Explanation of the discrepancy between the measured and atomistically calculated yield stresses in body-centered cubic metals [PDF]
We propose a mesoscopic model that explains the factor of two to three discrepancy between experimentally measured yield stresses of BCC metals at low temperatures and typical Peierls stresses determined by atomistic simulations of isolated screw ...

Review of torque models for offshore helical piles [PDF]
Helical (or screw) piles, sometimes defined as anchors, are a piled system consisting of one or multiple helices welded along the shaft. Piles are installed by applying a torque to the shaft.

Research on uplift mechanism of screw pile
This paper uses numerical simulation software to study the bearing characteristics of screw pile with pitch after installation. The selected soil is single layer sandy soil, and the blade is buried in deep burial mode. Based on the numerical simulation results, the vertical bearing characteristics of single spiral pile and ordinary bladeless pile are ...
