Application of an elastoplastic model to predict behaviors of Concrete-Faced Rock-fill Dam under complex loading conditions

open access: yesJournal of Civil Engineering and Management, 2015
In this research, a simplified rotational kinematic hardening model with the concept of sub-loading was used to predict behaviors of Concrete-Faced Rock-fill Dam under complex loading conditions.

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter

open access: yesAdvanced Robotics Research, EarlyView.
A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.

Identification of Combined Isotropic–Kinematic Hardening Parameters from Reverse Bending Tests Using Recurrent Neural Networks

open access: yesMetals
Accurate identification of constitutive parameters is essential for reliable finite element simulations of sheet metal forming processes. Conventional inverse identification techniques, such as Finite Element Model Updating (FEMU), generally require ...

Accumulation of Pore Pressure in a Soft Clay Seabed around a Suction Anchor Subjected to Cyclic Loads

open access: yesJournal of Marine Science and Engineering, 2019
A suction anchor is an appealing anchoring solution for floating production. However, the possible effects of residual pore pressure can be rarely found any report so far in term of the research and design.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

open access: yesAdvanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Wrinkling prediction in deep drawing metal forming : kinematic hardening model versus mixed hardening model [PDF]

open access: yes, 2017
One of the common major defects in deep drawing sheet metal forming is wrinkling. It is known as the formation of uneven height at the top rim of a drawn part due to multi-axial stresses acted on the blank material during the deformation process ...

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.
