Abstract

In order to move towards discrete analyses of soil behaviour, we need to develop a new range of apparatus and testing techniques. The lecture describes attempts to develop these new apparatus and presents data for a range of coarse-grained geomaterials at the single particle scale. The roles of the particle morphology and hence geological origin are discussed and are shown to influence both the contact mechanics and particle breakage behaviour. The mechanics of single particles are shown to be more complex than generally assumed and will require new means of modelling to account for the significant plasticity that occurs at particle contacts and patterns of breakage that are strongly influenced by the origins of particles and their effect on their morphology.

第 7 届毕晓普讲座：中尺度和微尺度的粗粒度土工材料力学

为了对土壤行为进行离散分析，我们需要开发一系列新的仪器和测试技术。讲座介绍了开发这些新仪器的尝试，并展示了一系列粗粒土工材料在单颗粒尺度上的数据。讲座讨论了颗粒形态以及地质起源的作用，并展示了这些作用对接触力学和颗粒破碎行为的影响。研究表明，单颗粒力学比一般假设的要复杂得多，需要新的建模方法来解释颗粒接触处发生的显著塑性以及受颗粒来源及其形态影响很大的断裂模式。

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.
