In recent years, ExxonMobil has undertaken a comprehensive experimental and numerical program to characterize tensile strain capacity of welded pipelines under different operational, geometric and material property conditions. Key parameters affecting tensile strain capacity have been identified through sensitivity studies and used in a large-scale FEAbased parametric study to develop closed-fo...

In this paper, results of an investigation on the strain hardening responses of superalloy MP35N with two average grain sizes of 38 and 1 μm, during room temperature tensile testing are reported. The microstructural evolution of the deformed samples was studied using optical and transmission electron microscopy (TEM) techniques. The strain hardening behavior of the 38 μm material was rather sim...

The newly identified natural fabric from the tree of Sterculia urens was coated with Polymethyl methacrylate. The tensile properties of both the uncoated and Polymethyl methacrylate coated fabrics were studied. The tensile parameters such as maximum stress, Young’s modulus and % elongation at break were determined using a Universal Testing Machine. The effect of alkali treatment and the Polymet...

In the present study we have attempted to verify a theoretical model of grab versus strip strengths of fabrics [Textile Research Journal, 2003, 73(2), 165–171] through experimental investigation. Five different fabrics were included in this study, and three related parameters were investigated including the modulus ratio of the specimen (shear versus tensile moduli), the specimen gauge length a...

STRNKOVÁ JANA, NEDOMOVÁ ŠÁRKA, KUMBÁR VOJTĚCH, TRNKA JAN. 2016. Tensile Strength of the Eggshell Membranes. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(1): 159–164. The mechanical behaviour of eggshell membranes under tensile loading has been studied. Samples from diff erent bird species (hen, goose and Japanese quail) have been used. Samples were cut out of the m...

Tensile failure properties of single collagen fibrils were determined using our original tensile test method. Fibrils were directly isolated from the fascicles of mouse tail tendons. Both the ends of each fibril were wound onto the tips of two microneedles several times using micromanipulators. The fibril and tips were immersed in physiological saline solution. Then, the fibril was stretched to...

We have developed a novel tensile stage that can be used for in situ electron microscopy examination of the mechanical properties of "superelastic" materials. In our stage, one of the specimen clamps is replaced by a cylindrical roller, which when driven by a motor can easily stretch ("roll on") any specimen irrespective of its plastic properties. We have used the so-called Roll-o-meter in the ...

Mechanical response of E-glass/epoxy fiber reinforced composite was investigated in tensile loading. Different types of tabs were considered in order to evaluate their effects on the tensile strength of material. Specifically, two types of molded tabs and five types of bonded tabs were considered in the study. The influence of different amount of gripping pressures on failure mode and on tensil...

To study the adhesion of epoxy resin based endodontic sealers by determining the tensile bond strength and evaluating the effect of smear layer removal on the adhesion of the endodontic sealers. Root canals of freshly extracted mandibular first premolar teeth with single root canal, were instrumented by using rotary instrument The roots were prepared for adhesion by splitting them and embedding...
