The overall goal of the proposed research project is to develop, analyze and implement a novel set of contact formulations for higher order gradient materials, paving the way for further applications in the simulation of complex materials. Therefore, the concept of Mortar type methods, recently extended to general higher order domain decomposition problems in the context of IGA, will be reformulated and applied to contact of second and third gradient materials. Moreover, we will demonstrate convergence and accuracy of the proposed methodology compared to classical approaches. This allows us to limit the applicability and emphasise the necessity in specific situations depending on the material pairing and the interface topology.

该研究项目的总体目标是开发、分析和实施一套用于高阶梯度材料的新型接触配方，为进一步应用于复杂材料的模拟铺平道路。因此，迫击型方法的概念将被重新表述，并应用于第二和第三梯度材料的接触问题。此外，与经典方法相比，我们将证明所提出的方法的收敛和准确性。这使我们可以根据材料配对和接口拓扑结构限制其适用性，并强调在特定情况下的必要性。
