Dual‐horizon peridynamics
Huilong Ren,Xiaoying Zhuang,Xiaoying Zhuang,Yongchang Cai,Yongchang Cai,Timon Rabczuk,Timon Rabczuk +6 more
TL;DR: In this article, a dual-horizon peridynamics (DH-PD) formulation is proposed to solve the ghost force issue by considering the unbalanced interactions between the particles with different horizon sizes.

Effects of Size and Aggregation/Agglomeration of Nanoparticles on the Interfacial/Interphase Properties and Tensile Strength of Polymer Nanocomposites
TL;DR: It is found that a thick interphase cannot produce high interfacial/interphase parameters and significant mechanical properties in nanocomposites because the filler size and aggregates/agglomerates also control these terms.

Fracture properties prediction of clay/epoxy nanocomposites with interphase zones using a phase field model
Mohammed A. Msekh,Mohammed A. Msekh,N. H. Cuong,Goangseup Zi,Pedro M. A. Areias,Xiaoying Zhuang,Timon Rabczuk +6 more
TL;DR: In this paper, a phase field approach is employed to model fracture in the matrix and the interphase zone of the polymeric nanocomposites (PNCs) while the stiff clay platelets are considered as linear elastic material.

A phase-field modeling approach of fracture propagation in poroelastic media
TL;DR: In this paper, a phase field model for fracture in poroelastic media is proposed, where the fracture propagation is driven by the elastic energy where the phase field is used as an interpolation function to transit fluid property from the intact medium to the fully broken one.

Fast parallel algorithms for short-range molecular dynamics
TL;DR: In this article, three parallel algorithms for classical molecular dynamics are presented, which can be implemented on any distributed-memory parallel machine which allows for message-passing of data between independently executing processors.
