Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Ground Surface Deformation Prediction Using Machine Learning Approaches

Journal of Electronic & Information Systems
This study aims to investigate the use of machine learning algorithms to predict the settlements of the ground surface triggered by tunneling using a shielding method. First, a 2D tunnel calculation scheme was proposed for nonlinear construction stage analysis using the “contraction” load, which can be used to simulate the soil volume loss.

Notes on the Vertical Deformations of the Ground Surface in the Central Part of the City of Tokyo.

Journal of Physics of the Earth, 1952
1. The vertical displacements of the ground surface in the central part of the city of Tokyo, which have been detected by levelling surveys repeated recently, consist of two components, namely, the sinking due to the shrinkage of the soft superficial soil layer and the displacement resulting from tilt of the underlying layer of harder material.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

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.

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.
