Research Areas

Current research interests include the following areas:

Composite Materials and Structures – Advanced fiber composites have gained wide applications in aircraft and aerospace structures. Our research programs cover a broad spectrum in mechanics and design of various composite materials and structures. Research topics include developing methods for testing and modeling high strain rate and fracture behavior of polymeric composites, unconventional modeling of heterogeneous solids, exploring the use of nano particles in reinforcing composites, developing self-assembly methods for processing nanocomposites, improving methods for joining composite structures using adhesives, and developing multifunctional composite materials and structures.

Fractures Mechanics – Fracture mechanics is an important tool in analyzing failure in materials and structures. Our current research focuses on (1) the inadequacy of LEFM in brittle fracture due to the small size of K-dominance zone that renders stress intensity factor alone to be incapable of characterizing fracture toughness; and (2) the physical foundation of cohesive zone modeling of fracture with the attention centered on the cohesive traction law: its physical meaning and conditions it must satisfy.

Nanomaterials – Many nanostructured materials possess highly desired physical and mechanical properties and offer tremendous potentials in many applications. Our research is concentrated on developing multiscale modeling techniques for nanomaterials and their composites and on the use of molecular mechanics to study the mechanical behavior of nanomaterials including nancomposites.

Acoustic Metamaterials – Acoustic metamaterials are materials with man-made microstructures that exhibit unusual mechanical properties such as negative effective modulus or negative mass density that is not found in natural materials. Many of the recently developed metamaterials are in the form of composites. If modeled as a homogeneous classical elastic solid, the effective mass density of a metamaterial would have the form of a second order tensor and is frequency-dependent. Moreover, the microstructure can be designed so that the representative homogenous elastic solid would possess an anisotropic mass density and may become negative in certain frequency range. This unusual property may be used to tailor the wave motion and produce an anisotropic band gap structure of the metamaterial. Many novel applications can be realized using the anisotropy and negativity of the mass density of this metamaterial. Potential applications of acoustic metamaterials are still being explored.
