This research improves the reliability of metal 3D-printed parts by studying internal porosity using X-ray computed tomography and extreme value statistics. By modeling the largest, failure-critical pores and accounting for uncertainty and geometry effects, it enables better prediction of fatigue performance in aerospace and medical components.

This research redesigns long wind-turbine blades for low-wind-speed sites by shifting structural strength from the internal spar to the aerodynamic shell. The new “eggshell-like” design reduces bending under the blade’s own weight, requires less material, and lowers costs—helping make wind power cheaper than fossil fuels without relying on political action.
