Evaluating Energy Absorption Performance of Filled Lattice Structures

Advanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

On the Thermal Deformation of Limit Gauge

Journal of the Japan Society of Precision Engineering, 1952
In the mass production, limit gauges are generally used to measure the machine parts. The thermal deformation of gauge in use is changed by the time and the method of holding, which is researched here.With the 50 millimetre limit gauge, the maximum deformation after holding 30 minutes is about 4.0μ and this is nearly equal to the working tolerance of ...

Deformations of the Earth and the Thermal Core-Mantle Couplings

Journal of geomagnetism and geoelectricity, 1993
Zonal modes of mantle deformation may couple with the Earth's rotational motion. Increases of the LOD (slowing down of the Earth's rotational speed) suggest a coupling with increases of the vertical in the low latitude zone. This relation may be due to the angular momentum redistribution in the mantle associated with motions in the fluid core.

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 ...
