Influence of the constitutive flow law in FEM simulation of the Radial forging process [PDF]
, 2013 Radial forging is a widely used forming process for manufacturing hollow products in transport industry. As the deformation of the workpiece, during the process, is a consequence of a large number of high-speed strokes, the Johnson-Cook constitutive law (

Use of Long Radial Sheaths for Radial Artery Spasm in Neurointerventions
, 2021 One of the challenges of the radial approach is radial artery spasm. Because of the smaller caliber, the guide catheters can cause significant spasm that can complicate the procedure or even preclude it.

Radial Variation of Magnetic Properties in Submarine Pillow Basalt
, 1975 A detailed study has been made of the magnetic properties of four pillow lavas of differing ages from the Mid-Atlantic Ridge crest at 45°N. The pillows show radial variations in grain size and concentration of titanomagnetite due to the initial cooling ...
