Abstract

Two case studies are presented which employ the experimental technique of thermoelastic stress analysis in order to verify finite element models of components from an off-road bicycle. The design of the finite element simulations is detailed and selection of elements and loading conditions justified. The use of a thermoelastic detector with a focal plane array allows full-field maps of surface stress to be determined, which are subsequently used in an evaluation of the finite element simulations. Good agreement is shown between the simulations and the experimental data, and the paper concludes that this current generation of thermoelastic detectors provides a valuable method of validation for complex finite element models.
