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 . Navaei. , Siegfried Malang, . Xueren. Wang. ARIES . Project Meeting. Jan. 26. th. ,2011 UCSD. Definition of Creep. 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:. 1)A coil of solder will be suspended from a clamp into a glass.. Boiling water will then be added.. You must visually inspect the coil every 30 seconds for 10 minutes and note any changes.. 2)An aluminium rod will be handed to each pair.. B. H. Mills, and J. D. Rader. G. W.
