A framework for dynamic full-flow penetrometer analysis
A framework for dynamic full-flow penetrometer analysis
The urgent need for renewable energy development to address the escalating challenges of climate change has been widely acknowledged in different sectors of offshore engineering. One aspect is the dynamic penetration of penetrometers into the seabed, a critical issue in offshore geomechanics that poses significant challenges for geotechnical analysis. The difficulties associated with shallow penetration depths in field tests and the pronounced high strain rate effects caused by objects moving through soil media have affected the adoption of dynamic penetrometers for site investigations in large-scale projects, such as offshore wind farms, and anchoring sites. Recent research work has led to the development of a prototype dynamic penetrometer, aimed at exploring soil properties at relatively shallow depths using the principles of soil dynamics. In this study, we present the speargun projectile penetrometer (SPP), which has been engineered to capture the dynamic response of sands subjected to impact loads using an external energy source. This study will also address several challenges of analysing the data obtained from physical modelling by the SPP and propose an analytical framework for this problem.
