Study of material removal behavior on R-plane of sapphire during ultra-precision machining based on modified slip-fracture model

引用

Nanotechnology and Precision Engineering 2020年第3期3卷 141-155页

作者： Suk Bum Kwon Aditya Nagaraj Hae-sung Yoon Sangkee min Department of Mechanical Engineering University of Wisconsin-Madison1513 University AvenueMadisonWI 53706United States of America School of Aerospace and Mechanical Engineering Korea Aerospace University76 Hanggongdaehak-roDeogyang-guGoyang-siGyeonggi-do 10540Republic of Korea

In this paper, the modified slip/fracture activation model has been used in order to understand the mechanism of ductile-brittle transition on the R-plane of sapphire during ultra-precision machining by reflecting direction of resultant force. Anisotropic characteristics of crack morphology and ductility of machining depending on cutting direction were explained in detail with modified fracture cleavage and plastic deformation parameters. Through the analysis, it was concluded that crack morphologies were mainly determined by the interaction of multiple fracture systems activated while, critical depth of cut was determined by the dominant plastic deformation parameter. In addition to this, by using proportionality relationship between magnitude of resultant force and depth of cut in the ductile region, an empirical model for critical depth of cut was developed.

Super Strong and Tough Elastomers Enabled by Sacrificial Segregated Network

引用

Chinese Journal of Polymer Science 2021年第3期39卷 377-386,I0008页

作者： Yong Zhu Lai-Yun Wei Xuan Fu Jun-Qi Zhang Ling-min Kong Guang-Su Huang Jin-Rong wi State Key Laboratory of Polymer Materials Engineering College of Polymer Science and EngineeringSichuan UniversityChengdu 610065China

The integration of high strength and toughness concurrently is a vital requirement for elastomers from the perspective of long-term durability and reliability. Unfortunately, these properties are generally conflicting in artificial materials. In the present work, we propose a facile strategy to simultaneously toughen and strengthen elastomers by constructing 3 D segregated filler network via a simple latex mixing *** as-fabricated elastomers are featured by a microscopic 3 D interconnected segregated network of rigid graphene oxide(GO) nanosheets and a continuous soft matrix of sulfur vulcanized natural rubber(NR). We demonstrate that the interconnected segregated filler network ruptures preferentially upon deformation, and thus is more efficient in energy dissipation than the dispersed filler network. Therefore, the segregated filler network exhibits better reinforcing effects for the rubber matrix. Moreover, the excellent energy dissipating ability also contributes to the outstanding crack growth resistance through the release of concentrated stress at the crack tip. As a result, the strength, toughness and fatigue resistance of the nanocomposites are concurrently enhanced. The methodology in this work is facile and universally applicable, which may provide new insights into the design of elastomers with both extraordinary static and dynamic mechanical performance for practical applications.

Journal of Sport and Health Science 2017年第4期6卷 447-453页

Purpose: The purpose of this study was to investigate the effects of obesity and aerobic exercise training on oxidant-antioxidant balance,neurotrophic factor levels, and blood-brain barrier(BBB) ***: Ten non-obese healthy men(body mass index min 3 times weekly for 8 weeks at 70% heart rate reserve. Blood samples were collected to examine oxidant-antioxidant balance(reactive oxygen species(ROS) and superoxide dismutase(SOD) activity levels), neurotrophic factors(brain-derived neurotrophic factor(BDNF), nerve growth factor, and glial cell line-derived neurotrophic factor levels), and BBB function(S100βand neuron-specific enolase(NSE) levels) before and after exercise ***: The obese group showed significantly greater changes than the non-obese group in serum ROS(-0.46 ± 0.31 mmol/L vs.-0.10 ±0.17 mmol/L,p=0.005),serum S100 p levels(-8.50 ± 5.92 ng/L vs.-0.78 ± 5.45 ng/L,p=0.007),and serum NSE levels(-0.89 ± 0.54 μg/L vs.-0.01 ± 0.74 μg/L,p= 0.007) after training. At baseline,the obese group showed significantly higher serum ROS and S100β levels and significantly lower serum SOD activity and BDNF levels than the non-obese group(p with baseline(p < 0.05).Conclusion: These results suggest that obesity can reduce serum neurotrophic factor levels and can induce BBB dysfunction. On the other hand,aerobic exercise can improve an oxidant-antioxidant imbalance in obese subjects and limit BBB dysfunction.

Obesity promotes oxidative stress and exacerbates blood-brain barrier disruption after high-intensity exercise

Journal of Sport and Health Science 2017年第2期6卷 225-230页

Purpose: The purpose of this study was to investigate the effects of obesity and high-intensity acute exercise on oxidant-antioxidant status,neurotrophic factor expression, and blood-brain barrier(BBB) ***: Twenty-four healthy, untrained men(12 non-obese(mean 14.9% body fat) and 12 obese subjects(mean 29.8% body fat)) performed20 min of continuous submaximal aerobic exercise at 85% maximal oxygen consumption. Blood sampling was performed to examine the oxidant-antioxidant status(reactive oxygen species(ROS) and superoxide dismutase(SOD)), neurotrophic factors(brain-derived neurotrophic factor(BDNF) and nerve growth factor(NGF)), and BBB disruption(S100β and neuron-specific enolase) before and after acute ***: The obese group showed significantly higher pre-exercise serum ROS levels and significantly lower pre-exercise serum SOD levels than the non-obese group(p with pre-exercise levels in both the non-obese and the obese groups(p < 0.05). The obese group showed significantly higher serum ROS, BDNF, NGF,and S100β levels post-exercise compared to the non-obese group(p < 0.05).Conclusion: Our study suggests that episodic vigorous exercise can increase oxidative stress and blood neurotrophic factor levels and induce disruption of the BBB. Moreover, high levels of neurotrophic factor in the blood after exercise in the obese group may be due to BBB disruption,and it is assumed that oxidative stress was the main cause of this BBB disruption.
