under tensile loading using stereomicroscope digital image correlation (DIC) based optical measurement techniques. Using this approach, displacement fields were calculated and three...

The effects of defects on the uniaxial compressive strength and failure of an advanced ceramic
Download2016
Ramesh, K., Farbaniec, Lukasz, Hogan, James D., Sano, Tomoko, Shaeffer, Matthew
This study investigates the effects of the processing-induced defect population on the dynamic compressive strength and failure of a hot-pressed boron carbide. Quantitative microscopic analysis was used to determine the distributions of three types of processing-induced inhomogeneities: aluminum...

The Effects of Intra-membrane Viscosity on Lipid Membrane Morphology: Complete Analytical Solution
Download2018-12-15
We present a linear theory of lipid membranes which accommodates the effects of intra-membrane viscosity into the model of deformations. Within the Monge parameterization, a linearized version of the shape equation describing membrane morphology is derived. Admissible boundary conditions are...

The Effects of Microstructure and Confinement on the Compressive Fragmentation of an Advanced Ceramic
Download2014
Farbaniec, Lukasz, Shaeffer, Matt, Ramesh, K.T., Hogan, James
We investigate the rate-dependent compressive failure and fragmentation of a hot-pressed boron carbide, under both uniaxial and confined biaxial compression, using quantitative fragment analysis coupled with quantitative microstructural analysis. Two distinct fragmentation regimes are observed,...

The mechanical response of a α2 (Ti3Al)+ γ (TiAl)-submicron grained Al2O3 cermet under dynamic compression: Modeling and experiment.
Download2019-01-01
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...

The study of diffuse interface propagation of dynamic failure in advanced ceramics using the phase-field approach
Download2023-02-15
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...

Schneider, Markus, Vincent, Gregory, Hogan, James D., Spray, John G.
Linear electromagnetic acceleration has a wide range of applications. Among them are applications in the field of materials science where relatively small, inexpensive systems can be of high value. For instance, it was shown recently at the French-German Institute of Saint Louis (ISL), France,...

Thermodynamically-consistent derivation and computation of twinning and fracture in brittle materials by means of phase-field approaches in the finite element method
Download2022-10-01
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...

Carey, Jason P., Melenka, Garrett W., Nobes, David S., Major, Paul W.
Archwire rotation is used in orthodontic treatment to alter the labiolingual orientation of a tooth. Measurement of the 3-dimensional (3D) motion of the orthodontic brackets requires a new configuration of the orthodontic torque simulator. The orthodontic torque simulator was coupled with a...

Nobes, David S., Major, Paul W., Melenka, Garrett W., Carey, Jason P.
Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine...
