The boundary element method of peridynamics
نویسندگان
چکیده
The peridynamic theory brings advantages in dealing with discontinuities, dynamic loading, and nonlocality. integro-differential formulation of peridynamics poses challenges to numerical solutions complicated practical problems. Some important issues attract much attention, such as the computation infinite domains, treatment softening boundaries due an incomplete horizon, time accumulation error processes. In this work, we develop boundary element method (PD-BEM). examples demonstrate that PD-BEM exhibits several features. First, for nondestructive cases, can be one two orders magnitude faster than meshless particle (PD-MPM) directly discretizes computational domains; second, it eliminates error, thus conserves total energy better PD-MPM; third, does not exhibit spurious phenomena. For destructive cases where new emerge during loading process, propose a coupling scheme PD-MPM is applied cracked region uncracked significantly reduced.

Evaluation of Fracture Parameters by Coupling the Edge-Based Smoothed Finite Element Method and the Scaled Boundary Finite Element Method
This paper presents a technique to evaluate the fracture parameters by combining the edge based smoothed finite element method (ESFEM) and the scaled boundary finite element method (SBFEM). A semi-analytical solution is sought in the region close to the vicinity of the crack tip using the SBFEM, whilst, the ESFEM is used for the rest of the domain. As both methods satisfy the partition of unity...

Solidification Problems by the Boundary Element Method
This paper elaborates on the analysis and design of the solidification of pure metais. In the first part of this paper, a direct analysis is presented for the motion of the solid-Iiquid freezing interface and the time-dependent temperature field. An iterative implicit algorithm has been developed for this purpose using the boundary element method (BEM) with time dependent Green’s functions and ...

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
