A three‐dimensional hybrid finite element — spectral boundary integral method for modeling earthquakes in complex unbounded domains (2021)
Journal Article

We present a 3D hybrid method which combines the finite element method (FEM) and the spectral boundary integral method (SBIM) to model nonlinear problems in unbounded domains. The flexibility of FEM is used to model the complex, heterogeneous, and no...

UGUCA: A spectral-boundary-integral method for modeling fracture and friction (2021)
Journal Article

Uguca is a C++ parallel implementation of the spectral-boundary-integral method to model the dynamic failure of interfaces between two elastic half-spaces. Due to its computational efficiency, uguca is suitable for fundamental research on dynamic fra... Read More about UGUCA: A spectral-boundary-integral method for modeling fracture and friction.

Effective Toughness of Heterogeneous Materials with Rate-Dependent Fracture Energy (2021)
Journal Article

We investigate the dynamic fracture of heterogeneous materials experimentally by measuring displacement fields as a rupture propagates through a periodic array of obstacles of controlled fracture energy. Our measurements demonstrate the applicability... Read More about Effective Toughness of Heterogeneous Materials with Rate-Dependent Fracture Energy.

Nucleation of frictional sliding by coalescence of microslip (2021)
Journal Article

The onset of frictional motion is mediated by the dynamic propagation of a rupture front, analogous to a shear crack. The rupture front nucleates quasi-statically in a localized region of the frictional interface and slowly increases in size. When it...
