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 multi-scale 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 mini-symposium invites contributions on recent developments on peridynamic theory and multiscale coupling modeling for the simulation of complex material behavior.

如果您覺得這個研討會好，請幫我們轉發，謝謝！
近場動力學(PD)理論是國際上剛興起的基於非局部作用思想建立的一整套力學理論體系，該理論通過求解空間積分方程描述物質力學行為，避免了基於連續性假設建模和求解空間微分方程的傳統宏觀方法在面臨不連續問題時的奇異性[1]，所以特別適用於模擬材料自發地斷裂過程。然而，因為近場動力學的數學理論內容豐富且與傳統理論差別較大，目前的相關文獻又以英文表述為主，所以很多朋友在一開始學習時會遇到一些困難。因此，我於2016年9月建立了此微信公眾號（近場動力學討論班），希望通過自己的學習加上文獻翻譯和整理，降低新手學習近場動力學理論的入門門檻，分享國際上近場動力學的研究進展，從而聚集對近場動力學理論感興趣的華人朋友，為推動近場動力學理論的發展做一點兒貢獻！
