Abstract:
The reliability of a mechanical design is established by design validation that is
carried out using finite element method. Such a numerical technique method provides a very
useful alternative to experimental testing which can be very expensive. During FE analysis,
the overestimated stress concentrations need to be resolved or in some cases eliminated, in
order to predict the actual response of the material. This thesis is aimed at developing a new
and improved method for resolving and eliminating overestimated stress concentrations from
an FE model. The proposed method is validated using an appropriate geometry whose
experimental results are available. This will result in a provision aimed at better mechanical
design methodology for application on any finite element static analysis.
