Analysis and calculations were performed on tensile members, compression members,connection, deflections that occur standard SNI 7973 : 2013. The needs be analyzed for its overall strength so function building can maximized. results research obtained value in carrying was due connection wi...

We present in situ transmission electron microscope tensile tests on focused ion beam fabricated single and multiple slip oriented Cu tensile samples with thicknesses in the range of 100-200 nm. Both crystal orientations fail by localized shear. While failure occurs after a few percent plastic strain and limited hardening in the single slip case, the multiple slip samples exhibit extended homog...

BACKGROUND The purpose of this study was to compare the shear and tensile bond strength of three adhesive systems with increasing concentrations of filler for bonding brackets. MATERIALS & METHODS The study was carried out on 120 extracted human premolars; randomly divided into six groups, three groups for shear bond strength & three for tensile bond strength, each subgroup consisting of 20 t...

No reports have described experiments designed to determine the strength characteristics of spinal nerve roots and rami radiculares for the purpose of explaining the complexity of symptoms of medullary cone lesions and cauda equina syndrome. In this study, to explain the pathogenesis of cauda equina syndrome, monoaxial tensile tests were performed to determine the strength characteristics of sp...

The purpose of this study is to compare the differences between Shear compression load using shear compression loads tester (858 Bionix, MTS, USA) with fixed screws in the force of 30 N·cm using in four different fastening methods with implanting(N=5) fixture an abutment. As a result of the experiment, the compression load of YI Implant which is the compression load of Internal octagon connecti...

STUDY DESIGN Biomechanics of human intervertebral discs before and after nucleotomy. OBJECTIVE To noninvasively quantify the effect of nucleotomy on internal strains under axial compression in flexion, neutral, and extension positions, and to determine whether the change in strains depended on degeneration. SUMMARY OF BACKGROUND DATA Herniation and nucleotomy may accelerate the progression ...

Compression tests carried out on aluminium specimens showed that when the die was rotated the compression load dropped. A slab method is employed to examine this process. The load reduction is explained by the deviation of friction vector due to the relative circumferential movement between the die and the material. This mechanism is incorporated into a theoretical model and an expression is de...

Abstract The formation of a reliable joint between large number aluminum strands for battery applications is crucial in automotive industry, especially the technology autonomous vehicles. Therefore, this study, mechanical deformations and diffusion patterns mating interface ultrasonic welding were investigated using molecular dynamics simulations. Furthermore, microscopic observations joints fr...

The aim of the present study is to investigate the effect of variation of polypropylene fibres ranging from 0.1% to 0.4% along with 0.8% steel fibres on the behaviour of fibrous concrete. The mechanical properties of the concrete such as compressive and tensile strength have been investigated. The result shows that addition of polypropylene fibre has a little effect on the compressive strength,...

In the current research, a three-dimensional finite element model was considered to predict the mechanical behavior of Single Wall (SWCNTs) and Multi Wall Carbon Nanotubes (MWCNTs). Assuming the nonlinear elastic behavior of C-C bond in large strains, hyperelastic models were considered. Literature review revealed that the material parameters of the hyperelastic models have been determined from...
