Demanding structural applications require a detailed knowledge of the materials response up to very late stages before failure. Ductile high-strength steels may undergo pronounced necking over majority their straining life; this makes reliable stress–strain characterization difficult, especially at dynamic rates, because self-heating from fast adiabatic dissipation promote thermal effects inter...

This work analyses the influence of intermediate strain rates, between 25 and 75 s−1, on compressive behaviour agglomerated cork. Quasi-static dynamic tests an cork with two different densities were carried out. complements previous research focused higher rates. The rate less studied properties as densification or Poisson ratio is also studied. Digital image correlation (DIC) applied to estima...

Extinction of premixed flames under non-uniform, unsteady strain is a phenomenon commonly observed in turbulent combustors. To assess the role inequity thermal and mass diffusion, represented by global Lewis number (Le) - defined as ratio mixture’s diffusivity to deficient species, on such extinctions, we present study counterflow twin-flames with various Le oscillating rates. Experimental resu...
