A WARM MODE OF GAS ACCRETION ON FORMING GALAXIES [PDF]
We present results from high--resolution cosmological hydrodynamical simulations of a Milky--Way-sized halo, aimed at studying the effect of feedback on the nature of gas accretion. Simulations include a model of inter-stellar medium and star formation, in which SN explosions provide effective thermal feedback. We distinguish between gas accretion onto

Warm Electromagnetic Forming of AZ31B Magnesium Alloy Sheet [PDF]
Historically, electromagnetic forming technology has mainly been used to form parts from aluminium and copper alloys due to their excellent electrical conductivity and limited formability by conventional methods. However, little research has been carried out in high strain rate forming of magnesium alloy sheets.

Modelling of aluminium sheet material at elevated temperatures [PDF]
The formability of Al–Mg sheet can be improved considerably, by increasing the temperature.\ud At elevated temperatures, the mechanical response of the material becomes strain rate dependent.

Development of Warm Punch Using Friction Heat
In press forming, most forming is performed cold. However, warm or hot forming is used for hard materials. In the present study, we focused on the heat generated by friction between metals and worked on the development of the warm punch that utilizes ...

In-Line Dimensional Inspection of Warm-Die Forged Revolution Workpieces Using 3D Mesh Reconstruction
Industrial dimensional assessment presents instances in which early control is exerted among “warm” (approx. 600 ∘C) pieces. Early control saves resources, as defective processes are timely stopped and corrected.

Warm forming simulation of Al–Mg sheet
The accuracy of warm forming simulations depends to a large extend on the description of the yield surface with temperature and strain-rate dependent hardening and on the modeling of friction. In this paper, the anisotropic behavior of the sheet is described by using the Vegter yield locus, which is purely based on experimental measurements.
