Faulting reductions indicate slab movements is greater than allowable.
Steady state solution at the end of consolidation is denoted as psteady: psteady = SMweight·Pinput, (5) Pinput is the pore pressure generated during input data based on phreatic lines or ground water flow calculation.

The intrinsic mechanisms are the materials inherent resistance to microstructural damage and cracking while the extrinsic mechanisms promote a reduction in the driving force (e.g., the local stress intensity) at the crack tip (termed crack tip shielding) mainly by appearance of crack bridging phenomena or microcracking (Fig.1), [2,3].
On the basis of the obtained data the R-curve for the tested ceramics were plotted.

To verify the isolation bearing energy dissipation capacity after single ring optimization, the overall finite element models of isolation bearing before and after optimization are respectively set up (see Figure 8); use powerful ANSYS nonlinear analysis function to impose Fig.7 Hysteresis loop area Fig.8 The finite element model of optimized sliding seismic isolated bearing surface constraints on the baffle side and bottom surface, impose reciprocating load on isolation bearing y direction, to conduct simulation analysis; introduce the data such as force and displacement calculated by ANSYS into drawing tools and get the bearing hysteresis curve figures Fig.9 Hysteresis curves before optimization Fig.10 Hysteresis curve of the optimized before and after optimization (as shown in Figure 9 and Figure 10).
This paper uses ANSYS software to simulate the seismic response of basic fixed structure and sliding isolated structure as well as compare the earthquake reduction effect.

Introduction Magnesium alloys, having some excellent properties such as low density, high specific strength and stiffness, have received more concerns as very attractive materials for many industrial applications, especially in aerospace and automotive industries, from the viewpoint of high efficiency, saving energy, minimizing the weight of structural elements and reduction of the environmental loads to the globe.
Experimental data in this figure were plotted by the classification of two modes with the observation of crack initiation site, that is, specimens in which the Region I was observed at crack origin are indicated with a solid or semi-solid mark and the others not observed the Region I are indicated with an open mark.

In particular, components manufactured with thermoset pre-impregnated materials enable significant weight reduction, and so important fuel saving.
Deviations occurring for the [0/0] layup are due to fibre angle detection issues and to a severe filtering of the data.

Sound absorption materials from adding organic and inorganic waste fiber materials have received attention to address due to many advantages such as low price, high efficiency, waste reduction, biodegradability, eco-friendliness and abundance.
As the results of adding organic and inorganic fiber into the natural rubber compounds affects to the curing time, viscosity and rheology of rubber composite samples as data tabulated in Table 3.

The results indicated that the well trained ANN can accurately predict the ETC of the concrete hollow brick which matches very well with data obtained from the commercial FVM CFD.
In addition, relevant information was obtained, helping holed bricks producers to obtain better bricks for energy savings and energy consumption reductions in buildings.

This allows the reduction of the energy intensity of the test, the separation of the two air streams allowing any differentiation of their value, and the autonomous operation of the tested heat exchanger using its own control system [17, 18].
The obtained test results enable the formal qualification of the tested devices to applications complying with the technical requirements, and they also provide data enabling the optimum selection of the device to the constructed ventilation system.
