Introduction The recent development of high power laser makes the laser welding more powerful, flexible and convenient in the transportation industry, instead of spot welding. [1,2,3] Although laser welding has many potential advantages such as low heat input and high aspect ratio of weld bead, its application to a new structural component still requires a lot of engineering data including mechanical properties such as tensile strength, fatigue strength, etc.
To understand the fatigue test results, the effects of local stresses around a weld bead were calculated by FEM and the magnification factors were introduced on the expression of local stresses around a weld bead by theoretical stress analysis.
The magnification factors were not suggested as functions of geometric features, but calculated as a constant for the geometry of the specimen from the FEM results in this paper.
The magnification factors were mainly due to the eccentric coupling moment.
The derived stresses are listed below, xσ and yσ are expressed in terms of ∞σ and magnification factors, which are non-dimensional functions of thickness, gap size, bead width.

It is important to underline that if the crack growth rate was measured within blocks of impacts (open circles in Fig. 5) an additional increase in the crack propagation rate by a significant factor (close to 6) is observed.
The IF blocks within the loading history also affect the uniformity of the fracture surfaces of adhesively bonded joints, as illustrated in Fig. 6.
Material properties were obtained from previous work [6, 8].
The LSJ is also suitable for this purpose but caution should be paid to changing mode mixity and multi-mechanism fracture path as the crack propagates in this test since these factors will affect the crack growth rate.

In turn, these inter-storey vertical bands are connected to the continuous horizontal masonry bands running at each floor levels: horizontal arches within the latter allow the transmission of the seismic forces affecting the inactive walls to the perpendicular active walls.
Vertical loading patterns varying the point of application of the self-weight of the piers: a) top section of the pier, b) center of gravity of the pier The seismic action is modelled with a system of horizontal forces affected by an increasing load multiplier l.
Regarding the mechanical properties of the involved materials, the specific weight and the compressive strength of the masonry material are taken to be equal to 16 kN/m3 and 2 MPa, while the yield stress of the steel ties has been set equal to 240 MPa.

Automobile,as a big consumer of energy ,has been borne aloft .Requirement of automobile ont only seek for property and comfort,but also make demand of energy consumption and environmental protection.
As for the fuel cell vehicle, there are many technical problems to be solved in the technical level.the development may also be affected by certain obstacles.
On the other hand, as a new type of car, Its repair and maintenance costs are higher, And the repairs and maintenance site is lacking at present, These factors obstruct consumers to purchase the new energy automotive, ● in the integration of resources terms, China's new energy automobile development research mostly fight the enemy separately, enterprises have no contact and communication, Industry Association is not to act as a broker, Lead to many enterprises have to do something that other people have done, this action is time-consuming and wasted resources seriously. therefore, how to motivate effectively market resources allocation function, allocate reasonably new energy vehicle market resources and production factors, is a important task we have to face.
The quantity must be accurate, to ensure the engine output power, sufficient burning of fuel, and reduce exhaust emissions, Realization process also needs sensor to monitor factors affect ignition, feedback regulation, so as to achieve the optimum ignition timing
