Numerical Investigation of Preload Process of Bolted Joint with Superelastic Shape Memory Alloy
Metals, 2018 A phenomenological constitutive model is developed to describe the uniaxial transformation ratcheting behaviors of the superelastic shape memory alloy (SMA) by employing a cosine–type phase transformation equation with the initial martensite ...

Microstructural Effects on Thermal-Mechanical Alleviation of Cold Dwell Fatigue in Titanium Alloys
Crystals, 2022 Cold dwell fatigue is a well-known problem in the titanium components of aircraft engines. The high temperature and low dwell stress of in-service conditions have been reported to give rise to dwell fatigue resistance through a thermal-mechanical ...

Pipeline Stress Test Simulation Under Freeze-Thaw Cycling via the XGBoost-Based Prediction Model
Frontiers in Earth Science, 2022 This study conducted ten freeze-thaw cyclic tests to clarify the effect of freeze-thaw cycles on the forces acting on the buried oil pipeline. The stress evolution in the Q345 steel pipeline versus the number of freeze-thaw cycles was obtained.

Light‐Driven Out‐of‐Equilibrium Helicity Control in a Diarylethene–Helicene Photosystem
Angewandte Chemie, EarlyView.Distinct energy landscapes of different helicities in the open and closed states of a diarylethene–helicene photoswitch enable a light‐driven energy ratchet. Helix inversion occurs selectively in the closed form, and the resulting helicity is transferred and kinetically trapped upon ring opening, generating a persistent out‐of‐equilibrium chiral state ...

Micromechanical investigation of soil plasticity using a discrete model of polygonal particles [PDF]
Theoretical and Applied Mechanics, 2008 The mechanical behavior of soils has been traditionally described using continuum-mechanics-based models. These are empirical relations based on laboratory tests of soil specimens.
