The effect of weld residual stresses and their re-distribution with crack growth during fatigue under constant amplitude loading [PDF]

, 2010
In this work the evolution of the residual stresses in a MIG-welded 2024-T3 aluminium alloy M(T) specimen during in situ fatigue crack growth at constant load amplitude has been measured with neutron diffraction.

Contributions to the Dynamic Regime Behavior of a Bionic Leg Prosthesis

Biomimetics, 2023
The purpose of prosthetic devices is to reproduce the angular-torque profile of a healthy human during locomotion. A lightweight and energy-efficient joint is capable of decreasing the peak actuator power and/or power consumption per gait cycle, while ...

Stress Adaptation [PDF]

Microbiology Spectrum, 2017
ABSTRACT Fungal species display an extraordinarily diverse range of lifestyles. Nevertheless, the survival of each species depends on its ability to sense and respond to changes in its natural environment. Environmental changes such as fluctuations in temperature, water balance or pH, or exposure to chemical insults such as ...
