Batch-compatible Integration of Nanowires with Uniaxial Micro Tensile Testing Platforms
… employ microelectromechanical systems based tensile loading platforms. The nanoscale specimens are typically mounted manually onto the loading platforms with external integration techniques so the boundary conditions have random variations, complicating the experimental measurement of the …

Mold design, fabrication and tensile testing of EMBed-812, a tissue embedding epoxy resin
… of precision. This thesis focuses on performing tensile tests to determine some of the material properties-elastic modulus, ultimate tensile strength, yield strength-of the epoxy resin used to embed fixed brain tissue. These results will be used in cutting models and help guide the development of …

Domes and Crosses: Exploiting synergies in two methodologies for biaxial tensile testing of membrane tissues
Biaxial tensile testing is the preferred method for mechanically testing membranous tissue as it can capture the tissue load response more holistically than uniaxial methods. There are two dominant approaches within the field of biaxial tensile testing: planar and bulge. Both methods can induce a …

Design of fixtures and specimens for high strain-rate tensile testing on a drop tower
… and specimens to allow the machine to perform tensile tests. Two major design options were considered and analyzed using engineering mechanics and finite element analysis. The design selected used a double dog-bone specimen bent into a "U"-shape and impacted by a weighted force sensor with a …

Elevated temperature mechanical properties and corrosion characteristics evaluation of alloy Ht-9
This thesis presents the results of tensile testing, stress corrosion cracking (SCC) and localized corrosion studies of Alloy HT-9, which is currently being considered as a target structural material for transmutation applications. The results of tensile testing indicate that the yield strength and …

Characterization of mechanical properties of fused deposition modeling manufactured polycarbonate composites
… Modeling (FDM) method. The approach comprises of tensile testing of FDM manufactured samples following the ASTM D 638-03 and ASTM D 3039-00 standards. This gives the mechanical properties of either individual polycarbonate fibers or the lamina, which serves as input to a mathematical formulation …

Rheometric measurement of hydrogel toughness
… such as toughness. However, traditional tensile testing methods do not work for such materials due to the intrinsic softness of the material. We present a novel method for measuring fracture energy using a rheometer and show it is broadly consistent with the pure shear test, a standard …
