PPT-Fracture and Creep in an All-Tungsten Divertor for ARIES

Jake Blanchard University of Wisconsin Madison August 2012 Introduction The ARIES Project is exploring the feasibility of using tungsten as a structural material for plasmafacing components. Dara .

Creep is a rate dependent material nonlinearity in which the material continues to deform under a constant load (ANSYS). Creep is highly time dependent and it displays its effects over a long time. Creep has 3 stages:. Domestic Production and UseA tungsten mine in California produced concentrates in 2013. Approximately eight companies in the United States processed tungsten concentrates, ammonium paratungstate, tun N. . Fedorczak. , . P. . Monier-Garbet. , T. Pütterich, S. . . Brezinsek, . P. . .
