The factors causing an excessive production of water or high water cut level in oilfield are channeling behind the casing, coning effect, rise of oil-water contact and breakthrough of injected water [2,3].
Thus, polymer gel system that possess good properties of water shutoff gel such as controllable gelation time is favourable.
Gelation time was recorded when the gel reaches H code which describes a slightly deformable non-flowing gel properties.

Fatigue problems about large sized structure components ,such as bridge crane girder , has always been the bottleneck of mechanical products lightweight, reliability, security.
Fatigue failure mechanism is very complex about bridge crane for a long period of alternating loads, because a lot of factors that affect the fatigue behavior[1,2,3].
The actual processing of welding influencing factors were ignored in the above analysis, then the local details of welded joint fatigue problem will be analyze the fatigue properties focus on the most dangerous position.
Fig5 Dangerous position in mid-span section Fig6 Dangerous position in 3D model Combined with welding process technology characteristics of their own technology to retain the weld heat affected zone and the consistency of the welding process and the process parameters of the actual bridge crane, characterized in figure 7 shows, determine the welded joints simplifying principles are as follows: a.

Homogenization methods are powerful tools helping the engineer towards the design and calculation of homogeneous mechanical, thermal expansion, conductivity and other properties considering the micro-structure response of each constituent.
RVEs for the studied cases from left to right: Isotropic, Transversely isotropic, Orthotropic The microstructure properties is an epoxy matrix material with E = 5500 Mpa , v = 0.395 and glass spherical inclusions with properties E = 73100 Mpa and v = 0.18 and volume fraction of inclusions 0.238.
For this specific model which is a 2d plain strain model the mode 3 fracture is not considered since it is the fracture due to out of plane shear, and only two intensity factors are calculated.
It is worth mentioning that for uniaxial tension the contribution of the stress intensity factors other than KI can be ignored.
The crack path is predefined and from the fracture mechanics model the stress intensity factors are calculated at the crack tips.

Introduction Fatigue failures commonly take place in engineering structures and mechanical machines, and will lead to fatal accidents.

The parametric study reveals that the load-carrying capacity is influenced by many factors including the rise-to-span ratio, slenderness ratio, loading cases and material properties.
In this study, the NL_Beam3D developed by Wu (2007) [5] is adopted to simulate the mechanical response of the CFST-CSW arch.
Apart from S/C ratio, grade of the in-filled concrete also affect the strength of the cross section.
It can be noted that slenderness of the arch is also an important factor for ultimate load.
But in practice, it should be determined by considering the economic factors.

However, the literature studies have shown [2 – 24] that a wide range of DBM can be produced on the basis of magnesia binder (plasters, mortars, paint formulations, primer and putty, mixtures for floors, etc.) with improved physical-mechanical and performance properties.

This solution prevents the formation of condensation inside the wall, and resists cold and other unfavourable factors inside the premises.

It is found that the microstructure including hard phases and binder in the sintered composites has a strong influence on technological properties.
The microstructure of cladding was considered as a key factor affecting wear resistance and life of the bonded component.
The quenching and temper were considered as effective methods to improve the mechanical properties of the cladding.

In this paper, a test specimen design was determined which is well suited for testing the material properties transverse to the fiber direction by calculating the influence of geometric details of shoulder bar specimens with the help of finite element simulation.
Since the stress concentrations in the shoulder and in the clamping relax relatively quickly, a shorter test area than in reality does not affect the results as long as the areas of stress concentrations do not overlap. [3].
The influencing factors which have been simulated are shoulder geometry, width of the clamping, influence of the tab, tab-offset and influences of the adhesive layer.
Mechanical Testing Regarding the results from simulation, two different proposals for a specimen design were developed and the tab-offset with the best simulation results was chosen.
