The effective strength of the socket part (threaded hole at both end of pole) at the joint constructed by two poles and one nipple of artificial graphite electrodes was evaluated by using finite element method (FEM) and measured under the uniaxial tension loading. The stress distribution at the socket was analyzed as a function of length of nipple using FEM. The stress at supposed fracture

2019/2/21Development of artificial joints is a great progress for joint replacement operations of human being, but the short longevity of prostheses has concerned both industries and researchers since the advent of modern implants. Thus, continuous improvements have been made alongside the clinical applications. The methodologies to inspect the potential properties of new designs have also seen

2017/10/31The chemical and morphological characteristics of materials released under chemical and physical stress by different rubber granulates used as infill materials in synthetic turf (recycled scrap tires, natural rubber, and a new-generation thermoplastic elastomer) were compared.The headspace solid-phase micro-extraction GC-MS analysis evidenced that at 70 C natural rubber and

Modified Inverted Nipple Correction Technique That

An inverted nipple is a congenital breast deformity commonly seen in women in which the nipple is partially or entirely buried under the areola surface. 1 It can be present unilaterally or bilaterally. Park 1 reported that the prevalence of congenital inverted nipples was 3% among the 1625 subjects examined.

Arthroplasty of the Hand: Radiographic Outcomes of

The radiographic abnormality rate for MCP joint arthroplasty was 41.2% (7/17) compared with 66.7% (20/30) for PIP joint arthroplasty (). Table 2 summarizes the radiographic abnormalities. Forty-one implants showed a symmetric rim of lucency of less than 1 mm surrounding the distal stem with a sclerotic margin that appeared on the first set of postoperative radiographs.

Fuzzy logic model for the prediction failure analysis of

In this study, stress values were examined in pin/bolt connected composite plates which were applied preload and non-preload moment. Composite plates were produced with different curing cycles and geometric dimensions. Failure analysis of composite plates was carried out by applying different preload moments. The results obtained from experimental study were processed using fuzzy model.

• Commonly caused by insufficient nursing, use of artificial nipple (e.g. pacifier), fatigue or maternal stress • Encourage woman to breastfeed often (8-10 times daily), eat well, get additional rest, drink lots of fluids and take prenatal vitamins and iron supplements

Graphene‐Based Antimicrobial Biomedical Surfaces

Later Liu et al. 10 compared the time and concentration dependent antimicrobial activity of graphite, graphite oxide, GO and rGO dispersion against E. coli. The highest antibacterial activity was observed with GO, which inactivated 69.36.1 % of bacterial cells in comparison to graphite, graphite oxide, and rGO where 26.14.8 %, 15.03.7 % and 45.94.8 % of killing efficiency were observed

Corrosion Crack Nucleation Mechanism in the Welded

After detecting residual stress, the average value of surface residual stress detection results of three corroded specimens in each group is referred to as the analysis data of residual stress. Thus, evolution laws of surface transverse residual stress distribution of welded structures are shown in Figure 7 .

An improved case based reasoning method and its

2020/4/17In the high speed milling process, the accurate predictions of surface roughness and residual stress can avoid the deterioration of machined surface quality. But it's hard to estimate the surface roughness and residual stress under different tool wear status and cutting parameters. In this work, a novel intelligent reasoning method-improved case based reasoning (ICBR) was proposed to predict

The effective strength of nipple in the joint part constructed by two poles and one nipple as artificial graphite electrodes was investigated in the uniaxial tension loading. The theoretical stress distribution of nipple was analyzed using the finite element method in the several types of distributed loads on the surface of each thread which was contacted with the thread of pole.

Diamond

Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.

The nickel coated graphite cathode decorated with silver nanoparticles (G/Ni/Ag). The hydrogen production efficiency of G/Ni/Ag was investigated in a joint experimental and computational effort. Ag decorated surface provides a preferable adsorption site for the O atom in water and direct interactions between water Hs and available surface Ni atoms promote water dissociation.

After detecting residual stress, the average value of surface residual stress detection results of three corroded specimens in each group is referred to as the analysis data of residual stress. Thus, evolution laws of surface transverse residual stress distribution of welded structures are shown in Figure 7 .

Elasticity: Stress and Strain

Note that this stress-strain curve is nonlinear, since the slope of the line changes in different regions. In the first part of the stretch called the toe region, the fibers in the tendon begin to align in the direction of the stress—this is called uncrimping.
