ULTIMATE SHEAR OF BEAMS STRENGTHENED WITH CFRP SHEETS

, 1999
The role of externally applied CFRP sheets in the evaluation of the shear strength of a reinforced concrete element is analyzed. With regard to this an analytical model is developed. It represents an extension of an existing model for the limit analysis of thin-webbed reinforced concrete beams falling in shear.

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

Application of Brittle Materials to Strengthen Masonry [PDF]

, 2008
Fibre Reinforced Polymer Strengthening (FRP) has become a popular method for retrofitting masonry structures. It is easily applied by attaching bonding either dry fibre mats or pre-formed plates to an existing structure.

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.

Masonry wall panels retrofitted with thermal-insulating GFRP-reinforced jacketing [PDF]

, 2015
Today there is a need to provide thermally efficient walls, while at the same time to increase the mechanical properties of old unreinforced masonry walls that will not require large amounts of energy in the retrofitting or deconstruction processes.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging
