Research Profile

Composite materials are widely and increasingly used in today’s industry; for example, most advanced airplanes are largely made of composite materials. Mechanics of composite materials is concerned with the understanding and prediction of deformation, failure and properties of heterogeneous materials.  Natural biomaterials are also inherently heterogeneous. Mechanics of biomaterials is coupled with their functions; and natural biomaterials are paradigms for design of engineering materials and structures with novel properties. Many fundamental and interesting problems of composite materials and biomaterials, which are essential to the design, good performance and integrity of modern engineering structures and products, remain to be explored.
 
The research of Jianxiang Wang group is focused on the following areas:
 
(1) prediction of effective mechanical properties such as elastic constants and overall stress-strain relations of composite materials and heterogeneous materials, including nanocomposites , particle-filled composites, short fibre-reinforced composites, and continuous fibre-reinforced composites;
 
(2) prediction of effective generalized conductivities (thermal, electric, etc) of heterogeneous media;
 
(3) microstructures and mechanics of biomaterials;
 
(4) damage and failure analyses of composite materials and structures in aerospace engineering and energy technology.
