Experimental study on ratcheting behavior of eutectic tin-lead solder under multiaxial loading

, 2019
A series of uniaxial and multiaxial ratcheting experiments have been conducted on 63Sn-37Pb solder alloys. It is shown that eutectic tin-lead solder is cyclic softening under uniaxial, pure torsional and axial/torsional ratcheting loading. Even low-level

Microsphere‐Modulated Sensing‐in‐Energy Supercapacitor With Self‐Filtering Ultra‐Large Signal Under High‐g Shocks

Advanced Science, EarlyView.
To overcome severe signal oscillation under extreme impact conditions, this work presents a Sensing‐in‐Energy microdevice which integrates a MEMS inertial structure directly within a supercapacitor electrolyte cavity. Utilizing shock‐driven transient contact and electrolyte damping for signal self‐filtering, it achieves weak‐oscillation, large ...

The effect of microstructure on the fatigue behavior of titanium alloy graded porous structures fabricated by selective laser melting

Journal of Materials Research and Technology, 2023
The bionic-inspired Ti–15Mo gradient porous structures were fabricated by selective laser melting (SLM) for the first time in this work. The compression-compression fatigue behavior of functional gradient Ti–15Mo porous structures is investigated, with ...

Evolution of Physical Intelligence Across Scales

Advanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

The Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Evaluation of the ratcheting behavior of Cr-Mo steel used in CNG tank

Results in Engineering
Compressed natural gas (CNG) tanks, due to the frequent filling and emptying during their service life, are constantly subjected to fatigue loading on the tank's wall, which causes premature failure.
