Abstract

The mechanical behaviour of strain-hardening cement-based composites (SHCC) under monotonic tensile loading has been the subject of research for many years. The recent research on the SHCC's performance under cyclic loading has enabled the identification of a wide variety of damage phenomena different to those observed under monotonic loading. The article at hand first summarises the experimental evidence of such phenomena in the context of the material performance observed. On this basis, the mechanisms behind these phenomena are discussed and explained using rheological modelling.

摘要

多年来，应变硬化水泥基复合材料（SHCC）在单调拉伸载荷下的力学行为一直是研究的主题。最近关于SHCC在循环载荷下性能的研究，已经能够识别出与单调载荷下观察到的不同的各种损伤现象。本文首先在观察到的材料性能背景下总结了这些现象的实验证据。在此基础上，使用流变学模型对这些现象背后的机制进行了讨论和解释。
