Order to investigate the failure effect of textile reinforced concrete (TRC) plate under bending load, corresponding finite element model is established. By comparing numerical simulation results with experimental results, rationality and feasibility are verified, then crack extension TRC ultimate strain carbon analyzed. The mode slab load obtained, it found that has better reinforcement effect...

obtaining temperature distribution data of slabs under rolling is essential as the mechanical and metallurgical properties of the metal under this process vary with temperature. using the control volume method, a mathematical model is employed in this study to predict slab temperature in the hot roll process at mobarakeh steel company. the effects of different parameters including the heat resu...

The question whether classical solutions of the surface quasi-geostrophic (SQG) equation can develop finite-time singularities remains open. This paper presents new numerical computations of the solutions to the SQG equation corresponding to several classes of initial data previously proposed by Constantin et al. (Nonlinearity 7:1495–1533, 1994). By parallelizing the serial pseudo-spectral code...

Progressive collapse of reinforced concrete flat plate systems can be significantly influenced by the post-punching performance their slab–column joints under large deformations. This work presents a series static tests on four joint specimens with slab in-plane restraint. The effects different punching directions (upward and downward) embedded beams were studied. test results reveal that load-...

[1] We present a novel explanation for absolute trench-normal motions of slabs surrounding the Pacific. Rapid subduction-zone retreat on the eastern side of the Pacific and slow advance in the west can result from the large-scale asymmetric plate configuration. We use simple fluid dynamics to explain the mechanical background of this hypothesis, and we use the results of a simple finite differe...

S U M M A R Y Our understanding of mantle convection and the motion of plates depends intimately on our understanding of the viscosity structure of the mantle. While geoid and gravity observations have provided fundamental constraints on the radial viscosity structure of the mantle, the influence of short-wavelength variations in viscosity is still poorly understood. We present 2-D and 3-D fini...

The propagation of surface plasmon polaritons on metallic waveguides adjacent to a gain medium is considered. It is shown that the presence of the gain medium can compensate for the absorption losses in the metal. The conditions for existence of a surface plasmon polariton and its lossless propagation and wavefront behavior are derived analytically for a single infinite metal-gain boundary. In ...

In the study, a retrieval approach is extended to determine the effective dynamic properties of a finite multilayered acoustic metamaterial based on the theoretical reflection and transmission analysis. The accuracy of the method is verified through a comparison of wave dispersion curve predictions from the homogeneous effective medium and the exact solution. A multiresonant design is then sugg...

In this paper, the temperature distribution in a slab was investigated. A model based on Boltzmann transport equation without heat source simplified using Bhatnagar-Gross-Krook (BGK) approximation applied. This is an example of Lattice Method. The developed D2Q4 lattice arrangement for medium study. To obtain results, tested different cases: Two box-shaped slabs with boundary conditions, and T-...

We demonstrate the possibility of achieving enhanced frequency-selective near-field radiative heat transfer between patterned (photonic-crystal) slabs at designable frequencies and separations, exploiting a general numerical approach for computing heat transfer in arbitrary geometries and materials based on the finite-difference time-domain method. Our simulations reveal a tradeoff between sele...
