Composite materials are central to aerospace structures, but their failure mechanisms are complex. We develop analytical and numerical models of damage in laminates and sandwich structures, and methods to detect and quantify damage from vibration and optical measurements.

Topics

• Delamination, matrix cracking and free-edge effects in laminates
• High-velocity impact on composite sandwich structures
• Vibration and buckling of beams and plates
• Damage identification with speckle shearography and modal data
