Abstract

The geometric discontinuity often causes the ‘stress raiser’ or the stress concentration (K t ). The fatigue life of a structure depends on the stress concentration, and hence it is very much required to calculate the ‘K t ’ value correctly. The calculation of exact ‘K t ’ value is cumbersome task. Here a VBA-based tool has been developed to calculate the ‘K t ’ which is well validated with other approach.
