Principle of acoustic emission corrosion inspection The elastic wave generated from AE source propagates to material surface and it causes small surface displacements in the material which detected available by the AE sensor, and then the stress waves are converted to electrical signals by piezoelectric transducer, the signals continue to be amplified, processed, recorded and analyzed, the source location and properties can be deduced according to the results at last.
Modal acoustic emission location Conventional AE computed source location based on sensor array is affected by many factors, such as multiple wave modes, the attenuation characteristics and sensor sensitivity.
Although the accuracy of conventional computed source location is limited by wave propagation factors, it is still the most used method in engineering project; Zonal location method also get a satisfied results on occasion that are not suitable for TOA location; The new AE source location method based on the MAE technique will be widely used in corrosion detection in future.

There are mainly two types of honeycomb structuresi.e. natural and artificial honeycomb and both of these are widelyemployed in almost all field of engineering including aerospace, mechanical, mechatronics, materials and many more.
The modes of failure that could affects the honeycomb sandwich panel are facing & transverse shear failure, local crushing of core, general buckling, shear crimping, face wrinkling and intra-cell buckling also referred as dimpling [3].
Failure or damage as a result of impact consists of multitude of factors including configuration and thickness of face sheet, fabrication techniques, material geometry, interface properties between the face sheet and the core, impact velocity and energy, indenter shape, temperature, boundary conditions and environmental factors.

But, fly ash on concrete carbonation resistance and freeze resistance has undesirable affect[6].
Size effect is the mechanical properties of materials which vary with the material geometry size,and no longer a constant.
For the strength of concrete size effect people have profound understanding,but the size effects of carbonization performance is quite less, At present, many experts and scholars at home and abroad did a lot of research and experiments[8,9] on the HVFAC carbonation resistance, due to respective research direction , the factors were considered , the test purpose and the condition is different, thus in the experiments we chose the different geometry size of the briquette; consult the relatived Literature, some data in the literature[3,4,5,10,11,12] show that: under the close condition of test blocks with different Geometry size，the carbonation depth have much more difference, it is lack of obvious comparability and contact between data .
From the figure1 and figure2 can found intuitively that: with the size of the concrete test blocks increasing, the various age's carbonation depth correspondingly increase too, it is an increasing trend; In addition to the above factors, in the concrete materials ,caused for carbonation depth size effect basically has the following two main aspects: (a)The boundary layer caused the effects of the size.

Dynamic constitutive relationship of soil is the basic relationship of Dynamic mechanical characterization of soil.
Factors such as the soil texture, the confining pressure, the loading frequency, the dynamic strain amplitude, the consolidation ratio, the dry density, the initial average principal stress and others have a great influence on dynamic elastic modulus and damping ratio.
According to the research, the factors that can affect the dynamic elastic modulus and the damping ratio of the frozen soil mainly are the dynamic strain amplitude, the temperature, the loading frequency and the confining pressure。
(3) The problem is the rationality of the calculation method about dynamic elastic modulus and damping ratio, namely how to define dynamic modulus of elasticity of frozen soil correctly to reflect the elastic properties of frozen soil and the limitation of using the classical method to calculate the damping.

The F-values of the variables indicates that pH (F-value of 18.56) and adsorbent dose (F-value of 16.37) are more important factors in Pb(II) removal using RH-nZVI than the contact time This is in agreement with the findings of Wang et al [33].
The interactive effect of contact time and adsorbent dose (F-value of 15.62) is the most significant interaction affecting the amount of Pb(II) adsorbed.
The analysis of variance showed that adsorbent dose, contact time and pH, adsorbent dose and pH were the most significant variables affecting Pb(II) ions adsorption.

Many studies proved that the external bonding of FRP to soffit of the concrete beam significantly increase the mechanical performance of the structure[3].This material increases the strength at bending, reduces deflections as well as cracks width according to laboratory experiments, theoretical calculations and numerical simulation[4].
The resisting bending moment of FRP strengthened RC beam can be estimated by using load factors and safety factors as required by TR 55 guideline based on strain compatibility, internal force equilibrium and taking into account the failure mode of the strengthened beam.
A number of factors affect the magnitude of these shear and normal stress.
