Abstract

Abstract This paper deals with the experimental and numerical analysis of three-point bending phenomenon on beam composite profiles. Flat rectangular test specimens made of carbon–epoxy composite, characterised by symmetric [0/90/0/90]s laminate ply lay-up, were used in this study. Experimental testing was carried out with a COMETECH universal testing machine, using special three-point bending heads. In addition, macroscopic evaluation was performed experimentally using a KEYENCE Digital Microscope with a mobile head recording real-time images. Parallel to the experimental studies, numerical simulations were performed using the finite element method in ABAQUS software. The application of the above-mentioned interdisciplinary research techniques allowed for a thorough analysis of the phenomenon of failure of the composite material subjected to bending. The obtained research results provided a better understanding of the failure mechanism of the composite material.

基于先进数值损伤模型的组合梁三点弯曲失效分析

摘要本文对梁复合材料型材三点弯曲现象进行了实验和数值分析。本研究采用对称的[0/90/0/90]s层压铺设的碳-环氧复合材料扁矩形试件。实验测试采用COMETECH万能试验机，采用专用三点弯曲头。此外，通过实验使用KEYENCE数字显微镜进行宏观评估，该显微镜带有记录实时图像的移动头。在实验研究的同时，在ABAQUS软件中采用有限元法进行了数值模拟。上述跨学科研究技术的应用，可以对复合材料在弯曲作用下的失效现象进行彻底的分析。所得研究结果为进一步了解复合材料的破坏机理提供了依据。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
