“…The CCI and CCG are the main failure modes for cracked structures at elevated temperatures. [1][2][3] The plates are common components in high-temperature structures, [1][2][3][4][5][6] such as the plates in petrochemical equipments and the plate-type nuclear fuel assemblies in nuclear vessels. In order to ensure the service safety of the plate-type components, it is necessary to accurately evaluate their CCI and CCG life.…”

In order to accurately assess creep crack initiation (CCI) and growth (CCG) life for elevated temperature cracked structures, both out‐of‐plane and in‐plane constraints need to be considered, and the unified creep constraint parameter solutions should be investigated. In this work, the new unified creep constraint parameter Ac values for plate structures with various surface crack sizes subjected to tensile and bending loads have been investigated and obtained using three‐dimensional (3D) finite element (FE) analysis. The effects of material creep properties, crack sizes, loading modes, and plate thickness on the parameter Ac have also been analyzed. The estimation equation of Ac for materials with different creep exponent n has been fitted. The parameter Ac solutions can be used in CCI and CCG life evaluation of the C*‐Ac two‐parameter approach for cracked plates subjected to tensile and bending loads.

“…The plate structures are also often used in high temperature conditions, such as the nuclear fuel assembly and fuel cell electrode plate. [1][2][3][4] For defective plates under high temperature conditions, the initiation and propagation of creep or creep-fatigue cracks are the main failure modes. [16][17][18] It is not appropriate to apply K or J integral to describe the stress-strain field at crack tip region.…”

The plate structures are also often used in high temperature conditions, such as the nuclear fuel assembly and fuel cell electrode plate 1–4 .

“…6 AMCs have an excellent combination of properties such as the light-weight, high stiffness, high creep, and impact resistance that satisfies the requirements of those applications. Al-alloys were heavily used in the construction of some reactor internals and various types of fuel cladding 7 as they had low cross-section for capturing thermal neutrons besides excellent corrosion resistance and thermal conductivity. Commercial pure aluminum (Al-1100) is a very common Al-alloy and is used in the manufacture of railway vehicles, cooking utensils, reflectors, and the lighting industries.…”

Aluminum matrix composites (AMCs) are innovative engineering materials in which a tough reinforcement is included in the aluminum matrix to improve its properties. In the study, MgO (0–4 wt.%) was loaded to Al-1100. The XRD reveals that MgO has a cubic crystal structure, purity of 100 %, and the average crystallite size is 17.4 nm, from Scherer's formula. HR-TEM reflected that MgO displays nanoparticle-like morphology. The microstructural properties of AMCs manifested the intermetallic compounds’ absence, grain refinement, good MgO distribution, and the presence of few porosities. The density measurement confirmed the decrease in the experimental density with increasing MgO while the theoretical density increased. The maximum porosity found is 1.4 % which is accepted in the fabrication of AMCs. The tensile properties revealed that as the strain rate ([Formula: see text]), γ-irradiation dose, and MgO content increases, the fracture stress ([Formula: see text]) increases while the ductility (εΤ) decreases. These three parameters could control the tensile properties of AMCs reinforced with MgO as well. An improvement by 140 % in σf was achieved for AMC with 4 wt.% MgO (at [Formula: see text] = 1.2 × 10−3 s−1, 2 MGy) compared to plain Al-1100 alloy (at [Formula: see text] = 5.4 × 10−5 s−1, 0 Gy). It was suggested that the load transfer from matrix to reinforcement was efficient which directly improves the load-carrying ability of these synthesized AMCs. Several mechanisms such as Orowan strengthening, and dislocation strengthening, were suggested to interpret the tensile properties.
