Propagation of extended fractures by local nucleation and rapid transverse expansion of crack-front distortion (2024)
Journal Article

Fractures are ubiquitous and can lead to the catastrophic material failure of materials. Although fracturing in a two-dimensional plane is well understood, all fractures are extended in and propagate through three-dimensional space. Moreover, their b...

Energy-absorbing particles for enhanced mechanical performance of asphalt's aggregate skeleton (2024)
Journal Article

This paper evaluates the feasibility of using 3D-printed lattice metamaterials as an alternative to capsules containing rejuvenators to enhance the self-healing capability of asphalt. The original purpose of these capsules is to encapsulate a rejuven... Read More about Energy-absorbing particles for enhanced mechanical performance of asphalt's aggregate skeleton.

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...

Stochastic properties of static friction (2020)
Journal Article

The onset of frictional motion is mediated by rupture-like slip fronts, which nucleate locally and propagate eventually along the entire interface causing global sliding. The static friction coefficient is a macroscopic measure of the applied force a... Read More about Stochastic properties of static friction.

Dynamic fields at the tip of sub-Rayleigh and supershear frictional rupture fronts (2019)
Journal Article

The onset of frictional motion at the interface between two distinct bodies in contact is characterized by the propagation of dynamic rupture fronts. We combine friction experiments and numerical simulations to study the properties of these frictiona...

A hybrid finite element‐spectral boundary integral approach: Applications to dynamic rupture modeling in unbounded domains (2018)
Journal Article

The finite element method (FEM) and the spectral boundary integral method (SBI) have both been widely used in the study of dynamic rupture simulations along a weak interface. In this paper, we present a hybrid method that combines FEM and SBI through...

Off-fault heterogeneities promote supershear transition of dynamic mode II cracks (2017)
Journal Article

The transition from sub-Rayleigh to supershear propagation of mode II cracks is a fundamental problem of fracture mechanics. It has extensively been studied in homogeneous uniform setups. When the applied shear load exceeds a critical value, transiti... Read More about Off-fault heterogeneities promote supershear transition of dynamic mode II cracks.
