Desiccation cracking
WebDec 20, 2024 · Desiccation cracking is a common phenomenon on Earth's surface. It is a typical form of soils' tensile failure caused by drying-induced tensile stress. Understanding soil tensile behavior during the drying process is of great significance for revealing the soil desiccation cracking mechanism. In this investigation, fiber Keywords Tensile strength WebMar 1, 2024 · Therefore, the ERT technique is an effective method to dynamic monitor the development of desiccation cracks and particularly reliable to map their positions. Khemissa et al. [27] compared the deformation features of undisturbed clay and compacted clay, and learned that the former is more likely to shrink than the latter.
