Mechanical Design, Materials & Additive Manufacturing

Mechanical Design, Materials & Additive Manufacturing is dedicated to develop multidisciplinary methods to design, evaluate, and manufacture innovative materials and technologies of wind turbine mechanical components, such as drivetrains, and metal structures. This research section combines modeling and analysis, material-level to full scale experiments, health monitoring and prognosis, and additive manufacturing to advance technology development, improve reliability, and, hence, reduce the cost of energy at both design and operation stages.
