| Research Abstract |
Using a friction stir processing (FSP) route, high quality porous aluminum with porosity of approximately 50 - 85% were successfully fabricated. Next, it was shown that when the mean compressive stress on a maximum-porosity cross section reaches the critical value, the plateau stress can be evaluated approximately as the nominal compressive stress. Moreover, a thin film sensor with four measurement planes, which can be applied to the compressive failure test of porous aluminum, was fabricated. A new sensor measurement system using oscillator circuit was developed and, the measurement accuracy and output stability was improved by using simple compensation factor forinternal resistance.
