GRK 1627: Virtual Materials and Structures and their Validation

Vivace的第一阶段研究致力于开发健壮可靠的模拟工具，可用于对材料和结构进行虚拟实验。这些工具将在Vivace的第二和第三阶段得到进一步开发，并将应用于非均质材料的分析。重点之一将是验证数值工具，但也将有与模拟方法有关的新发展，如模型简化技术和自动代码生成。这些将应用于多尺度/多物理问题，包括不确定性和敏感性分析。与ENS Cachan的合作为博士生提供了一个富有成效的国际环境，构成了一个研究和开发可用于进行虚拟实验及其验证的新方法和数值模拟工具的论坛。在研究生院MUSIC(多尺度界面耦合方法)中，博士生的配置提供了一个多学科的工作环境，允许优秀的硕士研究生、博士生和相关的VIVACE博士后和其他培训小组之间的合作和科学交流。他们致力于新方法的实施，进行与材料和结构相关的虚拟实验，并进行验证。来自力学、结构分析、材料科学、机械工程和应用数学的PI的参与确保了广泛的知识基础，允许新的见解。与ENS Cachan LMT的同事们的强烈互动完成了Vivace在多尺度/多物理领域的研究概况以及与复合材料有关的相关实验方法。德国博士生留在En Cachan，法国博士生留在LUH，以积极的方式扩大了参与者的科学知识基础和经验范围。

The research within ViVaCE in its first phase was devoted to the development of robust and reliable simulation tools that can be used to perform virtual experiments on materials and structures. These tools will be further developed in the second and third phases of ViVaCE and will be applied to the analysis of heterogeneous materials. One of the major points will be the validation of the numerical tools, but there will be also new developments related to simulation methods, such as model-reduction techniques and automatic code generation. These will be applied to multi-scale/multi-physics problems including uncertainty and sensitivity analysis.The cooperation with the ENS Cachan provided to the PhD candidates a fruitful and international environment, that constitutes a forum for research and development of new methodologies and numerical simulation tools that can be used to perform virtual experiments and their validation. The collocation of the PhD candidates in the premises of the graduate school MUSIC (Multi-Scale Methods for Interface Coupling) provides a multidisciplinary working environment that allows for collaboration and scientific exchanges between excellent Master-students, PhD candidates and associated Post-Docs of ViVaCE and other training groups.In ViVaCE PhD candidates are working together in a multidisciplinary manner. They work on implementation of new methods, carry out virtual experiments related to materials and structures and validate these. The participation of PIs from mechanics, structural analysis, material science, mechanical engineering and applied mathemat-ics ensures a broad knowledge base that allows for new insights. The strong interaction with colleagues from the LMT of the ENS Cachan completes the research profile of ViVaCE in the areas of multi-scale/multi-physics and related experimental methods in connection with composite materials. The stay of German PhD candidates at ENS Cachan and vice versa of French PhD candidates at LUH enlarges the scientific knowledge base as well as the horizon of experience for the participants in a positive manner.
