Diagonal Tension Testing of Interlocking Compressed Earth Block Panels
<p>This thesis examines the use of diagonal tension (shear) testing to determine factors affecting shear strength of Interlocking Compressed Earth Block (ICEB) panels. This work expands on the current information available about strength properties of ICEB assemblies, which are dry-stacked, as …

Design and use of a fixed-end low-load material testing machine
The purpose of this low-load material testing machine is to provide students an opportunity to perform basic material tests on their own instead of watching a lab technician, thus improving the student's lab experience. The machine proposed is small, low cost, and easy to manufacture, assemble, and …

Computational Stress and Deformation Analysis of Mammary Prosthesis
… the breast implants was developed through axial tension testing, while linear and non-linear breast tissue models were assumed based on smooth muscle. These material models were to develop axisymmetric finite element models to determine the stresses in the implant walls under tissue loading. The …

The Comparison of the Tensile, Shear-Peel, and Torque Orthodontic Bond Strength Test Methods Performed on a Resin and Two Glass Ionomer Cements
… tensile, shear-peel, and torque bond strength testing methods using a commercially available resin (R), light-cured (LC), and chemically cured (CC) glass ionomer. Sixty-three bovine incisors were randomly divided into three groups. Stainless steel incisor brackets were bonded to the prepared …

Bauschinger effect in Nb and V microalloyed line pipe steels
… effect was measured during compression-tension testing for the same steel conditions. The yield stress drop during reverse deformation has been found to increase with an increase in forward pre-strain, dislocation density and particle number density within the effective particle diameter …

The design, analysis, construction, and testing of a multifunctional composite satellite structure
… in the production of a space-worthy component. Testing was preformed to verify the analysis and design. Testing included flatwise tension testing to verify integrity of the honeycomb bonding, tensile testing to verify stiffness calculations and experimentally determine the failure load for the …

Energy Absorption and Dynamic Behaviors of Architectured Interpenetrating Phase Composites
… two interpenetrating cellular solids. Through tension testing, we demonstrate that combined interphase action results in damage delocalization and an order-of-magnitude improvement in strain-to-failure over the fully dense base material. These experiments validate a micromechanics-based model …

Influence of the Interphase on the Mechanical Properties of Nylon 66 Composites
… using both microscopic and macroscopic testing techniques. The objective was to determine how different interphase morphologies affect the adhesion and properties such as damping, ultimate stress and strain, and modulus of the composite. This was accomplished using a modified fiber …

Multiscale Microstructural Investigation of the Ductile Phase Toughening Effect in a Bi-phase Tungsten Heavy Alloy
… of WHA deformation through in-situ uniaxial tension testing. The contributions of purposefully introduced microstructural anisotropy and its contribution to texturing and boundary conformations is discussed, and an emphasis has been placed on the study of the interface between the dissimilar …

Surface Orientation Dependent Corrosion Damage and Temperature Dependent Mechanical Property Degradation of Sensitized AA5083-H116 Alloys
… examination and subsequent mechanical (tension and tensile creep) testing. To connect the laboratory studies to the field exposure, Novelis 5083-H116 was sensitized at 100°C; dog bone samples were created and exposed for two years in a beach environment to investigate possible …

Tensile Properties of Loblolly Pine Strands Using Digital Image Correlation and Stochastic Finite Element Method
… of wood strands with respect to these variables. Tension testing incorporating digital image correlation (DIC) was employed to measure the MOE and UTS of earlywood and latewood bands sampled from growth ring numbers 1-10 and growth ring numbers 11-20. A similar technique adjusted for strand size …

The tensile performance of closed cell foam expansion joints: a study on the deleterious effects of compression set
… away from these foams, as reported failures in tension have caused its reliability to become suspect. In determining the cause of these tensile failures, the permanent loss in thickness due to load cycling, also known as compression set, was thought to be a likely contributor. This loss of …

Biomechanical Responses of Human Surrogates under Various Frontal Loading Conditions with an Emphasis on Thoracic Response and Injury Tolerance
… impacts. The rib cortical bone underwent coupon tension testing, while the whole ribs underwent bending tests intended to simulate loading from a frontal impact. The rib material properties accounted for less than 50% of the variation observed in the whole rib structural properties, indicating …

Scaling Effects on Damage Development, Strength, and Stress-Rupture Life on Laminated Composites in Tension
The damage development and strength of ply-level scaled carbon/epoxy composite laminates having stacking sequence of [+Tn/-Tn/902n]s where constraint ply angle, T, was 0, 15, 30, 45, 60, and 75 degrees, and size was scaled as n=1,2,3, and 4, is reported in Part I. X-radiography was used to monitor …
