Solid Mechanics Program

The field of solid mechanics bridges research in materials science and structural mechanics and design. The Office of Naval Research Solid Mechanics program supports research in mechanics of deformation, damage evolution and failure of composite hull structural materials in the naval environment, when subjected to complex three-dimensional static, cyclic and dynamic loading conditions. The program aims to establish physically based models for material behavior, with predictive capabilities. The current focus is on marine composites and sandwich structures.

Areas of Interest

  • 3D failure modes, mode coupling and failure criteria
  • Effects of moisture, sea water, hydrostatic pressure and temperature
  • Durability and life prediction
  • Effects of dynamic loading (e.g. impact, shock, blast implosion)
  • Mechanics of nanocomposites and multifunctional composites
  • Concepts for mitigation of damage and failure, and life extension
  • Concepts for the enhancement of thermo-mechanical properties and structural performance
  • Materials systems of interest include composites and sandwich structures for naval ship hulls.
