Abstract

The stress analysis of developed Al-3.7%Cu-1.4%Mg/1.5%wt Rice husk ash nanoparticles (RHAnp) composite for the production of pump impeller for industrial and agricultural applications is presented.  Impeller speed of 1050, 1250, and 1450rpm were used for the stress analysis. The Al-3.7%Cu-1.4%Mg/1.5wt% RHAnp composite indicated sufficient characteristics for successful application in the production of pump impeller. It was observed that the maximum von misses' stress obtained is far lower than the yield stress in the materials. This result imply that using these developed materials in the production of the impeller is safe, considering the judgment of the strength obtained in the work. Since the factor of safety is above one, it also indicates that failure may not occur before the exhaustion of the impeller design life.
