Abstract
The effect of geometry on elastic stress concentration factors for hollow tubes with internal projections subjected to axial loading has previously been investigated by the present authors. In this paper, some previous results are used to obtain equivalent prediction equations using a statistical multiple linear regression model. The accuracy of this model is measured using a ‘multiple coefficient of determination’, R2, where 0 < R2 < 1. This coefficient is found to be greater than or equal to 0.94 for all the cases considered in this study (0.96 in most cases), demonstrating the quality of the model fit to the data.
