Simulation of complex material behavior presents huge challenges in computational science and engineering nowadays. Overcoming those challenges requires the development of novel mathematical models and computational methods. Examples of such challenges in classical solid mechanics include the characterization of the microstructure dependence of the material response, as well as the simulation of material failure and damage; similarly, the description of coupling multiscale behaviors represents a challenge in classical theories. Peridynamics, as a new nonlocal theory, offers an alternative approach that avoids difficulties arising in classical local theories in the description of complex material behavior. Additionally, peridynamics as a nonlocal continuum model can be applied to coarse grained molecular dynamics, potentially for bridging the atomistic scale to the continuum scale. Computational implementations of a peridynamic model, however, cause huge computational cost and incompatibility with tractions like boundary conditions. Multiscale coupling strategies that bridge local and nonlocal models seem to provide a solution to both the computational expense and the boundary treatment. Multiscale coupling methods, in general, refer to the class of mathematical and computational techniques for the problems that exhibit characteristic features at multiple scales. Several of these methods have been proposed in past years for the effective prediction of the material response in, e.g., composites and heterogeneous media. This minisymposium invites contributions on recent developments on peridynamic theory and multiscale coupling modeling for the simulation of complex material behavior.

近场动力学(PD)理论是国际上刚兴起的基于非局部作用思想建立的一整套力学理论体系,该理论通过求解空间积分方程描述物质力学行为,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[1],所以特别适用于模拟材料自发地断裂过程。然而,因为近场动力学的数学理论内容丰富且与传统理论差别较大,目前的相关文献又以英文表述为主,所以很多朋友在一开始学习时会遇到一些困难。因此,我于2016年9月建立了此微信公众号(近场动力学讨论班),希望通过自己的学习加上文献翻译和整理,降低新手学习近场动力学理论的入门门槛,分享国际上近场动力学的研究进展,从而聚集对近场动力学理论感兴趣的华人朋友,为推动近场动力学理论的发展做一点儿贡献!
