Twin Roll

In twin-roll strip casting process, the temperature variation of casting roll can result in roll thermal stress and fatigue. It not only affects the thermal deformation of casting roll and the generation of the roll surface cracks significantly, but also influences the surface quality, shape and profile of the produced strip, and the service life of the casting roll. In this paper, a 3D coupling thermal-flow finite element modelling has been conducted. For twin-roll casting of stainless steel, the influences of the casting speed and liquid level in molten pool on the temperature field of casting roll have been simulated and discussed. The developed model is very helpful in optimising the processing parameters and the design of casting roll during twin-roll thin strip casting.

The deformation of an injection-molded part of a motorcycle seat support during the free-cooling stage after ejection was studied by an experimental and numerical method. Numerical analysis of heat transfer based on the uneven temperature distribution measured in the seat support was employed to re-construct the initial temperature field of the part. The temperature field was then introduced into the FEM codes to calculate the deformation of the ejected part due to thermal-stress during the free-cooling stage. It was found that the high and uneven temperature distribution of the part leads to an uneven shrinkage during cooling after ejection, which is primarily responsible for the warpage of the part.

According to the researches of fire resistant experiments, based on the previous authors works, a numerical analysis of the effect of restraint on the fire resistance of concrete structures is done. The relevant effects include temperature field, saturation, vapor pressure, mechanical damage and thermal stress of structure etc. In particular, we focused on the thermo-hygro-mechanical detailed behaviors of concrete that can not be obtained from laboratory experiments, which will provide important reference for the fire resistance design of concrete structures.
