Peridynamics is a non-local formulation of continuum mechanics that is oriented toward deformations with discontinuities, especially fractures. Originally, bond-based peridynamic was introduced, [1] wherein, internal interaction forces between a material point and all the other ones with which it can interact, are modeled as a centr0al force ...

近场动力学（peridynamic）为描述材料破坏与断裂发展提供了新的模型与方法。 传统局部理论认为物质点仅与其直接邻域作用，并且由平衡方程控制，与直接邻域交换能量、动量、质量；从而经典理论材料某点的应力仅仅取决于材料该点形变。 LFEM + traditional FEM. 裂纹尖应力无穷大（奇异性条件），应变能有限。 应用LFEM 改进传统有限元算法：处理该奇异性条件，使得裂纹尖端成为边界条件（额外定义），不需要由控制方程PDE求解，因而涉及材料求解域的空间重新划 …

近场动力学(PeriDynamics，PD)兼有分子动力学方法和无网格方法的优点，避免了基于连续性假设建模和求解空间微分方程的传统宏观方法在面临不连续问题时的奇异性，又突破了经典分子动力学方法在计算尺度上的局限，在宏/微观不连续力学问题分析中均表现出很 ...

Peridynamics is a new continuum mechanics formulation. It was originally developed by Dr. Stewart Silling in 2000. In order to determine the deformation response of materials and structures subjected to external loading conditions, classical continuum mechanics (CCM) was introduced by disregarding the atomistic structure.

This web page and people behind it are committed to the further development of Peridynamic theory and Peridynamic community. Find out more about the Peridynamic theory, what it can be used for and how you can help and contribute to the Peridynamic community.

Removing the computational challenges inherent in the classical continuum mechanics, peridynamics has the capability to address challenging problems across different disciplines.

This book presents the peridynamic theory, which provides the capability for improved modeling of progressive failure in materials and structures, and paves the way for addressing multi-physics and multi-scale problems.
