Pressure distribution in a large-anvil pressure cell

Journal of Alloys and Compounds, 2004
Minimising the pressure gradients in large-anvil pressure cells is one of conditions for getting the high-quality results in investigations of structural and physical properties of the solid state. Pressure or temperature distributions in such devices are usually studied by scanning the sample with finely collimated X-ray beam.

Seat pressure distribution.

Collegium antropologicum, 1998
The field of seat pressure distribution has grown more and more important in the last five decades. Compared to the early phases of development, when only a description in principle was the goal, the quantitative differentiation of force induction and furthermore the evaluation of different supporting systems by these methods have gained importance ...
