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 ...

Study of Stress and Deformation of High Concrete-Face Rockfill Dam on Steep Slope in Narrow Valley

Renmin Zhujiang, 2022
At present,in the finite-element stress and strain calculation of rockfill dams,fixed support is mostly adopted to simulate the connection between the rockfill at the bank slope and the slope.As for a concrete-face rockfill dam (CFRD) in the steep slope ...

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Optimum Winding Tension and Nip-load into Wound Webs for Protecting Wrinkles and Slippage

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
This paper describes the novel optimization method of wind-up tension to prevent wound roll defects, mainly star defect (wrinkling) and telescoping (slippage), based on the optimum design technique.

PERFORMANCE OF CORN SOWING IN FERTILIZATION SYSTEM AND INTERCROPPING [PDF]

Engenharia Agrícola, 2018
The performance of the tractor-seeder can be influenced by factors related to the seeder, as loads and crop. The aim of the present study was to evaluate the performance of tractor-seeder at sowing in the corn crop in function of the fertilizer systems ...

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Global Sliding Mode Fault-Tolerant Control for Nonholonomic Wheeled Robots: Ensuring Prescribed Performance in the Presence of Faults and Slippage

IEEE Access
This paper proposes a global integral sliding mode control (GISMC) scheme integrated with an improved disturbance observer (IDO) for robust trajectory tracking of nonholonomic wheeled mobile robots under uncertainties, disturbances, wheel slippage, and ...

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.

Power circulation in driveline system when the wheels of tractor and trailer are driven

Transport, 2013
In off-road “tractor–trailer” vehicle combinations, the trailer can be equipped with one or more driving wheels. The distinguishing feature of vehicles with two or more driving axles is distribution of total power between the driving wheels.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
