Catastrophic failures of engineering structures and components are becoming increasingly frequent in our complex technological society. Phenomena such as metal fatigue, corrosion and hydrogen assisted cracking compromise the integrity of our infrastructure, as in the recent collapse of bridge Morandi in Genoa. Understanding how the environment degrades material performance is a challenging problem that crosses the boundaries of materials science, solid mechanics and chemistry. I will show how our scientific understanding of the multi-physics and multi-scale nature of material degradation phenomena enables predicting and preventing failures using computer models. The promising results achieved have paved the way for extending the success of Virtual Testing from the automotive and aeronautical industries to a wide range of environmentally-sensitive applications in the defence, transport and energy sectors.
