BoDy - Boudinage Dynamics

我们建议使用最先进的离散元和有限元模型，并结合对世界级露头的高分辨率野外研究，以更好地了解布丁的演化。我们将测试现有的运动学模型的力学有效性，并致力于开发一种新的税收经济学，其诊断标准建立在对包扎的完整和一致的机械理解的基础上。这个项目的目标是建立一个观测数据的反演，以获得关于流变学、应力、应变和涡度的信息。这个项目的重要性是双重的。通过在自然实验室中提供流变学、有效应力、应变和涡度的数据，它将改进地壳力学演化的模型。在勘探盐岩中的矿床和油气藏，防止蒸发岩中的钻探问题，以及预测潜在的核废料储存地点的硬石膏层结构等方面都有实际应用。

We propose to use state of the art Discrete Element and Finite Element models integrated with a high-resolution field study of a world-class outcrop, to better understand the evolution of boudins. We will test existing kinematic models for their mechanical validity, and aim to develop a new tax- onomy with diagnostic criteria based on a complete and consistent mechanical understanding of boudinage. The goal of this project is to build towards an inversion of observations to obtain informa- tion on rheology, stress, strain, and vorticity during the formation of boudins.The importance of this project is twofold. By providing data on rheology, effective stress, strain and vorticity in natural laboratories, it will improve models of the mechanical evolution of the crust. Practi- cal applications are in the exploration of ore deposits and hydrocarbon reservoirs encased in salt, prevention of drilling problems in evaporites, and prediction of the structure of boudinaged anhydrite layers in potential sites for nuclear waste storage.
