Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

HUMANITY, FROM PEACEFUL EXPLORATION OF OUTER SPACE TO ITS CONQUEST THROUGH SPACE FORCES, ANTI-SATELLITE WEAPONS AND STATE OF THE ART SPACE TECHNOLOGIES [PDF]
Annals: Series on Military Sciences, 2019 For a long period of time, usage of outer space for humankind was limited to observing outer space constellations, navigation and prediction of meteorological phenomena.

The intersection between space law and international human rights law
, 2017 The international legal regulation of outer space represents an ongoing challenge in terms of establishing and implementing frameworks that are appropriate means of global governance. Those of us who are concerned with the legal regulation of outer space

Fractional Spaces and Conservation Laws [PDF]
, 2018 In 1994, Lions, Perthame and Tadmor conjectured the maximal smoothing effect for multidimensional scalar conservation laws in Sobolev spaces. For strictly smooth convex flux and the one-dimensional case we detail the proof of this conjecture in the framework of Sobolev fractional spaces $W^{ s,1}$ , and in fractional $BV$ spaces: $BV^s$.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

The exclusive making of space law
Leiden Journal of International LawThe commons are defined by non-excludability – the idea that none can exclude another from access or use. Likewise, space lawyers portray their discipline’s origin story as uniquely egalitarian and inclusive, in part because of how it was made.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
