Then, the pushing device 15 is rotated clockwise by a hydraulic motor 23. Downward force is applied to the pusher die 12, and the tube 14 is pressed in the direction in which tensile stress generated at the inside is reduced. On the other hand, the pushing device 15 moves engaging with...
The effects of initial ovality, residual stress, strain-hardening, yield anisotropy and loading paths are included in the analysis. The analysis procedure is validated through a systematic comparison with excellent experiments published. Sensitivity studies on the factors affecting tube collapse have been...
One of the processes during the design of a steel tube umbilical is the determination of the minimum allowable bending radius of the umbilical. This bending radius is calculated by determining the stress that is experienced by the umbilical during different phases of its life and also under variou...

And with the analytical model, simulation model and experimental bending results, the forming characteristics of bent tube with small bending radii based on the spherical connection structure were investigated. The main results show that the equivalent stress, displacement of the strain neutral layer (...
申请(专利权)人: TUBE BENDING COCEPTS, INC.发明人:MG Sr.,JA Siebert 被引量: 9 摘要: A tube bending mandrel is provided, which is designed to avoid stress, fracture, and disassembly caused by forces exerted while a tube is bent. The mandrel includes mandrel links with a ball end, neck...
The threshold stress for crack-healing was defined as the maximum stress below which the crack-healed specimens recovered their bending strength and below which most specimens fractured outside the crack-healed zone. From: Handbook of Smart Coatings for Materials Protection, 2014 ...
