Group of Impact Dynamics and Coupling Effects

Our lab addresses a variety of topics in the general area of mechanics of materials and structures coupled with its working or processing environments, which include the interaction between the structure and fluid, the interaction between the structure and thermal field, and the interaction between the materials and shock loading. The overarching goal is the solution of technological problems through the integration of analytical, computational and experimental techniques. Depending on the specific problem at hand, we study and apply concepts and methods of solid mechanics, fluid mechanics, heat transfer and materials sciences.

  New Progresses

Hydrodynamics & Fluid-Structure Coupling area, which orients to analysis and solve the problems of mechanics of fluid-structure coupling system in the applications of the national key engineering projects, seeks to clarify the mechanisms, provide the design guideline and guarantee the safety in fluid-structure coupling systems in practical engineering. The main researches are mainly including:
    •     Unsteadycavitating flow mechanism
    •     Mechanism and dynamic loadings of collapse of cavitation bubbles around the high-speed underwater vehicle in the out-of-water process
    •     Fluid-structurecoupling of high-speed vehicle during underwater launching process
    •     Maneuverability of new pattern vehicles in the underwater and surface navigation conditions
    •     Fluid-structure coupling of the large-scale flexible airship.


This platform dedicates to the research of some transient energy transformation process (high-speed deformation of material, laser shock peening and explosive underwater etc.). The high density laser is used as the driven sources which can generated a very high amplitude (up to 5 GPa) pressure pulses in very short time (about 20 ns). A variety of high spatial and temporal resolution test method including PVDF (Polyvinylidene Fluoride), PDV (Photonic Doppler Velocimetry) and high-speed camera etc is adopted to capture the transient process. The main experimental system includes:
•  Laser shock peening system
•  Dynamic material property system
•  Underwater explosive system
