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. Finite element analyses were performed for a C(T) specimen under constant loading condition for elastic-plastic-creeping materials. In modeling C(T) geometry, an interface was employed along the crack plane which simulated the interface between weld and base metals. The <TEX>$$C_t$$</TEX> versus time relations were obtained under various creep constant combinations and plastic constant combinations for weld and base metals, respectively. A unified <TEX>$$C_t$$</TEX> versus time curve is obtained by normalizing <TEX>$$C_t$$</TEX> with C* and t with <TEX>$$t_T$$</TEX> for all the cases of material constant variations.
