Mechanical Properties of Frozen Glacial Tills due to Short Periods of Thawing
Frontiers in Earth Science, 2021 Due to the warming climate, glacier retreat has left massive glacial tills in steep gullies; ice in the soil is prone to change phase resulting in the decrease of the ice strength and bonding of soil particles; collapse of thawing tills can lead to ...

Fracture of granular materials composed of arbitrary grain shapes: A new cohesive interaction model [PDF]
, 2016 Discrete Element Methods (DEM) are a useful tool to model the fracture of cohesive granular materials. For this kind of application, simple particle shapes (discs in 2D, spheres in 3D) are usually employed.

Contact mechanics for randomly rough surfaces [PDF]
, 2006 When two solids are squeezed together they will in general not make atomic contact everywhere within the nominal (or apparent) contact area. This fact has huge practical implications and must be considered in many technological applications.

Numerical modeling of friction stir welding using the tools with polygonal pins
Defence Technology, 2015 Friction stir welding using the tools with polygonal pins is often found to improve the mechanical strength of weld joint in comparison to the tools with circular pins. However, the impacts of pin profile on the peak temperature, tool torque and traverse
