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 ...

Kuhn-tucker conditions in shakedown problems
Journal of Civil Engineering and Management, 1996 An elastic perfectly plastic structure at shakedown to given cyclić loading is under consideration. The stress-strain field of dissipative system in general is related to the history of loading. And only in a particular case, i.e.

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.

The Shakedown of Circular Arches for Movable Loads
Engineering Transactions, 1975 The static approach is applied to method analysis of arches under movable loads. The shakedown load value cad be computed if the distribution of residual stresses is known, and limits of passive processes are evaluated in discrete numbers of the cross ...
