Reduced single-walled carbon nanotubes (r-SWCNT) are shown to react readily at room temperature under inert atmosphere conditions with epoxide moieties, such as those in triglycidyl p-amino phenol (TGAP), to produce a soft covalently bonded interface around the SWCNT. The soft interface is compatible with the SWCNT-free cross-linked cured matrix and acts as a toughener for the composite. Incorp...
High manganese austenitic steel has attracted increasing attention for its application in liquefied natural gas storage tank materials due to excellent ductility and low cost. This paper presents an overview of the research progress high recent years. As a structural material used at temperature environment, should not only have certain strength, but also good toughness prevent brittle fracture...
Abstract Advanced high-strength steels are key structural materials for the development of next-generation energy-efficient and environmentally friendly vehicles. Medium Mn steel, as one latest generation advanced steels, has attracted tremendous attentions over past decade due to its excellent mechanical properties. Here, state-of-the-art developments medium steel systematically reviewed with ...
Summary Mantis shrimps use their dactyl club to strike multiple high-velocity impacts against stiff and hard surfaces. To sustain the loads dissipate energy, has evolved a complex multiscale organization segmented in an impact surface, region, periodic region. Composed essentially of nanoparticles, mineralized chitin microfibers, proteins, each region exhibits microstructural specifici...
In this paper Mode I steady state crack growth in single crystal ferroelectric materials is investigated. Specifically, the fracture toughness enhancement due to domain switching near a steadily growing crack tip is analyzed. For this purpose, an incremental phenomenological constitutive law for single crystal ferroelectric materials is implemented within a finite element model to calculate the...
