Many studies on necking show that, when the stretch-rate governs plastic flow behaviors, the strain-rate, inertia and material properties may cause the necking retardation [1, 2].
The strain rate sensitivity, strain hardening and thermal softening, inertia and heat conduction [8-10] affect the formation of shear bands.
This work proposes a universal criterion and studies the influences of material mechanical behaviors and loading conditions on the stability of plastic deformation with phase diagram.
The effects of strain rates, strain rate sensitivity R0 and heat conductivity l on thermal softening depend on the proportion factors hij.
The heat affecting zone fills up the full testing segment and extends outside the testing segment by heat conduction.

Stress and Strain Analysis of Asphalt Pavement Impacted by Temperature and Load Jian Li1,a 1Research Institute of Highway Ministry of Transport, Beijing, China, 100088 a jian.li@rioh.cn Keywords: Asphalt Pavement; Temperature; Load; Coupling Effect; Stress and Strain Abstract:emperature and load are the major factors of road surface deformation.
The influence of coupling effect of temperature and load is more significant than a single temperature or load factor.
The material properties of asphalt concrete is complicated, and its mechanical properties is depended on temperature and load.
Effect of load on the asphalt pavement Load is another important factor leading to the asphalt pavement rutting.
Within the calculated temperature range, the max increment of compressive stress spots at 12cm beneath the surface, which means the compressive stress of up-base is more affected by temperature changes.

The underlying factors for a stable buildup are local heat transfer, powder catchment efficiency, surface shape, roughness, and oxide layers.
However, martensitic steel is gaining more and more importance in turbo machinery parts due to its outstanding mechanical properties [6].
The lower the geometric factor κ, the lower the applied laser power.
According to the Hall-Petch rule [11], a homogenous microstructure indicates homogenous mechanical properties and a finer microstructure would lead to higher hardness.
This leads to the assumption that the martensite formation that mainly affects the hardness is mostly driven by the local heat flow during the solidification of the a melt pool and less by the global heat flow and geometry.

The optimum set of factors (mass of the shot, volume of the chamber and strip-sonotrode distance) that maximise the Almen intensity was found.
The changes in surface layer properties were characterised using roughness, microhardness and residual stress measurements.
Table 1 summarises the studied factors on TiAl alloy with two different experimental levels.
The resulting factors observed are the residual stress profile (maximum stress, depth of the maximum stress, depth affected by shot peening), roughness and microhardness.

PVDF has good piezoelectric properties and has excellent mechanical strength while retaining flexibility.
The physical and piezoelectric properties of the energy harvester are outlined in Table 1.
The area around the damage location was found to be severely affected, as was expected at the beginning of the investigation.
This proved to be a factor of the order of 0.06.
As can be seen in the figure, all other regions had a factor of between 1.16 and 0.93.

Simulation Investigation for Heat Transfer in Fin-tube Thermal Storage Unit with Phase Change Material Jianyou Long Department of Mechanical and Electronic Engineering, Shunde Polytechnic College, Foshan Guangdong528333, P R China jianyoulong@163.com Keywords: fin-tube; phase change; heat transfer; simulation Abstract：This paper addresses a simulation investigation of a fin-tube thermal storage unit involving phase change process dominated by heat conduction.
Because its heat transfer performance is affected by many factors, such as thermal properties of PCM and geometrical sizes of fin-tube thermal storage unit, it is so complicated that it is difficult to calculate or simulate its heat transfer process.
Following simulation aims to show that how the inlet water temperature affects heat release process when the fin distance is 12fin/inch.
This is because outlet water temperature is decided by inlet water temperature and temperature increasing in thermal storage unit (Outlet=Tinlet+△T), and thermal resistance, which affects temperature increasing greatly, gradually dominated with time increasing.

Liquid metal embrittlement is caused by a combination of two factors [2].
These are 1) The presence of a specific liquid (molten)metal in contact with the affected component or structure, and 2) An applied or residual tensile stress acting on the affected component or structure while in contact with the liquid metal.
The hardness and deformation behavior of the solid metal affect its susceptibility to LME.

Luminescence Properties of HgI2 under the HAUT.
It is impossible to find out which mechanisms control the acoustic properties of crystals without additional experiments.
Thus, one can try to find out if there exists any influence of HAUT on other properties of crystal.
Such a complex behavior of hδ and ( )hEE � , as well as of ( )iEE � under the action of light and HAUT can be due to a number of factors.
