The i th eigenvalue, φi, represents the effective fractional reduction in load carrying area on planes that are perpendicular to the ith principal material direction as shown typically in Figure 1.
The Yi are eigenvalues of damage conjugate force tensor defied in Eq. (3) The J and H tensors are determined by available data on a single composite lamina, and K0 is the initial damage threshold.
The non-linear behavior and the stiffness reduction in the results are mainly due to the propagation of matrix cracking.
It can be due to the existence of errors in the used material data and simulation.
It shows that the stiffness reductions are not very large except for G13 at the interface layer which tend to zero and indicating the complete damage of the interface or shear delamination.

The XRD data were collected using a Siemens D5000 X-ray diffractometer (CuKa radiation), the SEM, TEM and DSC studies were performed using Jeol JSM 6400 (15eV), Phillips Tecnai F20 and SDT Q600 (the sample was 10.5mg at 10ºC/min) equipments respectively.
Because of ball milling, the preferred orientation in the XRD pattern has disappeared and the diffraction peaks become wider due to the crystal size reduction.
The width of Bragg peaks decreases indicating a reduction in internal stresses and a possible increase in the crystal size.
This is agreement with the XRD data.
The phase transformation is related with the crystalline defects accumulation and with the crystal size reduction during the milling process.

And the carbon emission and reduction in the green supply chain were focused on with the increased concerning on climate change in recent years [4,5,6].
That means there would be similar models for carbon emission assessment, and the representative product’s carbon emission could be expanded as the result of the whole enterprise, which could guide the emission reduction action.
This gives the informative base to analyze the carbon emission contributions of suppliers to the whole enterprise, and then, to evaluate the performance of green supply chain initiatives to the enterprise’s carbon emission reduction.
Carbon emission assessment method for household appliances Considering the actual situation of data statistic in enterprises in China, three phases, which were material phase, manufacturing phase and usage phase in the product’s life cycle, were selected to adopt the assessment of product carbon emission
Several factors influence the adaptation of this method could be induced from this research, that is, the data of products is easier to obtain, the information on product carbon emission could reflect the enterprise’s effort much more directly, and the performance of green supply chain management could be shown intuitively through the carbon emission reduction of products.

A grading from 1st to 3rd has been assigned to each element, whereby 3rd is high defect and therefore a greater reduction of resistance.
Other identified defects are twist, irregular shape and section reduction due to natural tapers or notches.
Other data detected during the inspections, must be considered separately.
These are humidity values, critical sections for defects and section reductions due to biotic attacks.
After the inspection steps, data were collected in graphic–descriptive tables (Fig.5).

Data Collection Field surveys conducted after the thunderstorm occurred.
Table 1 shows the data of roof failure for northern area of peninsular Malaysia from 2012 until 2015.
Table 1: Summary data recorded during field survey.
Conclusion Based on field survey data, 73 % of roof failure for non–engineered building are due to connections failure.

In order to analysis the FRFs, universal files were imported to ME’scope VES visualization modal analysis software, basic modal parameters were carried out by curve fitting function built in ME’ scope, data of the first 4 modes were extracted.
COMAC relates to the stiffness reduction at each degree of freedom.
This abnormal trend may relate to the noisy data.
The noisy data were not filtered out and it could affect the prediction of damage region.
Due to the employment of central difference operator, data at marginal points (1 and 15) could not be obtained.

These behaviors might be attributed to the length reduction of one third of P-P bonds between the adjacent NiP layers.
A few comments can be made right away: (i) As compared with the high-temperature data [Figs. 2(p)-2(r)], the hole-like band centered at X sinks below EF at 30 K [Fig. 2(m)-2(n)]; (ii) The band dispersions centered at M show a 20-30 meV shift towards higher binding energies at low temperature [Figs.2(g)-(i)] as compared to high temperature [Figs. 2(j)-2(l)]; (iii) There is one extra hole-like band centered at Г (named α) showing up at 30 K [see Fig. 2(a)-2(c)], in contrast to the data at 340 K [Fig. 2(d)-2(f)]; (iv) One additional electron-like pocket is observed around the M point at 340 K in Sr2Ni2P2 [Figs. 2(j)-2(l)] .
(Color online) SrNi2P2: (a, g, m)/(d, j, p) ARPES intensity plots of data are recorded at 30 K/340 K.
Discussion Upon cooling down below 325 K, there is an enhancement of the P-P interactions between the adjacent Ni layers in SrNi2P2 that results in a dramatic reduction of the length of one third of the P-P bonds between the NiP layers [12, 13].

This data is for the 7 x 2-inch configuration and shows data for the time period before and after a set of experiments were conducted.
Note the large variability prior to the implementation and the significant reduction when the process determined from the experiment was implemented.

The DRT as the temperature for which reduction in area is above 3% (Table 2).
Reduction in area and strength of the AZ91 alloy as a function of temperature: a) material in the as-delivered state, b) material after supersaturation and ageing (HT II) a b Fig. 4.
It has been discovered that the reduction of the Mg17Al12 precipitations with the massive morphology as a result of heat treatment increases resistance to hot cracking which is proven by NST values (Fig. 4).
The ductility recovery temperature is 370 oC in the as-delivered state, but increases to 400 oC with the reduction of the volumetric content of the Mg17Al12 massive phase and increases to 410 oC after supersaturation and ageing
