TL;DR: In this article, the authors present results of an ongoing investigation undertaken by the authors concerning the mechanical and physical properties of fiber reinforced concrete ground slabs at an industrial scale and present results concerning the punching shear failure of a 6.00 m × 6.15 m synthetic fiber reinforced ground supported slab.

TL;DR: In this paper, the authors carried out finite-difference time-domain simulations, with a specially designed boundary condition, on pure evanescent waves interacting with a lossy left-handed material (LHM) slab.
Abstract: We carry out finite-difference time-domain simulations, with a specially designed boundary condition, on pure evanescent waves interacting with a lossy left-handed material (LHM) slab. Our results provide the full-wave numerical evidence for the amplification of evanescent waves inside a LHM slab of finite absorption. The amplification is due to the interactions between the evanescent waves and the coupled surface polaritons at the two surfaces of the LHM slab and the physical process can be described by a simple model.

TL;DR: In this article, the bending analysis of reinforced concrete slabs by the finite element method is presented, which concentrates on the nonlinear behavior due to progressive cracking of a slab and does not include post-yield behavior.
Abstract: The bending analysis of reinforced concrete slabs by the finite element method is presented. The analysis concentrates on the nonlinear behavior due to progressive cracking of a slab and does not include post-yield behavior. The Branson and Beeby methods are explored for estimating the rigidity of a cracked concrete region. The latter is found to yield better results. In order to deal with cracking in any arbitrary direction, suggestions are made for the transformation of the matrix of flexural rigidities and for the determination of equivalent steel areas with respect to the orientation of the cracks in a region. Some results are presented to demonstrate the proposed method.

TL;DR: The outer topographic rise seaward of many island arcs can be explained in terms of a bending moment applied to the oceanic lithosphere either by the downgoing slab to which it is attached or by modest shear stresses acting along the underthrusting plate boundary as mentioned in this paper.
Abstract: Summary
The outer topographic rise seaward of many island arcs can be explained in terms of a bending moment applied to the oceanic lithosphere either by the downgoing slab to which it is attached or by modest shear stresses acting along the underthrusting plate boundary. The existence of the outer rise does not require large horizontal compressive stresses to maintain it.

TL;DR: In this paper, the authors calculated the mineralogical properties of the Earth's mantle and the lithological units constituting the subducting oceanic slabs within a wide range of P-T conditions within the CaO-FeO-MgO-Al2O3-SiO2 system, except for the basalt top-layer of a slab.
