An international team of researchers have observed a phenomenon called virtual melting in colloidal crystals. They studied how it helps enable changes from one crystalline structure to another ...

When the melt emerges, the extrudate moves away from the die face at a constant speed, resulting in the outer layers being suddenly stretched and may tear. Incidence of Sharkskin Experiments have ...

As the melting of ice is an abrupt phase transition, this decrease in friction with increasing sliding speed occurs more slowly than might be anticipated. Persson proposes two possible explanations.

Shear stiffness and friction mechanics of single-layer graphene measured for the first time. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2012 / 02 / 120214121848.htm ...

It is possible to characterize the shear thinning behavior of thermoplastic materials using a Flow Rate Ratio (FRR) test method in an extrusion plastometer (melt indexer). This test method, “Procedure ...

Now researchers have found out how thin layers of noble gases like helium and metals like aluminum melt in confined spaces by topological excitations. In the study, the layers were confined ...

As a result, unmanaged shear-induced melt variations can influence the formation of every injection molded plastic part. The issues can include warpage, residual stresses and mechanical properties.

Comparatively, the melting of 2D solids, mediated by dislocations-unbinding, is much better understood, and the theory that describes it led to the 2017 Nobel prize in physics for Kosterlitz and ...
