Nucleation and detachment of polystyrene nanoparticles from plowing-induced surface wrinkling
Applied Surface Science Advances, 2021 We report the formation of spherical particles (up to 250 nm in diameter) from polystyrene surfaces repeatedly scratched by atomic force microscopy nanotips (nominal radius < 10 nm) along a series of parallel lines. The particles nucleate from the crests

Multiscale modelling of crazing in glassy polymers under cyclic loading [PDF]
Crazing is the primary damage mechanism in amorphous thermoplastics, enabling load transfer and enhancing fracture toughness. This dissertation develops a multiscale model for crazing, combining molecular dynamics and continuum micromechanics to ...

Dilatometry of Steel for the Production of 5.56 mm Calibre Rifle Barrels [PDF]
Problemy Mechatroniki, 2021 During high rates of fire, the bore of the firearm barrel is exposed to high temperatures. This exposure induces structural changes in the barrel material, which is especially significant for the substrate of the galvanic chrome plating.

A systematization of glaze spalling in azulejos
Conservar Património, 2016 The detachment of the glaze in azulejos is the ultimate form of decay, since it leads to the loss of the pictorial content. The detachment is usually considered in a diffuse way, however a close observation allows recognizing several types, often related
