bibo:abstract
  • In this study, behavior of <TEX>$$C_t$$</TEX> which is a well-known fracture parameter characterizing creep crack growth rate, is investigated for weld interface cracks of 1Cr-0.5Mo steel. Finite element analysis were performed for C(T) specimen under constant loading condition for elastic-creeping materials. In modeling C(T) geometry, an interface was employed along the crack plane which simulated the interface between weld and matrix metals. <TEX>$$C_t$$</TEX> versus time relations were obtained under various creep constant combinations for weld and matrix metals. The obtained <TEX>$$C_t$$</TEX> versus time curves were normalized by a steady state <TEX>$$C_t$$</TEX> value, (<TEX>$$C_t$$</TEX><TEX>$$)_{ss}$$</TEX>, (C* for homogeneous specimen) and a transition time <TEX>$$t_T$$</TEX>. A unified <TEX>$$C_t$$</TEX> versus time curve were obtained. Application of this unified curve to crack growth life calculation is discussed. (rdf:langString) (en)
