Engineering Structures and Technologies, 2014 The paper focuses on the optimization of a perfectly elastic-plastic truss under repeated variable load. The improved mathematical model of truss volume minimization problem with strength, stiffness and stability constraints is presented. The assumptions

Subsurface Single‐Atom Catalyst Enabled by Mechanochemical Synthesis for Oxidation Chemistry
Angewandte Chemie, Volume 136, Issue 42, October 14, 2024.The mechanochemical approach has been shown to be an effective method of regulating the position of single atoms. Controlling single atoms at the surface or subsurface results in catalysts with very different adsorption properties, leading to different reaction mechanisms.

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

Journal of Civil Engineering and Management, 2002 The adapted plate load optimization problem is formulated applying the non-linear mathematical programming methods. The load variation bounds satisfying the optimality criterion in concert with the strength and stiffness requirements are to be identified.

Theorems of restricted dynamic shakedown
, 1993 Dynamic shakedown for a rate-independent material with internal variables is addressed in the hypothesis that the load values are restricted to those of a specified load history of finite or even infinite duration, thus ruling out the possibility-typical

Neohypoplasticity for Sand Coupled With the Generalized Intergranular Strain Concept
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 15, Page 3484-3508, 25 October 2025.ABSTRACT This work presents the coupling of the recently revisited advanced hypoplastic constitutive sand model called neohypoplasticity (NHP) with the more recently introduced concept of the generalized intergranular strain (GIS) to account for soil behavior due to small strains. The latter is essential for the simulation of cyclic deformations.

Friction Characterization and Mitigation in Large‐Scale 6DOF Multi‐Axial Hybrid Simulation
Earthquake Engineering &Structural Dynamics, Volume 54, Issue 9, Page 2283-2302, 25 July 2025.ABSTRACT In the last few decades, hybrid simulation has become widely used for understanding the response of structural components and systems under extreme loading conditions. Large‐scale, three‐dimensional (3D), multi‐axial testing facilities with six degrees of freedom (6DOF) are versatile testing systems that can be used for testing a variety of ...

Advanced Science, Volume 12, Issue 13, April 3, 2025.The oxidative generation of Cu(II) active sites in Cu‐exchanged zeolites for the CH4‐to‐CH3OH conversion has been studied. Complementary in situ/operando spectroscopic techniques highlight that the formation rate and the stability of different Cu(II) species are governed by their structure and the zeolite topology.
