Shear and normal stresses in uniaxial compaction.
… of materials were chosen to investigate the uniaxial compaction of particulate solids. Dentritic and cubic sodium chloride were chosen as plastically deforming, dicalcium phosphcte and sugar as fragmentary and styrocell, homopolymer and copolyrinier as non-compactable materials. The uniaxial …

Cyclic Uniaxial Constitutive Model For Steel Reinforcement
… of appropriate constitutive models. Several uniaxial material models have been developed for reinforcing steel. Existing material models sacrifice efficiency for accuracy or vice versa. Conceptually simple and numerically efficient models do not accurately capture the hysteretic response and …

Quantitative Comparison: Equine Genital Tissues Under Uniaxial Loading
… male and female equine genital tissues through uniaxial tensile testing, with strain measurements obtained via digital image correlation. Dog-bone-shaped tissue specimens were excised from mares and geldings (n=23 from female tissues and n=42 from male tissues) with all specimens aligned along …

Uniaxial Strain Effect on Graphene-Nanoribbon Resonant Tunneling Transistors
… dissertation has been to study the effect of the uniaxial strain on the graphene nanoribbon resonant tunneling transistors (RTTs). The uniaxial strain may be induced either by an external stress applied to the graphene in a particular direction or by a substrate due to deposition of graphene on …

Efficient finite element modeling of WT sections subjected to uniaxial tension
Present design specifications for statically loaded tension members do not consider the effects of connection eccentricity as it induces bending in statically loaded members. Previous experimental tests conducted at West Virginia University [WVU] have shown that connection eccentricity induced …

The effect of uniaxial stress on the electron paramagnetic resonance of ruby
The effect of uniaxial stress on the EPR lines in 0.05% ruby may be described by the addition of a term to the spin Hamiltonian of the form. The components of the G-tensor may be ascertained from the shift of the resonance field with strain at various directions in the crystal as a function of the …
