Nonlinear Interfacial Mechanics

  Interfaces are critical factors influencing load transfer and deformation failure, characterized by universality, complexity, and low dimensionality. Studies on interfacial mechanics often involve complex mechanical interactions such as contact, constraints, and instability, encompassing a wealth of scientific questions and mechanical challenges. Our research group focuses on nonlinear interfacial mechanics and has conducted innovative research in the mechanics of "soft interfaces" in biomembranes and shells, as well as the mechanics of "hard interfaces" in nanostructured metallic materials.

Nonlinear Mechanics of Soft Interfaces

    Biological membranes, a quintessential class of soft interfaces, exhibit intricate mechanical interactions with their external environment. Precisely quantifying their nonlinear large deformation and interactions with nanomaterials is essential for understanding and regulating key cellular processes, including cell shape modulation and endocytosis.

Interfacial Mechanics of Nanostructured Metallic Materials

    Multiscale interfacial structures, including grain boundaries and shear bands, interact strongly, playing an essential role in shaping mechanical properties of nanostructured metallic materials and their fabricated components.
