To produce high quality steel strips with desired mechanical properties, the Thermo-Mechanically Controlled Process (TMCP) must be managed.
The main benefit of the virtual rolling model is comprehensive simulation of the evolution of thermal, metallurgical and mechanical phenomena which increase understanding of the combined effect they have into the thermo-mechanical properties of steel strip.
Microstructure Module Understanding metallurgical phenomena in a steel strip during hot rolling is essential to understand the thermo-mechanical properties on a deep level, as well as to predict final product properties.
The idea of this equation is that when recrystallization progresses, the material mechanical properties revert to the undeformed state.
The main idea is to consider all boundary conditions affecting the steel strip in a hot strip rolling process.

A scaffold was produced using the HA suspension produced at room temperature, but further understanding of the suspension properties and the optimum conditions for coating of the PU foam are required for improved mechanical performance.
Various factors can be considered in the optimisation of this reticulated foam technique and the properties of the ceramic suspension are fundamental.
Reaction temperature has been shown to have an effect on particle morphology [11-13] and this particle morphology affects the suspension properties and subsequently may effect the coating ability.
This high aspect ratio was associated with significantly more agglomeration, likely to be detrimental to the suspension properties.
• HA scaffolds have been produced showing good replication of the PU foam structure but clearly, further understanding of the suspension properties and the optimum conditions for coating of the PU foam are required for improved mechanical performance.

The residual stress significantly affects the fracture behavior of the pipe.
The pipe with bending work has effects on the piping properties due to changes in shape and residual stress, so the properties of the pipe with bending work will have big difference with base material.
The properties of materials such as yield strength, tensile strength of pipe used in this study were obtained from studies by Kim and others, and the results are as Table 1.
The properties of copper piping used for the finite element analysis are the general copper with the elastic modulus 125Gpa and Poisson’s ratio 0.33.
The properties of elastic area used in analysis used properties of general copper, and as data of plastic area, acquired true stress-true strain curve was used from the studies by Kim and others [3].

Consequently, it is urgent to measure basic mechanical properties of the material and develop a comprehensive constitutive model for reliability and failure analysis.
As a dominative micro-defect in the rupture process of ductile metal, Voids can reduce electrical and thermal conductivity of the joints, degrade the mechanical properties and even induce crack initiation and propagation [9, 10].
The factors that affect voids formation and coalescence are complex and voids will evolution under thermal, mechanical or electrical load.

Introduction To realize significant cost-saving, increasing of operating pressure and deterioration of serving circumstance[1], properties of strength, toughness, weldability, anti corrosion, anti-HIC and anti-SCC for pipeline steel are more strictly required.
Pipeline steel properties are controlled fundamentally by the chemical composition and the cleaness, especially the content of non-metallic inclusions.
Inclusions are one of the dominant factors affecting HIC which are usually considered as irreversible trap sites in steel [9].
Inclusions, especially the large scale inclusions are the most harmful to mechanical, anti-HIC, anti-SCC and other properties for pipeline steel.
To avoid the influence of inclusions on the properties of pipeline steel and mis-down grade induced by mold entrapment during the period of drastic changing of casting speed, the increasing rate of the casting speed approaching to stead casting state should be adjusted more evenly.

Introduction Increasing global attention has been given to the reduction of dredged sludge volume before its disposal or reuse[1].The significant factor of sludge handling system is the dewatering operation.
More clay composition and higher water retention performance increase the difficulty of dehydration.Understanding the factors that influence sludge dewaterability is crucial for the effective improvement of sludge dewaterability[2].

Surface properties were also analysed.
However, there is no direct correlation between these two factors as far as the other samples are concerned.
Moreover, cell proliferation on biomaterials also depends on other factors as titanium structures formed [26] and surface properties such as roughness or surface charge [27].

Tunnel surrounding rock under high stress based on the actual engineering background, model test process of excavation in soft rock tunnels under the distribution factors was finished in triaxial test mechine.
When weak surrounding rock geological structure is appeared in practical engineering, the randomness of spatial distribution of mudstone interlayer thickness and the mechanical strength low could cause the construction weaken and affect the instability of long term stability.
Deformation and buckling of engineering are not instantaneous, and have the obvious creep property.
Soft rock thickness influence the stress curve Various factors were taken into consideration during the test, it could be seen that the stress of each measuring point changing with the excavation progress forward.
Through the small scale model test of cavern excavation the sensitive factors of stability, there are initial stress field in rock mass before the cavern excavation.
