Bond performance of CFRP strengthened steel members subjected to axial compression

, 2013
This paper focuses on the use of externally bonded Carbon Fiber Reinforced Polymer (CFRP) materials to strengthen steel plates subjected to compression. A fully slender steel section was selected in this test programme. CFRP strengthened steel plates and

Gas path diagnostics for compressors [PDF]

, 2012
The use and application of compressors cannot be overemphasized in the aeronautical and oil & gas industries. Yet research works in sufficient depth has not been conducted previously to analyze their actual behaviour under degraded or even new conditions

Performance of tri-tubular conical energy absorber under axial compression

Journal of Mechanical Engineering and Sciences
Quasi static axial compression loading on tri-tubular cone (TC) has been carried out using LS-DYNA finite element analysis method. Tri-tubular cones of three arrangements; the first arrangement (model TC-1) consists of cone heights of 50 mm, 75 mm and ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Performance Study on Axial Compression of CFRP-Strengthened Concrete Columns

Hans Journal of Civil Engineering, 2015
通过对6个混凝土柱的静力加载试验，本文研究了碳纤维布加固对不同截面混凝土柱的力学性能的影响，分析了碳纤维布粘贴层数及短柱截面类型对碳纤维布加固效果的具体影响。结果表明：碳纤维布可明显提高混凝土柱的刚度和极限承载力，减小柱的竖向位移，减小柱的横向应变和纵向应变；当碳纤维布粘贴层数为两层时，其影响程度比粘贴一层时更为显著，但其提高程度不与加固面积成正比；碳纤维布加固对混凝土圆柱极限承载力和刚度的提高优于对混凝土方柱的提高。 Through the static load test of six CFRP reinforced concrete columns, the paper studies the CFRP reinforced concrete columns with different ...

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

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 ...

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,

Axial Compression Performance of L-Shaped Partially Encased Steel–Concrete Composite Stub Columns

The L-shaped partially encased steel–concrete composite (PEC) stub column, composed of profile steel, concrete, and transverse links, tends to occupy less space than the rectangle-shaped PEC column when used as side or corner columns. In this study,
