In the realm of prognosticating remaining useful life (RUL) pivotal components, such as aircraft engines, a prevalent challenge persists where available historical data often proves insufficient. This insufficiency engenders obstacles impediments in performance degradation feature extraction, inadequacies capturing temporal relationships comprehensively, and diminished predictive accuracy. To address this issue, 1D CNN-GRU prediction model for few-shot conditions is proposed paper. pursuit...
Small punch test is applied to estimate mechanical properties and damage evolution by a miniature specimen. Combining small inverse finite element, the elastoplastic parameters in Hollomon model Gurson-Tvergaard-Needleman (GTN) were identified undamaged damaged stages of load-displacement curve. Then, whole stress-strain curve 316L austenitic stainless steel was constructed based on element simulation tensile specimen considering GTN model. To validate curve, standard performed as control...
The effect of the addition alkali earth element Ca on microstructure and mechanical properties extruded AZ91-0.4Ce-xCa (x = 0, 0.4, 0.8, 1.2 wt.%) alloys was studied by using scanning electron microscopy, transmission tensile tests. results showed that could significantly refine second phase grain size AZ91-0.4Ce alloy. refinement most obvious when 0.8 wt.% added, recrystallized 4.75 μm after extrusion. resulted in formation a spherical Al2Ca phase, which effectively suppressed precipitation...
Determining tensile properties from small punch test is being pursued actively in the nuclear industry due to limited volume of material such tests use compared with standard which can be critical when considering active or development samples. One crucial challenges harnessing full potential this technique formulating methodologies correlate specimen's deflection equivalent uniaxial properties. Existing approaches for correlation rely on obtained a single point specimen, used empirical...
The effect of pre-strain on tensile behaviour 316L austenitic stainless steel was investigated, focusing strain rate sensitivity, temperature sensitivity and hardening. Experimental data showed that hardening were weakening with pre-strain. Meanwhile, the variation microstructure observed by optical microscopy, scanning electronic microscopy X-ray diffraction. Then, mechanical properties pre-strained material correlated increase in dislocation density twinning Finally, an improved...
The stress state has an important effect on the deformation and failure of metals. While states axisymmetric notched bars specimens are studied in literature, studies flat metal specimen with inclined notch very limited is not clearly characterized them. In this paper, digital image correlation finite element simulations used to study distribution strain state, that triaxiality Lode angle parameter. Flat was tested extract full field evolution calculate parameters at three locations: centre,...
