Therefore, in terms of the durability design of structures of buildings in coastal area, the study on the mechanical properties of the structure under short-term corrosive effect has practical significance which can not be ignored.
In this paper the mechanical properties of reinforced concrete beams are studied; the changes of the cracking load and carrying capacity of the components with prolonged corrosion in normal use are elaborated and with the mathematical model of the cracking load an indepth mechanism analysis is made on the result of the test.
Test Results and Analysis on Mechanical Properties of Beams in Bending Distribution and development of cracks The cracks' emergence and development of the beams are different.
Thus it can be seen: the effect of the additional expansion prestress to the cracking load , ultimate load and other mechanical properties of the beams which are corroded by salt fog can not be neglected.
This paper introduces the concept of the additional expansion prestress and establishes a mathematical model of the additional expansion prestress based on which the computational model of the cracking load is deduced, and combine with test data, proves that the important role the additional expansion prestress plays on the mechanical properties of members being corroded.

Various factors have to be considered when assessing the feasibility of welding dissimilar metals and producing a sound weld joint.
This paper presents a broad classification of the most commonly used welding processes for dissimilar materials, discusses some of the commonly used welding processes with examples of some common material combinations, critical factors for good welding, and practical difficulties arising from the physical and chemical properties of materials.
Sound joints with good mechanical properties, however, are difficult to achieve by those conventional welding processes which form brittle Fe-Al intermetallic compound (IMC) layer at the interface of a steel/aluminum weld [8].
However, the properties are suitable for use in most normal applications [14].
The main factors that influence the properties of dissimilar welded joints and any variations in these factors that may lead to failure (cracking) are discussed below: Weld Metal.

The simulated behavior of passenger impact can predict useful information for experimental validation of floor properties.
Progress of the fall depends on many factors.
Therefore the mechanical properties of individual parts of floor must be measured.
This knowledge of the behavior of the floor will greatly affect proposal validation experiment and tests of mechanical properties.

Introduction Nanostructured SnO2 in the form of wires, tubes, belts with high aspect ratio offer unique surface properties.
The properties of SnO2 nanoparticles ulitized in modern nanodevices may depend on its morphology[2].
With precise growth control, the morphology and aspect ratio of SnO2 properties stated above can be tailored.
Understanding factor effects leads to adjustment of these factors to optimize the process output [7].

Two main factors effecting reducing yield were determined, namely: heating system and briquetting.
Based on the thermodynamic calculations and analysis of the reduction reaction process, the major limiting factors of affecting direct reducing yield are determined and the conditions of high yield are finally established.
The relevant references [4, 5] have studied on the levels of these factors but the yield is still not high.
(2) The main factor affecting the yield of metal Sm is heating system.

And its mechanical properties are not consistent.
Moreover, there are weld defects, stress concentration, the microstructure and mechanical properties change as well as residual stress in welded joint [4-6].

It is also shown that the physically coating processes will not significantly affect the mechanical properties of the fibers and yarns.
In fact the lower density usually lead to a higher add-on, therefore, the add-on is one of the most important factors which will affect the conductivity.
(a) PP filament yarn; (b) 100% cotton spun yarn Fig. 6 Conductivity of PVA /CBs coated yarn at different CB weight portion Discussion Effect of coating on mechanical properties of the yarns It is desired that conductive yarns after coating can retain the most of strength, stiffness and flexibility while gaining good conductivity.
The retainability of textile properties is very important because the conductive yarn would be transformed into textile structures by weaving, knitting or other manufacturing processes in smart textiles or other applications.
Fig. 7, as an example, shows the tensile behavior of the yarn was not significantly affected by the coating processes.

Nb stabilized austenitic stainless steel, Type 347 has been widely used as surge line piping of current light water reactors for their excellent corrosion resistance, good fabricability and adequate high temperature mechanical properties [2].
However, it has been observed that a large degree of heat-to-heat variability in mechanical properties of the Type 347 stainless steels.
However, the systematic investigations to a relationship between the alloying elements and the fracture properties of the Type 347 stainless steels were scarce.
To obtain a deeper understanding of the micro- structual factors affecting fracture Fig. 3.
Therefore, it is concluded that the Type 347 containing 0.023 wt% C and 0.071 wt% N had a optimum properties for applying LBB design to nuclear piping.

Results had shown that the properties of recycled concrete waste aggregate are weaker than natural aggregate [3].

HSTRs could bear high temperature of 600-1200℃ and complex stress styles, and at this temperature keep good mechanical property for a long time.
Those factors above collectively caused that when tool passed the cutting area, chip broke away from woekpiece processing area immediately (Fig. 6).
Cutting temperature is a key factor that affects tool wear, tool life and workpiece surface texture, because both tool and workpiece materials weakened in high temperature.
There are plenty of factors affecting it, such as tool geometry, tool material, cutting data (cutting speed v, feed f and cutting depth aP) and so on.
Cutting force, heat and vibration were main factors.
