Extended Stress–Strain Characterization of Automotive Steels at Dynamic Rates
Metals, 2022 Demanding structural applications require a detailed knowledge of the materials response up to the very late stages before failure. Ductile high-strength steels may undergo pronounced necking over the majority of their straining life; this makes a ...

Resonance-like Goss-Haenchen Shift induced by nano-metal films
, 2008 The influence of nano-metal films on the Goos-Haenchen shift (GHS) is investigated. The films deposited at the total reflecting surface of a perspex prism/air have a sheet resistance varying between Z = 25 and 3 000 Ohm.
