This paper presents an enhanced neural network-bootstrap particle filtering algorithm to
construct the complex relationship between the normalized strain relaxation indicators and …

In many fields such as aerospace, petrochemical and energy power, the contradiction
between the need for long-life and high-reliability of critical mechanical equipment and their …

Utilizing vortex-induced vibration piezoelectric energy harvesters (VPEHs) to capture wind
energy from the environment to power sensors is a prospective technique. Most of the …

Continuous damage mechanics (CDM) is based on the theories of continuous medium
mechanics and continuous medium thermodynamics, which considers damage is an …

High-strength lockbolts have been widely applied in large-scale structures, such as wind
turbine supporting structures, due to their excellent anti-lose and fatigue resistance …

Isothermal low-cycle fatigue (LCF) tests on heat-resistant QTRSi4Mo1 cast iron were carried
out at 500 and 760° C. The results showed that the cast iron exhibited initial cyclic hardening …

To investigate the low cycle fatigue (LCF) performance and damage behaviours of marine
high strength steels (HSSs), experimental analysis and constitutive modelling are carried out …

Laser-powder bed fusion (L-PBF) is a popular additive manufacturing method for fabricating
metal parts with complex geometries. However, one of the primary setbacks lies in the …

The integrity of the nuclear reactor components must be guaranteed under operating and
emergency conditions at all times. All possible degradation mechanisms should be …
