Previous research has consistently found that introducing metastable retained austenite (RA) as a second phase retards the failure of steel under fatigue. However, the reasons for this benefit are not understood. Accordingly, the properties of RA mos

Study of the effect of strain rate on the in-plane shear and transverse compression response of a composite ply using computational micromechanics

Autor: Mario Rueda-Ruiz, Miguel Herráez, Federico Sket, Francisco Gálvez, Carlos González, Jon M. Molina-Aldareguia

The use of composite materials for structures subjected to impacts requires a deep understanding about the dynamic behaviour of the material. To this end, a physically-based computational micromechanics simulation tool has been developed to predict f

In advanced ceramics, improving toughness usually relies on the introduction of a soft metallic or polymeric ductile phase, which decreases the mechanical properties. Some natural materials are strong, stiff and tough due to a combination of mechanis
