Lithiation-Driven Fracture of crystalline silicon

Using phase-field fracture and classical phase-field method to track phase change we modeled lithiation-driven plastic swelling and fracture of silicon crystalline nanopillars.   

 

Elasticity

Using phase-field fracture (variational approach to fracture mechanics) and my parallel FE code, there is a wide range of fracture mechanics problems that can be solved. 

Fracture of modified ASTM E1820

Fracture of double hole double notched sample

Brittle matrix fracture and debonding around a fiber

Bronkenshire Fracture Test

VFMFD

The following are some examples of my FD code that show the complex interaction of interlayer debonding and channel fracture in the film.
