In this study, a dual-scale numerical procedure is developed to reveal the creep-fatigue
damage mechanisms and estimate the crack initiation life for notched structures made of …

Fatigue damage is a concern in the engineering applications particularly for metal
structures. The design phase of a structure considers factors that can prevent or delay the …

The elucidation of creep-fatigue damage mechanisms is still controversial for high-
temperature structures after surface strengthening treatments, which serves as a critical …

In this paper, a new numerical procedure based on a cycle-by-cycle analysis has been
constructed for creep-fatigue behavior and life prediction of high-temperature structures …

In this work, an extended finite element based fully implicit algorithm is proposed to predict
the creep deformation and creep crack growth in elasto-plastic-creeping solids. The effect of …

Plane strain finite element calculations of mode I crack growth are carried out under small
scale creep conditions with an imposed stress intensity factor that is a prescribed cyclic …

This paper presents a physically-based microstructural model for creep rupture at 600 C for
Grade 91 steel. The model includes constitutive equations that reflect various observed …

In this paper, the creep-fatigue behavior of directionally solidified superalloy DZ125 has
been investigated by stress-controlled experiments at high temperatures with different dwell …

Creep–fatigue crack growth (CFCG) behavior, fracture mechanism, and microstructural
evolution of G115 steel under different hold times and initial stress intensity factor ranges …

For improving fracture resistance, metal Cu nanoparticles were used as additive in Ag/SnO 2
contact materials. The fracture behaviors and mechanical properties of the Ag-8wt% SnO 2 …
