This award provides travel support for 25 students, postdoctoral fellows, and early-career faculty from US institutions to attend the US Association for Computational Mechanics (USACM) Special Topic Conference “Quarter Century of Peridynamics” (PD25), which will be held 22-25 April 2024 in Tucson, Arizona. The main objective of the conference is to broaden the exposure of peridynamics (PD) modeling and simulation to a larger audience that may benefit from the advantages this approach provides to complex, previously unsolvable problems in science, engineering, and technology. Graduate students, post-docs, and participants from industry, national labs, and national agencies will be trained through their participation in the conference and associated short courses. The conference presents an ideal opportunity for networking to early career researchers specializing in modeling and simulation of material degradation and failure, and ways to reduce it (when protecting against damage is sought) or enhance it (as is needed in mining, recycling of materials, etc.). The conference organizers have sought to broaden participation from members of underrepresented groups and undergraduate students who aspire to learn more about PD modeling. These efforts will grow the pipeline of US researchers working on modeling and simulation of material failure and damage.Peridynamics (PD) was introduced in 2000 as a model of fracture and failure in materials and has recently experienced explosive growth in terms of the number of publications and research groups working on PD-related topics. PD is now reaching a broad range of research areas beyond fracture, including modeling of corrosion damage, growth of tumors, electromigration, simulating crushing of powders for medical tablets, and modeling of graphene layers. The major focus of PD modeling and simulation is reliability and safety of mechanical, civil, and aerospace systems, with a direct impact on reducing costs and improving performance of such systems. These effects have a direct impact on health, quality of life, and homeland security. The conference program includes three short courses, running in parallel, on different aspects of PD-based computational software applied to predicting fracture and damage in a variety of materials, including glass and ceramics, metals, and fiber-reinforced composites. These courses, presented by leaders on PD modeling and simulation, aim to provide participants with hands-on experience with PD solvers in a variety of settings, including running massively parallel computations, or coupling with commercial software like ANSYS and Abaqus.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项为25名学生，博士后研究员和美国机构的早期职业学院提供了旅行支持，他们将参加美国计算机械师协会（USACM）特别主题会议“ Peridynemics的四分之一世纪”（PD25）（PD25），该会议将于2024年4月22日至25日在亚利桑那州图森举行。会议的主要目的是扩大植物动力学（PD）建模和仿真的曝光率，向更大的受众群体扩大，这可能会受益于这种方法为科学，工程和技术中复杂，以前无法解决的问题提供的优势。将通过参加会议和相关的短期课程来培训研究生，职业生涯后以及行业，国家实验室和国家机构的参与者。会议为与早期职业研究人员建立联网的理想机会，专门研究材料降解和失败的建模和模拟，以及减少材料的方法（感知损害时）或增强材料的方法（如采矿，材料回收等所需的那样）。会议组织者已经感觉到，渴望了解更多有关PD建模的人的代表性不足的团体和本科生的参与。这些努力将增加美国研究人员的材料失败和损害模拟和模拟的渠道。2000年引入了毕生动力学（PD），作为材料中的断裂和失败的模型，最近在与PD相关主题上工作的出版物数量和研究小组的爆炸性增长。 PD现在已经达到了骨折以外的广泛研究区域，包括腐蚀损伤的建模，肿瘤的生长，电气移民，模拟医疗片剂的粉末和石墨烯层的建模。 PD建模和模拟的主要重点是机械，民用和航空系统的可靠性和安全性，对降低成本和改善此类系统的性能有直接影响。这些影响直接影响健康，生活质量和国土安全。会议计划包括三个短期课程，并并行运行，该课程在基于PD的计算软件的不同方面，用于预测各种材料的断裂和损坏，包括玻璃和陶瓷，金属以及纤维增强的复合材料。这些课程是由领导者在PD建模和模拟上介绍的，旨在为参与者提供各种环境中PD求解器的动手经验，包括运行众多平行的计算，或与ANSYS和ABAQUS等商业软件相结合。该奖项奖通过评估了NSF的法定任务，并通过评估了CRARITIAL的支持，并反映了CRCRITIAL的支持。
