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 …

A series of strain-controlled creep-fatigue tests with various dwell times and strain ratios are
carried out on a nickel-based superalloy at 650° C. Aiming at the mechanical understanding …

In this paper, a dual-scale modelling approach is developed to investigate creep-fatigue
behavior and predict crack initiation life for holed structures under multi-axial stress state …

As geotechnical engineering expands to deeper formations, the creep behavior of
surrounding rock becomes more significant. To better understand the creep deformation and …

In the long-term service process, materials and structures will bear fatigue, ageing, and other
degradation behaviours under environmental factors such as temperature, vibration, and …

The experimental results show that the creep properties of the rocks are affected by the
initial damage, and the damage evolution also has a significant impact on the time …

The closed-form solution for Prandtl model implemented into the finite element method is
presented which enables elasto-viscoplastic simulations of engineering materials. A …

Creep and cyclic plasticity are two common mechanical behaviors in engineering, and their
interaction significantly affects the performance and degradation of corresponding …

Multi-axial stress states are common in the most high-temperature components. In this
paper, a ratcheting modified strain energy density exhaustion (RM-SEDE) model is …

Mechanical properties of crazed polymers are the competitive result between damage and
toughening. Firstly, the fractal dimension interval of the planar crazes is proved to be [0, 2) …
