       报告摘要： In this presentation, the fundamentals of homogenization techniques applied to mechanics will be presented. These methods make it possible to estimate the macroscopic behavior of heterogeneous materials and to establish a link between macroscopic and local behaviors, in each of the material's phases. Mean field homogenization schemes (analytical approach) and full field homogenization (numerical approach) will be introduced and illustrated for different types of materials. (本报告将介绍应用于力学的均匀化技术的基本原理。估算异质材料的宏观行为，建立材料各个相态中宏观与局部行为之间的联系。同时也将介绍不同类型材料的平均场均匀化方案(解析法)和全场均匀化(数值法)。)

       报告人简介：

          Ludovic Cauvin, is an associate professor at Université de Technologie deCompiègne (UTC) in France. He received his PhD from Lille State University, France, under the guidance of Professor Djimedo Kondo (Sorbonne Université, Paris, France). His research, conducted within the "Computational Mechanics" research group at the Roberval Laboratory, UTC, France, focuses on multi-scale modeling of heterogeneous materials. This includes predicting the mechanical behavior of polycrystalline metals, nanocomposites, and nanoporous materials. He employs analytical and/or numerical strategies to establish a connection between microstructural information and mechanical behavior at different scales. He has successfully supervised 6 PhD candidates and provided guidance to numerous Master's interns.At the Mechanics Department of the Université de Technologie de Compiègne, he is responsible for students specializing in computational mechanics. This specialization covers various fields such as statics, dynamics, optimization, biomechanics, and more.
