A cyclic elasto-plastic constitutive model based on a non-linear kinematic hardening rule for
sand is proposed. Three points are incorporated into the model: a new flow rule, a …

The phenomenon of liquefaction is one of the most important subjects in Earthquake
Engineering and Coastal Engineering. In the present study, the governing equations of such …

We have introduced two series of two-phase solvent systems which facilitate the systematic
search for the solvent systems suitable for high-speed counter-current chromatography. The …

Delayed cerebral ischemia is the most feared cause of secondary injury progression after
subarachnoid hemorrhage. Initially thought to be a direct consequence of large artery spasm …

Background Guidelines recommend treating patients with an internal carotid artery near
occlusion (ICANO) with best medical therapy (BMT) based on weak evidence. Consequently, …

A generalised continuum model for granular media is derived by direct homogenisation of
the discrete equations of motion. In contrast to previous works on this topic, continuum …

In this paper, localized deformation in partially saturated sand was investigated quantitatively
using microfocus X-ray computed tomography (CT) and an image analysis of the CT …
