Increased shear strength in frictional soil
, 2022 Limit equilibrium analysis (LEA) of slope stability is the main concept in evaluating existing structures and for designing of new ones. When doing a LEA cohesion c’ and friction angle φ’ are conventionally used for strength determination. Since LEA does not properly take consideration of factors contributing to increased shear strength in frictional ...

Harnessing Phase Separation for the Development of High‐Performance Hydrogels
Advanced Science, EarlyView.ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Demo 03-05 Surface Dependence of Friction
, 2001 This demonstration illustrates that the frictional force between different surfaces is very different. Four identical brass blocks are placed on strips of four different materials, and one end of the device is raised, as indicated in Figure 1, until ...

Advanced Science, EarlyView.Local stress concentration disrupts metabolic homeostasis and induces inflammation in the nucleus pulposus (NP), thereby accelerating intervertebral disc degeneration (IDD). A biomimetic HA/ChS hydrogel millimeter sphere (ChS@HM) is developed to enable synergistic stress dispersion and sustained hydration lubrication.

Friction behaviors in incremental sheet forming with rolling and sliding friction
FrictionThe tribological mechanisms governing microstructure evolution in incremental sheet forming (ISF) were investigated through comparative analysis of three friction modes: sliding friction (ISF-SF), rolling friction (ISF-RF), and frictionless free ...
