Gabriel Karam will be presenting The Effects of Environmental Controls on Epigenetic Ice-Wedge Cracking.
Date: 8 May 2024
Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).
Ice-wedge polygons are a widespread periglacial feature in the continuous permafrost regions. To better understand the mechanical aspects of their formation, the extended finite-element method was employed to simulate the cracking process. Four case studies will be presented, which evaluate the effects different environmental controls and explore the growth of wedges over multiple years.
