Simulation of cyclic plastic deformation response in SA333 C–Mn steel by a kinematic hardening model

, 2010
Cyclic plasticity deals with non-linear stress–strain response of materials subjected to external repetitive loading. An effort has been made to describe cyclic plastic deformation behavior of the SA333 C–Mn steel by finite element based plasticity model.

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

On Prediction of 3d Stress State in Elastic Shell by Higher-order Shell Formulations [PDF]

, 2008
In this work we study the accuracy of modem higher-order shell finite element formulations in computation of 3d stress state in elastic shells. In that sense we compare three higher-order shell models: (i) with seven dislacement-like kinematic parameters,

Modeling of kinematic hardening at large biaxial deformations in pearlitic rail steel [PDF]

, 2018
Using an Axial-Torsion testing machine, pearlitic R260 steel specimens are twisted until fracture under different axial loads. A well established framework for finite elastoplasticity with kinematic hardening is used to model the deformation of the ...
