| Abstract: | The design philosophy and the performance of a self made pressure sensor are presented. With the sensor, pressure distribution in the mould during the compaction process is determined, from loading to unloading, by burying the sensor in powdered materials. The effect of pressure distribution of powdered material mould by pressure in compaction on residual stress distribution after the process is studied. |

| Keywords: | strain transducers residual stress powder compacting |
