近场动力学领域最新、最全研究汇总:《Handbook of Peridynamic Modeling》一书终于出版发行了!


自2013年9月开始,在Bobaru教授、Foster教授、Geubelle教授和Silling博士的领导下组织国际上各个近场动力学理论的知名研究团队编写了此书,历时三年,将近600页,汇集了近年来各家关于近场动力学理论的重要研究成果。我也参与其中,撰写了本书第14章中关于能量基的耦合框架部分。


这本书对希望学习和从事近场动力学理论研究的同学和老师会有很大的借鉴作用。不过价格不菲,亚马逊上精装版卖200刀。经费充足的小伙伴们可以考虑购买,也可以购买电子版:首先需要一个Bookshelf账号,然后有在线和离线软件两种阅读方式。电子书的具体价格我不知道,应该比纸质书要便宜吧。

近场动力学(简称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的损伤和断裂过程。然而,因为PD模型的数学理论较深,且新概念多用英文表述,所以很多朋友在学习时会遇到一些困难。在朋友的启发下,我想到在微信上建立此公众号,希望将研究PD理论的朋友们聚集起来,分享PD研习路上的点点滴滴,一起解决各自的难题,共同推动PD理论的发展!
