Research

Dr. Qu’s research interest crosses several areas including micromechanics of composites, interfacial fracture and adhesion, fatigue and creep damage in metallic and polymer materials, fuel cells and batteries, thermomechanical reliability of microelectronic packaging, and ultrasonic nondestructive evaluation of advanced engineering materials.
His discovery of a reciprocity relation between the reflection and transmission coefficients at anisotropic bimaterial interfaces has led to the development of several ultrasonic techniques for nondestructive evaluation of composite laminates. He is a recognized expert in interfacial fracture mechanics. His solution to the Eshelby inclusion problem with imperfect interfaces provided a building block for developing micromechanics solutions of the effective properties of composites with imperfect interfaces.
