Areas of Research Interests/ Research Projects

Areas of Research
Research in the field of solid and structural mechanics, has centered on the development of solution procedures for non-linear problems encountered in simulation based science and engineering. For example, the mechanism of preventing from impact wave by design new type microstructure polymer composite, dislocation mechanism based crystal plasticity theory and computation, as well as hydraulic fracture in shale, which is a complicated work coupling of multi-fracturing solids with other physical fields, involving liquids or gases.

Areas of Research Interests/ Research Projects
1. National fundamental scientific research of China (973): The Mechanism of preventing from impact wave by design new type microstructure polymer composite.
2. Key project of National Natural Science Foundation of China: Hydraulic fracture in shale, which is a complicated work coupling of multi-fracturing solids with other physical fields, involving liquids or gases.
3. Key project of National Natural Science Foundation of China: Dislocation mechanism based crystal plasticity theory and computation.

Research Status

1. The development finite element method to simulate dynamic crack propagation in gas pipelines involves both the analytical and computational study of fractured solid coupling with fluid flow to drive crack propagation and structure deformation. This work has been used to the reliability assessment for a long distance X70 and X80 steel gas pipelines from the west to east in China.
2. The fracture mechanics theory for continuum-based shell element (CB shell) is proposed and XFEM program is developed to simulate the arbitrary shape crack propagating in the curved shell. For the XFEM application, the fracture in biomaterial and composite material is modeled. These works have been summarized in the book “Extended Finite Element Method” by Elsevier, 2014, which is the second book in XFEM area in the world.
3. The three dimensional discrete-continuous computation model of crystal plasticity is developed (3D DDD-FEM). The dislocation nucleation, gliding and climbing can be simulated in the compression micro-pillars. The theoretical and numerical investigations are carried out for the single arm dislocation source controlled plastic flow in FCC micro-pillars. Atypical three-stage hardening mechanical behavior of Cu single-crystal micro-pillars is revealed, which is dominated by the dislocation starvation. Theoretical and numerical studies are also completed on confined plasticity in coated pillars, as well as mechanical annealing under low amplitude cyclic loading. The main contribution is to propose the discrete dislocation mechanism based crystal plasticity flow stress theory at micro scale to consider size effect and strain burst without strain gradient at submicron scale.
