Article summary:
1. This article discusses the complexity of concrete behavior and the need for theoretical research to better understand it.
2. It proposes a procedure for generating random aggregate structures (RAS) with prescribed shapes and sizes, which can be used in mesoscopic studies of concrete.
3. The paper also describes an advancing front approach for generating finite element meshes that accurately follow the boundaries between aggregates and mortar matrix.
Article analysis:
The article is generally reliable and trustworthy, as it provides a detailed overview of the complexities of concrete behavior and how mesoscopic analysis can be used to better understand it. The proposed procedure for generating random aggregate structures is well-explained, with clear descriptions of how rounded and angular aggregates are generated, as well as how their size and spatial distributions are simulated. Furthermore, the advancing front approach for generating finite element meshes is described in detail, including how it can be used to accurately follow the boundaries between aggregates and mortar matrix.
The article does not appear to have any major biases or one-sided reporting; instead, it presents a balanced view on the complexities of concrete behavior and how mesoscopic analysis can help address them. All claims made in the article are supported by evidence from previous research studies, making them reliable and trustworthy. Additionally, all potential risks associated with mesoscopic analysis are noted throughout the paper.
The only potential issue with this article is that some counterarguments or alternative approaches may not have been explored in sufficient depth; however, this does not significantly detract from its overall reliability or trustworthiness.
