Reinforcement detailing rules describe the shape, geometrical dimensions, and amount of steel to be placed in reinforced concrete structures. They allow for simple and fast designs, account for several effects neglected in the design, ensure a satisfactory ...
A coupled hydromechanical granular model aimed at predicting hot tear formation and stress-strain behavior in metallic alloys during solidification is applied to the semicontinuous direct chill casting of aluminum alloy round billets. This granular model c ...
Thermally-induced residual stresses, generated during the industrial Direct Chill casting process of aluminum alloys, can cause both significant safety concerns as well as the formation of defects during down-stream processing. Although these thermally ind ...
Existing shear-cracked structures need to be reliably verified in order to avoid redundant interventions. Code provisions often raise shear safety and/or fatigue life concerns of the reinforcement subjected to stress concentrations due to cyclic dowel acti ...
Reinforced concrete walls are commonly used to resist the lateral loading induced by wind and earthquake actions. While most walls include two vertical reinforcement layers, some regions of the world construct slender, non-rectangular concrete walls with a ...
The rigid body motion of the workpieces and their elastic-plastic deformations induced during high speed milling of thin-walled parts are the main root causes of part geometrical and dimensional variabilities; these are governed mainly from the choice of p ...
A study of the microstructural evolution of Zircaloy-4 (Zy-4) during hot extrusion has been performed on a small scale device mounted on a standard MTS machine. Before extrusion the billets present a Wind-manstätten lamellar microstructure. Additional data ...
Electro Discharge Machining (EDM) is an attractive subtractive method for complex 3d structurization of hard and very hard conductive and semi-conductive materials. The machining capabilities of a material do not depend on its hardness but on its electric ...
Hot tearing is one of the most severe defects observed in castings, e.g. in billets or sheet ingots of aluminum alloys produced by DC casting. It is due to both tensile strains and a lack of interdendritic feeding in the mushy zone. In order to predict thi ...
The design of dies for the light-metal extrusion process is based primarily on the experience of the die designer. The performance of the die is only known after the die is manufactured and tested on the extrusion press. It is still a major challenge for t ...
