Ratchet limits for a crack in a welded pipe subjected to a cyclic temperature load an a constant mechanical load [PDF]

, 2011
This paper presents the ratchet limit analysis of a pipe with a symmetric crack in a mismatched weld by using the extended Linear Matching Method (LMM). Two loading conditions are considered: i) a cyclic temperature load and a constant internal pressure;

Dissipation of Energy and Generation of Pore Pressure in Load-Controlled and Displacement-Controlled Cyclic Tests

Geotechnics
The amount of energy dissipated in the soil during cyclic loading controls the amount of pore pressure generated under that loading. Because of this, the normalized dissipated energy per unit volume is the basis for both pore pressure generation models ...

Evolution of contact resistance and coupling loss in prototype ITER PF NbTi conductors under transverse cyclic load [PDF]

, 2003
Cyclic energizing of a magnet coil with Cable in Conduit Conductors (CICC), as for fusion applications, results in an anomalous change of the interstrand contact resistance (R/sub c/) and coupling loss (n/spl tau/) due to the alternating transverse ...
