Dual-Arm Coordinated Control Strategy Based on Modified Sliding Mode Impedance Controller

Sensors, 2021
To meet the high-accuracy position/force control requirements of dual-arm robots for handling a target object, a control algorithm for dual-arm robots based on the modified sliding mode impedance controller MSMIC(tanh) is proposed. First, the combinative

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Predicting implant UHMWPE wear in-silico: A robust, adaptable computational-numerical framework for future theoretical models

, 2011
Computational methods for the pre-clinical wear prediction for devices such as hip, knee or spinal implants are valuable both to industry and academia. Archard’s wear model laid the basis for the first generation of theoretical wear estimation algorithms,

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Volume changes of concrete in interaction with sliding joint

Modern Building Materials, Structures and Techniques (MBMST), 2019
The paper describes volume changes of cement plain concrete and steel fiber reinforced concrete with strength class C 30/37 in interaction with sliding joints. In the research experiment was performed large-dimensional specimens, on which volume changes were measured using string strain gauges.

The First Knowledge of Electronic Heating of Sliding Joint

Advances in Engineering Research, 2015
Sliding joints are very often used to reduce shear stress in foundations if this shear stress arises. This paper explains and demonstrates reasons for application of sliding joint in to foundation structures and its basic function. The laboratory tests of modern sliding joint are introduced too.
