摘要

预测结构所能承受的临界荷载和正确的裂缝路径是一个重要的科学和实用问题。这便是伤害机制出现的触发因素。在过去的几十年里，许多模型已经显示出它们预测临界载荷和裂纹路径的能力。我们可以引用厚层集模型（TLS）、相场损伤模型、周动力学和最近的唇场损伤模型。这项工作旨在展示PhaFiDyn软件通过统一的相场损伤模型公式来预测裂纹路径的能力。PhaFiDyn是在FeniCS上实现的，FeniCS是一个开源的有限元库。利用文献中的数值和实验结果进行了验证。PhaFiDyn很容易模块化，允许扩展这个实现。

PhaFiDyn: An explicit dynamic phase field damage model implementation

Predicting the critical load that structures can sustain and the right crack path is an important scientific and practical issue. This reason is the trigger for the appearance of the damage mechanics. During these last decades, many models have shown their ability to predict both critical loads and crack paths. We can cite thick-level set models (TLS), phase field damage models, peridynamics, and more recently Lip-Field damage model. This work aims to show the capability of the PhaFiDyn software to predict crack paths with the unified formulation of the phase field damage model. PhaFiDyn is implemented on FeniCS, an open-source finite element library. Validation test is realized with numerical and experimental results from the literature. PhaFiDyn is easily modular, allowing for expansion of this implementation.

期刊介绍： SoftwareX aims to acknowledge the impact of software on today''s research practice, and on new scientific discoveries in almost all research domains. SoftwareX also aims to stress the importance of the software developers who are, in part, responsible for this impact. To this end, SoftwareX aims to support publication of research software in such a way that: The software is given a stamp of scientific relevance, and provided with a peer-reviewed recognition of scientific impact; The software developers are given the credits they deserve; The software is citable, allowing traditional metrics of scientific excellence to apply; The academic career paths of software developers are supported rather than hindered; The software is publicly available for inspection, validation, and re-use. Above all, SoftwareX aims to inform researchers about software applications, tools and libraries with a (proven) potential to impact the process of scientific discovery in various domains. The journal is multidisciplinary and accepts submissions from within and across subject domains such as those represented within the broad thematic areas below: Mathematical and Physical Sciences; Environmental Sciences; Medical and Biological Sciences; Humanities, Arts and Social Sciences. Originating from these broad thematic areas, the journal also welcomes submissions of software that works in cross cutting thematic areas, such as citizen science, cybersecurity, digital economy, energy, global resource stewardship, health and wellbeing, etcetera. SoftwareX specifically aims to accept submissions representing domain-independent software that may impact more than one research domain.
