In order to determine the influence of different factors on CO2 huff-and-puff displacement effect, a experiment was carried out with Chang 6 tight sandstone samples in Ordos Basin as research object. Combined nuclear magnetic resonance technology, influences injection pressure, cycle numbers and soaking time effect were evaluated, optimal parameters optimized. The microscopic degree crude oil production scale pores quantitatively characterized. results show that pressure have significant...
Pneumatic artificial muscles (PAMs) are an extensively investigated type of soft actuator. However, the PAM motions have been limited somewhat to uniaxial contraction and extension, restraining development PAMs. Given current strong interest in robotics, PAMs gaining renewed attention due their excellent compliance ease fabrication. Herein, under inspiration elephant trunk, a family bending helical extensile (HE-PAMs)/helical contractile (HC-PAMs) was proposed analyzed. Through both...
This paper describes a new concept of an active honeycomb structure for morphing wingtip applications based on tubular inflatable systems and auxetic cellular structure. A work-energy model to predict the output displacement versus input pressure is developed together with finite element formulation, results are compared data obtained from small-scale example honeycomb. An analysis hysteresis associated multiple cyclic loading also provided, design considerations larger-scale demonstrator made.
Aluminum alloy 6082 (AA6082) is widely used in the production of industrial structural parts due to its light weight and good mechanical properties. However, such components are often accompanied by peripheral coarse grain defects poor surface hardness wear resistance. A nanostructured layer was developed on AA6082 through Surface Mechanical Attrition Treatment (SMAT) improve Thermal stability other features were investigated after annealed from 150 °C 350 °C. The experiment results showed...
Zirconia (ZrO2) implants have shown promising outcomes in the restoration of tooth loss. However, discrepancy between elastic modulus ZrO2 and alveolar bone can cause a stress shielding effect at bone-implant interface, leading to progressive damage possibly resulting clinical failure implant treatment. Functionally graded porous present solution this issue. Triply periodic minimal surfaces (TPMS) attracted growing interest for their ability create 3D interconnected continuous pore...
Such as flying creatures, morphing aircraft can expand their aerodynamic flight envelopes by changing shapes, significantly improving the scope of application and efficiency. A novel 3D Zero Poisson's Ratio (ZPR) honeycomb structure is designed to meet flexible deformation requirements aircraft. The ZPR deform in three principal directions with smooth borders isotropic. Analytical models related uniaxial shear stiffnesses are derived using Timoshenko beam model validated quasi-static...
Formation of periodical fracture surface marks in the dynamic can only be observed, mainly ideally brittle amorphous materials and under mode I loading conditions. Here authors report on observation elastic-wave patterns nanoscale that form compressive process a Ni-based alloy which is less-brittle metal with an appreciable ductility. The formation nanowaves evidenced via creation microbranching instability as well interaction crack front material inhomogeneities, i.e., microcracks.
The honeycomb sandwich structure is widely used in energy-absorbing facilities because it lightweight, has a high specific stiffness and strength, easy to process. It also dynamic mechanical characteristics such as impact resistance energy absorption. To explore the influence of Poisson’s ratio on local resistance, this paper compares analyzes series cores with different ratios under spherical projectile at speeds. Three typical honeycombs negative/zero/positive Poisson (re-entrant hexagon,...
In this paper, a nanocrystalline surface layer without impurities was fabricated on Ti-6Al-4V alloy by means of mechanical attrition treatment (SMAT). The grain size in the is about 10 nm and morphology displays random crystallographic orientation distribution. Subsequently, low-temperature boriding behaviors (at 600 °C) SMAT sample, including phase composition, microstructure, micro-hardness, brittleness, were investigated comparison with those coarse-grained sample borided at 1100 °C....
