Tensile city
Tensile City is a story that provides the answer to the following question: II If we were to leap forward in time and visit a city of the future, what would learn about our contemporary city ? II The story unfolds when M.C., the main character, plans to undertake such a trek. The main reason for …

Tensile relaxation of bonded concrete overlays
… stress build up, cracking and even debonding. Tensile relaxation is the main mechanism of stress relief in concrete overlays. This results in less possibility of cracking and debonding. The research described in this study presents an analytical method of analysis. This method is based on tests …

Relative tensile strengths of chainmail weaves
… of chainmail were investigated by conducting tensile tests on both physical and simulated samples. Eight different ring diameters, four different ring gauges, four different weaves, and three methods of closure of the rings (butting, riveting, and welding) were tested. For both methods of …

Tensile Testing of Cold-Applied Joint Sealants
… The tests were carried out employing an Instron Tensile Testing Machine and unique fixtures designed at Virginia Tech to impart mechanical loading. In comparison to Sealant 2, the results demonstrated that Sealant 1 can withstand larger stresses. All the concrete samples failed due to adhesive …

A micromechanical model for predicting tensile strength
… and ceramic matrices under an applied global tensile loading is presented. The model is based on a Weibull statistical type of approach and incorporates eleven different variables to simulate different micromechanical failure phenomenon. Through the variables, the model incorporates such …

Tensile Fracture Mechanisms of Ferritic/martensitic Structural Materials
X-ray measurements and analysis not only support the hypothesis of the association between critical stress and critical interfacial strength, but also offer a new method to determine the true strain/stress behavior during deformation. This method is called the Universal Micro-structural …

Predicting and testing the tensile relaxation of concrete
Tensile relaxation is an important property in structural concrete members such as concrete overlays and patch repairs under sustained imposed restraint. Tensile relaxation helps in reducing tensile stresses in concrete which leads to mitigation of cracking in restrained concrete members. Normally, …

Characterizing tensile loading responses of 3D printed samples
… of samples manufactured through 3D printing. Tensile testing was performed on a number of 3D printed samples created through Fused Filament Fabrication (FFF). Printed samples were made from ABS or PLA plastic. A range of infill densities from 25% to 100% were tested for each material. …

Tensile Material Properties of Human Costal Cartilage Perichondrium
… The objective of this study was to evaluate the tensile material properties of human costal cartilage perichondrium at two loading rates for a range of subject demographics. Fifty-six (n=56) samples containing the fibrous layer and chondrogenic layer (i.e., two-layered samples) were fabricated …

Tensile Properties of Single Vaginal Smooth Muscle Cells
… experimental setup was used to perform tensile tests. Micropipettes were fabricated to serve as cantilever-type load cells, which were coated in cellular adhesive. Two pipettes applied tension to SMCs until adhesion between the cell and a pipette failed. During mechanical testing, images …

Mathematical Analysis of Compressive/Tensile Molecular and Nuclear Structures
… interactions as compressive (repulsive) and tensile (attractive) forces. Two particle interactions were considered, followed by a model of the dihydrogen molecule (H₂; two protons and two electrons). Dihydrogen was evaluated as two different types of compression/tension structures: a coaxial …

Confinement Limits For Tensile Lap Splices Under Static Loading
ABSTRACT In tension lap splices, the benefit provided to the lap by stirrups placed to intercept cracking due to bond splitting action is recognized by the American Concrete Institute (ACI 318-89) and the design recommendations of the ACI Committee 408, on which the American code provisions are …

A model treating tensile deformation of semi-crystalline polymers
… dependencies clearly demonstrate that the tensile deformation of semi-crystalline polymers follows a common scheme with changes in the mechanism at critical strains. <br> <br>Our measurements of true stress-true strain relationships were always accompanied by recovery tests. By carrying out …

Limiting factors of the tensile strength of aramid fibers
… crystallite orientation distribution and the tensile strength values that ranged between 3.5 and 4.0 GPa. Cyclic loading of individual, 10 mm long, as-spun filaments increased their initial moduli, all converging to 100 GPa for all fiber types when cycled to 90% of their respective tensile …

A system for high strain rate interruptible tensile tests
… specimen was loaded repeatedly. In the MSc, a tensile SHPB (TSHB) was designed with momentum trapping to conduct interruptible tests on specimens. This configuration makes use of tandem momentum traps, allowing for the system to be fully trapped without the need for precisely preset gaps, or …
