Shale gas is a promising energy source offering additional security over concerns of fossil fuel depletion. Injecting CO2 into depleted shale reservoirs might provide feasible solution for storage and enhanced recovery. However, strain caused by the injection as well sequestration in reservoir needs to be considered during production. For this purpose, paper examines adsorption capacities, CO2-induced swelling, He-induced shales at 0–16 MPa 35–75 °C. The maximum excess different temperatures...
Fretting wear is a kind of material damage in contact surfaces caused by microrelative displacement between two bodies. It can change the profile surfaces, resulting loosening fasteners or fatigue cracks. Finite element method an effective to simulate evolution fretting process. In most studies wear, coefficient friction was assumed be constant simplify model and reduce difficulty solving. However, test showed that variable related number cycles. Therefore, this paper introduces as function...
Urban search and rescue robots are designed to locate save the survivors in earthquake areas. This paper presents a novel robotic system, which is aimed spread narrow gap open new space release buried from pressure as temporary supports. Also, robot can make spaces for working moving courses other tools. consists of spreader tool mobile unit. The drived by hydraulic actuator spreads 3cm 20cm with 1000kg payload. unit multi-tracked mechanism enforce mobility on rugged terrains. experimental...
In this work, a FGM thick wall tube under both thermal and mechanical loadings is studied by referring to the Mori-Tanaka method. The assumed be made of two distinct linear elastically deformable materials equipped with unique volume fractions. Specially, its material parameters are firstly evaluated in scheme method which can more accurately depict effective properties FGMs composites. Later, we derive ordinary differential equation (ODE) displacement along radial direction, based on...
This study aims to investigate the effects of case depth and hardness distribution carburizing on rolling contact fatigue (RCF) properties G20CrNi2MoA steel under deeper conditions. Four groups specimens different depths are prepared subjected RCF tests. A 2D finite element model based continuum damage mechanics is developed further analyze these two factors. As carburized increases, life first increases then decreases. The optimum approximately one‐quarter thickness specimen. gentler due a...
In multi-component flow and/or thermal flows, when the diffusion coefficient of advection–diffusion equation is relatively small, relaxation in lattice Boltzmann method will be close to 0.5, which lead numerical instability. The stability conditions become more severe, there are high gradient regions computational domain. order improve simulate scalar transport complex flow, a hybrid regularized collision operators and dynamic filtering suitable for convection-diffusion proposed this paper....
In aircraft manufacturing, riveting is one of the most important connection ways to fasten sheet metal parts. The riveted single strap butt joints are mainly used in load-bearing components such as fuselage and wing panels. quality fatigue performance directly affect reliability safety aircraft. this paper, under assumption constant temperature, strengthening mechanism interference-fit introduced based on elastic-plastic mechanics fracture mechanics. On basis, finite element (FE) models with...
Crack initiation and propagation is a long-standing difficulty in solid mechanics, especially for elastic brittle materials. A new type of transparent sandwich structure, with magnesium-aluminum spinel ceramic glass as the outer was proposed this paper. Its dynamic response studied by high-speed impact experiments numerical simulations peridynamics under loads, simultaneously. In experiments, light gas cannon used to load projectile 180 m/s, front impacted structure. simulations,...
