Ductile fracture modeling by phase field, Hencky strain elasticity and finite J2 plasticity using nonlocal operator method
Huilong Ren, Xiaoying Zhuang, Timon Rabczuk
A phase field model for ductile fracture considering Hencky strain and finite J2 plasticity is presented using the nonlocal operator method. A variational derivation of J2 plastici…
Bond-based nonlocal models by nonlocal operator method in symmetric support domain
Huilong Ren, Timon Rabczuk, Xiaoying Zhuang +1
This paper is concerned with the energy decomposition of various nonlocal models, including elasticity, thin plates, and gradient elasticity, to arrive at bond-based nonlocal model…
Nonlocal strong forms of thin plate, gradient elasticity, magneto-electro-elasticity and phase field fracture by nonlocal operator method
Huilong Ren, Xiaoying Zhuang, Erkan Oterkus +2
The derivation of nonlocal strong forms for many physical problems remains cumbersome in traditional methods. In this paper, we apply the variational principle/weighted residual me…
Higher order nonlocal operator method
Huilong Ren, Xiaoying Zhuang, Timon Rabczuk
We extend the nonlocal operator method to higher order scheme by using a higher order Taylor series expansion of the unknown field. Such a higher order scheme improves the original…
Dual-support smoothed particle hydrodynamics in solid: variational principle and implicit formulation
Huilong Ren, Xiaoying Zhuang, Timon Rabczuk +1
In this paper, we derive the dual-support smoothed particle hydrodynamics (DS-SPH) in solid in the framework of variational principle. The tangent stiffness matrix of SPH is obtain…
A nonlocal operator method for solving partial differential equations
Huilong Ren, Xiaoying Zhuang, Timon Rabczuk
We propose a nonlocal operator method for solving partial differential equations (PDEs). The nonlocal operator is derived from the Taylor series expansion of the unknown field, and…
Dual-support smoothed particle hydrodynamics for elastic mechanics
Zili Dai, Huilong Ren, Xiaoying Zhuang +1
In the standard SPH method, the interaction between two particles might be not pairwise when the support domain varies, which can result in a reduction of accuracy. To deal with th…
A new peridynamic formulation with shear deformation for elastic solid
Huilong Ren, Xiaoying Zhuang, Timon Rabczuk
We propose a new peridynamic formulation with shear deformation for linear elastic solid. The key idea lies in subtracting the rigid body rotation part from the total deformation.…
Dual-support Smoothed Particle Hydrodynamics
Huilong Ren, Zili Dai, Xiaoying Zhuang +1
In this paper we develop a dual-support smoothed particle hydrodynamics (DS-SPH) that naturally satisfies the conservation of momentum, angular momentum and energy when the varying…
Dual-horizon Peridynamics
Huilong Ren, Xiaoying Zhuang, Yongchang Cai +1
In this paper we develop a new Peridynamic approach that naturally includes varying horizon sizes and completely solves the "ghost force" issue. Therefore, the concept of dual-hori…
