By identifying the key characteristic "structural scales" that dictate the resistance of a porous metallic glass against buckling and fracture, stochastic highly porous metallic-glass structures are designed capable of yielding plastically and inheriting the high plastic yield strength of the amorphous metal. The strengths attainable by the present foams appear to equal or exceed those by highl...

This paper will focus on aspects of the advanced analysis and underlying behavior of composite structures with concrete-filled steel tube (CFT) columns. Through a detailed examination of the results of a suite of full-scale slender CFT beam-column tests, insight into the cyclic behavior of such members is gained, specifically pertaining to local buckling of the steel tube and the plastic hinge ...

The buckling of rate dependent structures is not a topic often discussed in the literature. Methods to predict such exist, but only few experimental works have been published, and even less when considering thick shell structures. In this work we are interested elasto-visco-plastic hemi-egg shells. We follow modelling/experimental approach analyse problem. Buckling experiments at room temperatu...

The compressive resistance of truncated nanocone lattices produced by lithography and etching steps on Si or Ge wafers to get superhydrophobic antireflective light-transmitting windows, as well the protection efficiency alumina diamond coatings, is investigated numerical simulations elastic buckling, nanocompression tests. latter reveal limits an analysis, since stress at top cones high enough ...

Advances in additive manufacturing have enabled a new generation of materials with advantageous properties inherent to their architecture. Recently, architected periodic arrangements plates, called plate-lattice materials, been developed reach theoretical least upper bounds for stiffness and strength isotropic materials. This work investigates the buckling behavior several architectures relativ...
