Centrifuge experiment and numerical analysis of an air-backed plate subjected to underwater shock loading

Zhijie HUANG, Xiaodan REN, Zuyu CHEN, Daosheng LING

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 6,   Pages 1350-1362 doi: 10.1007/s11709-019-0559-x

Abstract: systematic centrifuge experiments and numerical studies are conducted to investigate the effect of shockThe second model to predict the time history of shock wave pressure from an underwater explosion wasSystematic numerical studies are performed to investigate the effect of the accumulated shock impulseThe numerical and experimental results suggest that the peak strains are strongly dependent on the accumulatedshock impulse.

Beneficial effect of arginine vasopressin on hemorrhagic shock through improving the vascular reactivity

LI Tao, YANG Guangming, XU Jing, LIU Jiancang, LIU Liangming

Frontiers of Medicine 2008, Volume 2, Issue 3,   Pages 248-254 doi: 10.1007/s11684-008-0047-5

Abstract: The vascular reactivity and calcium sensitivity were decreased following hemorrhagic shock.Arginine vasopressin (AVP) was beneficial to endotoxic, infectious/septic and hemorrhagic shock.found that Rho kinase played an important role in the occurrence of calcium desensitization following shockSo we hypothesized that AVP might have beneficial effect on shock via activation of Rho kinase to regulateHemorrhagic shock (40 mmHg for 2 h) Wistar rats were adopted to observe the effects of small dose of

Accumulated damage process of thermal sprayed coating under rolling contact by acoustic emission technique

Jia XU,Zhen-yu ZHOU,Zhong-yu PIAO

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 3,   Pages 227-232 doi: 10.1007/s11465-016-0395-9

Abstract:

The accumulated damage process of rolling contact fatigue (RCF) of plasma-sprayed coatings was investigatedThe influences of surface roughness, loading condition, and stress cycle frequency on the accumulatedAE signal characteristics were investigated to reveal the accumulated damage process.Heavy load would aggravate the accumulated damage status and induce surface fracture.Frequent stress cycle would aggravate the accumulated damage status and induce interface fracture.

Simulation of Rock Shock Damage Evolution Law with Numerica lManifold Method

Liu Hongyan,Lv Shuran,Qin Siqing

Strategic Study of CAE 2007, Volume 9, Issue 3,   Pages 92-96

Abstract:

According to the definition of the damage variable basing on the stress wave attenuation, this paper makes an expansion to the original numerical manifold program which can only be used to simulate the body deformation of the linear elastic constitutive under the invariable load by adopting the stress wave attenuation damage model. The damage evolution law in the one-dimensional rock long bar under the impact load is simulated with the expanded program, and the damage evolution curves of the different points and the total material are obtained. The simulation results show that the increase of damage mainly happens in the initial time of the impact load, and with the time going on, the intensity of the stress wave attenuates and the damage do not increase evidently.
