A New Critical Plane Multiaxial Fatigue Criterion with an Exponent to Account for High Mean Stress Effect

open access: yesMetals
The mean stress effect remains a critical aspect in multiaxial fatigue analysis. This work presents a new criterion that, based on the classical Findley criterion, applies a material-dependent exponent to the mean normal stress term and includes the ...

The Elephant Trunk Skin Inspires a Highly Sensitive and Deformable, Yet Robust, Armor Skin

open access: yesAdvanced Science, EarlyView.
The study presents the elephant trunk‐inspired armor skin with tactile sensing (ETATS). The ETATS architecture stretches and compresses while resisting puncture and tear, and it enables optical detection of pressure and lateral strain. Morphology‐based decoupling of strain and pressure paves the way to sensitive and deformable, yet robust, soft‐robotic

A probabilistic high cycle fatigue model applied to cast Al-Si alloys [PDF]

open access: yes, 2013
In this work, the high cycle fatigue behavior of cast hypo-eutectic Al-Si alloys is investigated. It is observed that two different coexisting fatigue initiation mechanisms can occur in these materials depending on the presence of different ...

Microstructural characterization of creep anisotropy at 673K in the M5® alloy [PDF]

open access: yes, 2012
Zirconium alloy tubing is used in pressurized water nuclear reactors in order to prevent fissile material from leaking into the coolant. It can be the first safety wall of nuclear fuel, and is submitted to complex thermomechanical loadings.

Multiaxial Inverse Stress Analysis for Indentation Creep [PDF]

open access: yesMATEC Web of Conferences, 2019
This paper presents an extracting method of creep exponent and coefficient in Norton’s law from an indentation creep test analytically, assisted by a finite element analysis. Previous studies extracted only the creep exponent empirically with no theoretical verification.

Robotic Arm‐Assisted Conformal 3D Printing of Displays for Structural Electronics

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a robotics‐enabled platform combining 3D scanning and a 6‐DOF robotic arm for conformal printing on complex non‐planar structures. By maintaining nozzle perpendicularity, the system enables high‐fidelity direct ink writing on steep sidewalls, spherical surfaces, successfully demonstrating a fully printed 7‐segment dynamic display ...

Analysis of whisker-toughened ceramic components: A design engineer's viewpoint [PDF]

open access: yes, 1989
The use of ceramics components in gas turbines, cutting tools, and heat exchangers has been limited by the relatively low flaw tolerance of monolithic ceramics. The development of whisker toughened ceramic composites offers the potential for considerable
