Research areas description
The Canada Research Chair in Multiscale Modelling of Advanced Aerospace Materials models advanced aerospace materials and processes to predict their long-term performance. Its research efforts will lead to accurate and efficient computer models to predict the mechanical response of materials and processes used in the aerospace industry
Aerospace innovations are driven by the use of lighter and more resistant materials. One innovation that is increasingly being used in civil aircraft is lighter-than-metal composite materials. Another is shot peening—a process that modifies the mechanical properties of metals, which can extend the lives of some metallic parts by 20 times. However, the Canadian aerospace industry lacks the scientific and technical skills to fully integrate these advanced materials in the design process.
Materials failure and damage mechanisms are immensely complex phenomena. Defects at the atomic scale can lead to small cracks, which can develop into larger cracks and ultimately lead to catastrophic failure. As the service life of materials is driven by a broad spectrum of factors that can occur over time, a number of approaches must be developed to take all of them into account.
Dr. Martin Lévesque, Canada Research Chair in Multiscale Modelling of Advanced Aerospace Materials, is developing and testing new models to evaluate the mechanical response of advanced materials used in the aerospace industry. Lévesque is focusing his efforts on predicting the long-term response of composites in service conditions. He is also predicting the effects of shot peening on metal fatigue and developing cost-effective and innovative procedures to test materials under complex load and environmental conditions.
The models Lévesque develops will allow the Canadian aerospace industry to design lighter and safer aircraft parts that will consume less fuel and require less energy to be manufactured, thus decreasing the environmental footprint of air travel.
