Unlike the existing PD coupled multi-physics models, this novel PD model for the first-time accounts for the irradiation-induced behaviors such as densification, swelling, and creep. Also, it captures the Pellet and Cladding Interaction (PCI) under realistic boundary conditions. Furthermore, random critical stretch values with normal distribution within the fuel rods lead to realistic crack pattern of fuel rods during prolonged irradiation. The crack pattern of fuel rods with irradiation is compared with those without irradiation. The results show that the fuel pellet initially shrinks and then expands as burnup rises, while cladding consistently shrinks inward until gap closure, with its compressive state relieved by PCI. Associated with the damage in fuel rods, radial cracks occur during the power rise, while circumferential cracks mainly form during the densification stage, and only few secondary circumferential cracks occur during power ramp-down. The displacement of damaged pellet increases slowly as burnup rises, and the gap closure time is greatly delayed compared with that of an undamaged pellet.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"310 ","pages":"Article 113203"},"PeriodicalIF":3.4,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143153369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed element, derived from the classical four-node Q4 element, incorporates a discrete shear projection method to evaluate transverse shear deformation using precise interpolation techniques. This approach effectively captures the complex mechanical behavior of nanocomposite plates while avoiding the computational complexity associated with higher-order shear deformation models. The developed Q4γ element, based on first-order shear deformation plate theory, features five degrees of freedom per node and maintains inter-element continuity through C⁰ continuity for kinematic variables. Isoparametric coordinates generate elementary stiffness and mass matrices, enhancing the formulation’s accuracy. Notably, the model mitigates shear locking without resorting to sophisticated numerical techniques. Governing equations are derived using the weak form of the variational principle. The mechanical properties of FG-CNTRC plates are modeled to vary gradually across the thickness, accounting for different distribution patterns and CNT volume fractions. The model’s performance is rigorously validated against analytical solutions and established finite element models, demonstrating excellent accuracy without requiring excessive mesh refinement. Comprehensive numerical investigations explore the influence of material and geometric configurations on the free vibration response of FG-CNTRC plates. The Q4γ element proves particularly effective in capturing both in-plane and out-of-plane responses in advanced composite structures. Results indicate that optimized reinforcement distribution patterns can significantly enhance computational efficiency. This research provides a valuable tool for designing and optimizing CNT-reinforced nanocomposite structures, with potential applications in aerospace and automotive industries where multiphysics environmental impacts are critical.

An experimental isolation of these two influencing factors is challenging, especially at large plastic strains, since a variation of the Lode parameter is usually accompanied by a variation in the triaxiality. In this study, forward rod extrusion and forward hollow extrusion are utilized to induce Lode parameters (<em>L</em>) of −1 and 0, respectively, while keeping the triaxiality and the plastic equivalent strain the same in both processes. For the triaxiality this is accomplished by superposing hydrostatic pressure by a counterpunch during forward rod extrusion. This allows for the first time, to the author’s knowledge, to experimentally study the isolated effect of the Lode parameter on void evolution at large plastic strains, and the resulting effects on product performance like impact toughness. Mass density measurements and scanning electron microscopy (SEM) on extruded samples of the case hardening steel 16MnCrS5 reveal an increased damage evolution under <em>L</em> = 0 as compared to <em>L</em> = −1. The SEM investigations show a distinct switch in void nucleation mechanisms from cracking of manganese sulphide inclusions for <em>L</em> = −1 to cracking and debonding of inclusions and surrounding matrix for <em>L</em> = 0. The debonding occurs in a preferred direction, leading to anisotropic void area fractions. The locations of inclusion-matrix-debonding are verified by evaluation of interface stresses between matrix and inclusion in representative volume element simulations. While the impact toughness of specimens extracted along different orientations is consistently different, this cannot be conclusively attributed only to the corresponding microscopic damage anisotropy.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"310 ","pages":"Article 113205"},"PeriodicalIF":3.4,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143153365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed model is capable of handling arbitrary lengths of bonded and non-bonded segments and the large deformation of the film. In the process of film peeling under discontinuous adhesion, peeling force exhibits repetitive fluctuations. The peak signifies the initiation of the peeling front transitioning into the non-bonded segment, while the trough represents the delamination front advancing into the bonded segment. These fluctuations stem from the transfer and redistribution of bending energy in the film: energy release occurs as the peeling front enters the non-bonded segment, while re-accumulation takes place as it enters the bonded segment, resulting in increased peeling force. Additionally, we discuss the periodic discontinuous bonding, exploring different cases of bonding length proportions and period lengths.
