Preface

This volume contains some of the contributions presented at the 2nd Workshop on
Corrosion Modeling for Life Prediction (CMLP 2010), Rome, Italy, 18 to 20 April
2010, held under the auspices of the Office of Naval Research Global and the
Università degli Studi di Milano.

In organizing the workshop every effort was made to invite corrosionists working in
the field of lightweight alloys and dealing with modelling. Their expertise provided a
base to discuss corrosion problems and solutions for Military and Aerospace Systems
and Facilities, thus laying the foundations for tackling still unsolved issues.

The use of lightweight metals and composites to replace heavy structural materials for
military hardware and weapon systems (ships, aircraft, ground vehicles, etc.) is a new
strategic requirement for defence forces, falling under Naval S&T Strategic Plans.
Objectives of the workshop were to seek the state of the art outside the continental
United States in the field of low density metallic materials and composites for
structural applications, as well as in modeling and simulation software tools capable
of generating and identifying damage evolution data for health monitoring, corrosion
control, life prediction and assessment of civil and military hardware systems.

We would like to use this opportunity to gratefully acknowledge the invaluable
contribution, to make the Workshop a success, of all those participating in this
venture, from the organizers to supporting institutions and companies, to speakers and
attendees, as well as to the hotel staff, despite the volcanic eruption occurred in Island
in the very days of this event.
