Accurate determination of natural frequencies and mode shapes the rotating tapered Timoshenko beam is important in engineering practice. This paper re-examines free vibration beams using technique variational iteration, which relatively new capable providing accurate solutions for eigenvalue problems a quite easy way. Natural with linearly varying height as well width are investigated via two numerical examples, compared results published literature where available. Since method constitutes...
A one-step new general mesh free scheme, which is based on radial basis functions, presented for a viscous wave equation with variable coefficients. By constructing simple extended function, it can be directly applied to propagation by using the strong form-based collocation method. There no need deal time-dependent particularly. Numerical results coefficients show that proposed method accurate solutions.
Four salophen complexes were prepared using the spiral gas–solid two-phase flow (S-GSF) technique and applied to catalyze AP, reducing high-temperature decomposition peak of AP its activation energy.
Tapered beams constitute functionally graded materials that are widely used in various engineering fields. The vibrational characteristics of tapered made axially varying investigated via variational iteration method. Natural frequencies and corresponding mode shapes examined, calculated compared with results provided by previous researchers using other approximate methods. efficiency accuracy this technique demonstrated. effect nonhomogeneous material distribution, taper ratio as well...
The Zn–BTC, Co–BTC and Zn–Co–BTC series MOFs were prepared by using the GSF device applied in catalytic thermal decomposition of AP to change high-temperature peak AP.
One new laurane-type sesquiterpene, 10-hydroxyepiaplysinol (1), along with two known related sesquiterpenes, epiaplysinol (2) and ar-bisabol-9-en-7,11-diol (3), one carotenoid metabolite, loliolide (4), were obtained from the red alga Laurencia tristicha. Their structures elucidated based on comprehensive spectroscopic data analysis. Of compounds, 4 was isolated genus for first time. Additionally, antioxidant activities of eleven sesquiterpenes L. tristicha evaluated.
This paper is concerned with the flexural vibration analysis of rotating Timoshenko beams by using variational iteration method (VIM). Accurate natural frequencies and mode shapes under various rotation speeds rotary inertia are obtained. The VIM solutions verified comparing some existing results in literature as well validated from a comparison study experimentally measured ones. High accuracy efficiency demonstrated use only small number steps required for convergence first to tenth beam.
Abstract With the wide application of extended reach wells and horizontal wells, geological conditions faced during drilling process have become increasingly complicated, resulting wellbole collapse problem has serious. Based on an L-1 well, this study provides a method for calculating pressure considering influence formation hydration. This is used to obtain stress distribution around well situation at 4100 m underground. The wellbore stability can be evaluated by method. factors affecting...
Post-discharge coping difficulty presents a significant challenge for mothers of preterm infants. The readiness hospital discharge and parenting self-efficacy are crucial factors influencing post-discharge difficulty. However, the pathways through which these impact remain unclear. This study aims to investigate on mediating role among A prospective involving 462 infants from six tertiary hospitals in Shandong Province was conducted. Mothers were evaluated day (using Baseline characteristics...
Abstract In the early stages of exploration, with only a limited amount data available, it is difficult to evaluate reservoir and optimize sequence development plan. The score system often used rank based on multidisciplinary factors that combine geology, production, economics. However, current methods are widely employed classify reservoir, such as analogy or single parameter, qualitative inaccurate, especially for carbonate gas reservoirs complex geological conditions. this study, we...
The microscopic differences in characteristics and formation mechanism of shale oil reservoirs the upper lower sweet spot sections Lucaogou Formation Jimsar Depression, which has been identified as a national demonstration area China, are still unclear. In this study, main controlling factors reservoir different spots were specified based on core observation, thin-section X-ray diffraction, Rock-Eval, fluorescence hydrocarbon inclusions, temperature measurement saline inclusions. Results...
This paper focuses on the stability of high-level radioactive waste (HLW) in proposed clay rock Tamusu area China. The in-situ stress as well variational characteristics ambient temperature caused by nuclide decay during HLW storage should be noticeable. A series thermal property tests and thermo-mechanical coupled strength (T-M) samples target formation are carried out. Then surrounding an under combination heat release from is simulated analyzed numerical method. Thermal properties...
Abstract This study focused on the deep tight sandstone reservoir (DTSR) of fourth member Shahejie Formation in Bozhong Sag, Bohai Bay Basin, a special type reservoir. To reveal diagenesis and evolution area, cores observation, thin section identification, scanning electron microscopy, grain size analysis, petrophysical properties measurements are available to analyze mechanics densification processes.
