中文摘要
节理表面可能表现出各种脆性破坏细节的特征,但这些特征在结构分析中通常不被利用。该项目将在实验室条件下生成这些特征,试图为现场地质学家提供新的解释工具,以约束构造载荷、应变速率和循环载荷。研究结果若能成功应用于实际实例,将对脆性场变形研究具有实用价值。
英文摘要
9805324 Pollard Joint surfaces may exhibit features indicative of various details of brittle failure, but these are not commonly exploited in structural analysis. This project will produce these features under laboratory conditions in an attempt to provide new interpretative tools for field geologists to constrain tectonic loading, strain rates and cyclic loading. Results, if successful and scaled to actual examples would be of utility in brittle-field deformation studies.
