A Unified Correlation for Slip Factor in Centrifugal Impellers
Journal of Turbomachinery, 2005A method that unifies the trusted centrifugal impeller slip factor prediction methods of Busemann, Stodola, Stanitz, Wiesner, Eck, and Csanady in one equation is presented. The simple analytical method derives the slip velocity in terms of a single relative eddy (SRE) centered on the rotor axis instead of the usual multiple (one per blade passage ...

DETERMINATION OF SLIP‐FACTOR BETWEEN FRICTION SHIMS AND SHOT‐BLASTED STEEL SURFACES
ce/papers, 2023This paper presents the results of an experimental testing campaign performed to determine slip‐factor between the faying surfaces of shot‐blasted steel plates and state‐of‐the‐art friction shims.

Generalized Slip Operation Factor Considering Contribution of Secondary Slip Systems
Materials Today Communications, 2021Abstract Slip operation factor (SOF), which considers the effect of mechanical interactions between plastically “soft” and “hard” regions, is a function of the Schmid factor (SF) and critical resolved shear stress (CRSS). It is used as an indicator to efficiently predict the ease of slip operation of metal materials at the grain level.

Maturation Factors in Slipped Capital Femoral Epiphysis
Journal of Pediatric Orthopaedics, 1988Several maturation factors relative to growth and epiphyseal development were reviewed retrospectively in 191 patients with slipped capital femoral epiphysis, including bone age, height and weight, thyroid functions, sex hormone levels, and growth hormone levels. Seventy-one percent of 138 patients had weights above the 80th percentile. Active thyroid (

Mechanical Factors in Slipped Capital Femoral Epiphysis
Journal of Pediatric Orthopaedics, 1988We performed three-dimensional force analyses on the hips of 50 normal patients and 50 patients with slipped capital femoral epiphysis to determine if mechanical factors alone could account for slips. We found that slipped epiphysis patients have reduced resistance to shear because of increased body weight and a decreased neck shaft-plate shaft angle ...

Slip factors for slip-resistant connections made of stainless steel
Journal of Constructional Steel Research, 2019Abstract Stainless steels are becoming more and more popular as a construction material in both building and civil engineering structures, because of their high material strength, ductility and corrosion resistance. In this frame, the execution of slip-resistant connections made of stainless steel is necessary, e. g. in footbridges, facades etc.

Bilateral Slipped Capital Femoral Epiphysis
Journal of Pediatric Orthopaedics, 2007The primary goal in treatment of slipped capital femoral epiphysis (SCFE) is to prevent further slip by stabilizing the physis. Debate exists concerning prophylactic fixation of the uninvolved hip at presentation. Our goal was to determine predictive factors for a contralateral slip after presentation with a unilateral SCFE.

Background: Slip progression after in situ fixation of slipped capital femoral epiphysis (SCFE) has been reported as occurring in up to 20% of patients. We review SCFE treated with in situ single screw fixation performed at 2 hospitals over a 15-year period to determine the factors associated with slip progression.
