Creep-fatigue life assessment of cruciform weldments using the linear matching method

open access: yes, 2013
This paper presents a creep-fatigue life assessment of a cruciform weldment made of the steel AISI type 316N(L) and subjected to reversed bending and cyclic dwells at 550C using the Linear Matching Method (LMM) and considering different weld zones.

Neohypoplasticity for Sand Coupled With the Generalized Intergranular Strain Concept

open access: yesInternational 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

open access: yesEarthquake 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 ...

Surface adhesion and hardening effects on elastic–plastic deformation, shakedown and ratcheting behavior of half-spaces subjected to repeated sliding contact

open access: yesInternational Journal of Solids and Structures, 2013
AbstractDeformation of homogeneous elastic-perfectly plastic (EPP) and elastic-linear kinematic hardening plastic (ELKP) half-spaces due to repeated adhesive sliding contact is examined with a two-dimensional finite element model. Interfacial adhesion is modeled by nonlinear springs with a force-distance constitutive relation derived from the Lennard ...
