GiftBTE: An efficient deterministic solver for non-gray phonon Boltzmann transport equation
Yue Hu, Ru Jia, Jiaxuan Xu +5
Advances in nanotechnology have facilitated the exploration of submicron thermal transport. At this scale, Fourier's law is no longer applicable, and the governing equation for the…
A "parallel universe" scheme for crack nucleation in the phase field approach to fracture
Yihao Chen, Yongxing Shen
Crack nucleation is crucial in many industrial applications. The phase field method for fracture transforms the crack nucleation problem into a minimization problem of the sum of t…
An asynchronous variational integrator for the phase field approach to dynamic fracture
Zongwu Niu, Vahid Ziaei-Rad, Zongyuan Wu +1
The phase field approach is widely used to model fracture behaviors due to the absence of the need to track the crack topology and the ability to predict crack nucleation and branc…
A minimalistic approach to simulate multiple failure mechanisms of metal matrix fiber-reinforced composites by the phase field and cohesive zone models
Zhaoyang Hu, Xufei Suo, Feng Jiang +1
The mechanical properties of metal matrix fiber-reinforced composites depend on many aspects of their structure in a complicated way. In this paper, we propose a \emph{minimalistic…
Optimized phonon band discretization scheme for efficiently solving the non-gray Boltzmann transport equation
Yue Hu, Yongxing Shen, Hua Bao
Phonon Boltzmann transport equation (BTE) is an important tool for studying the nanoscale thermal transport. Because phonons have a large spread in their properties, the non-gray (…
A Manifold Learning Approach to Accelerate Phase Field Fracture Simulations in the Representative Volume Element
Yangyuanchen Liu, Kexin Weng, Yongxing Shen
The multiscale simulation of heterogeneous materials is a popular and important subject in solid mechanics and materials science due to the wide application of composite materials.…
A micromechanics-informed phase field model for brittle fracture accounting for the unilateral constraint
Yangyuanchen Liu, Cheng Cheng, Vahid Ziaei-Rad +1
We propose a new direction-dependent model for the unilateral constraint involved in the phase field approach to fracture and also in the continuous damage mechanics models. The co…
A Nonlocal Model for Dislocations with Embedded Discontinuity Peridynamics
Teng Zhao, Yongxing Shen
We develop a novel nonlocal model of dislocations based on the framework of peridynamics. By embedding interior discontinuities into the nonlocal constitutive law, the displacement…
Computing stress intensity factors for curvilinear cracks
Maurizio M. Chiaramonte, Yongxing Shen, Leon M. Keer +1
The use of the interaction integral to compute stress intensity factors around a crack tip requires selecting an auxiliary field and a material variation field. We formulate a fami…
