Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

open access: yesAdvanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Variation in principal curvature of air-water interface inside and outside shear band of dense unsaturated sand [PDF]

open access: yesE3S Web of Conferences
Triaxial compression tests were conducted on dense unsaturated sand specimens under constant suction and constant water content conditions. X-ray micro-computed tomography (CT) scans were performed at different deformation stages to visualize the ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Aspects that affect the shear bands in numerical simulations of strain plane test using finite elements in a hypoplastic constitutive model

open access: yesRevista Técnica de la Facultad de Ingeniería, 2012
In conventional geomechanical analysis performed with the Finite Element Method, the orientation of the failure surface or shear band depends on the orientation of the elements.

Shear localization in a model glass

open access: yes, 2002
Using molecular dynamics simulations, we show that a simple model of a glassy material exhibits the shear localization phenomenon observed in many complex fluids. At low shear rates, the system separates into a fluidized shear-band and an unsheared part.

Non-linear oscillatory rheological properties of a generic continuum foam model: comparison with experiments and shear-banding predictions [PDF]

open access: yes, 2012
The occurence of shear bands in a complex fluid is generally understood as resulting from a structural evolution of the material under shear, which leads (from a theoretical perspective) to a non-monotonic stationnary flow curve related to the ...
