本文回顾了多尺度计算均匀化框架的非线性行为的非均匀薄平面壳。基于一些目前可用的方法的审查,计算均匀化计划的外壳上应用的平纹编织复合材料的代表性体积元素。分析了弯曲载荷对此类材料潜在失效模式的影响,重点研究了水泥基分层机理。接下来的注意力转移到破坏定位在砌体单元格。随后,最近开发的计算FE$^2$解决方案占在结构尺度上的RVE计算的基础上的损伤定位。
This paper reviews multi-scale computational homogenisation frameworks for the non-linear behaviour of heterogeneous thin planar shells. Based on a review of some of the currently available methods, a computational homogenisation scheme for shells is applied on representative volume elements for plain weave composites. The effect of flexural loading on the potential failure modes of such materials is analysed, focusing on the reinforcement-matrix delamination mechanism. The attention is next shifted toward failure localisation in masonry unit cells. Subsequently, a recently developed computational FE$^2$ solution scheme accounting for damage localisation at structural scales based on RVE computations is applied.
