The strength of nodule-decorated whiskers

In this work, the strength of whisker containing nodules was studied. The relationship between the nodule geometry and the strength of the whisker is reported. The optimum ratios of the nodule radius to the whisker radius and the distance between two nodules to the whisker radius are presented. An increase in the nodule radius can increase the strength of the whisker-reinforced composite. Theoretical calculations indicate that, when the radius ratio of the nodule to the whisker is 2 and when the ratio of the distance between two nodules to the whisker radius is in the range of 2 to 2.5, whisker strength reaches an optimum value. The selection of the ratios is affected by a number of factors, such as the ratio of the distance between two nodules to the whisker radius and the stress distribution in the whisker and the nodule. This study provides practical design values for the fabrication of whiskers.
