They must fulfill premises of structural integrity, especially in offshore environment, which imposes extreme pressure and temperature conditions to the well structure. Among the loads undergone by casing tubes, such as axial force, internal pressure, and external pressure, this latter stands out, leading to a failure mode known as collapse. Imperfections associated with casing tubular manufacturing processes, such as cross-sectional eccentricity and ovality, and the residual stress of the steel, are expected to influence the collapse mechanism. Moreover, the inner wall of the casing experiences wear, predominantly caused by intense contact with the drill string during the well construction. These imperfections can lead to a significant reduction in the collapse strength, especially in thin-walled tubes, whose failure mechanism is associated with geometric instability caused by high cross-sectional slenderness. This paper presents a 2-D finite element analysis of the collapse strength of worn tubulars with initial imperfections, via software Abaqus. The plane strain hypothesis is assumed, in a physically and geometrically nonlinear approach. The mechanical response of steel is described by the elastoplastic model with nonlinear hardening provided by ASME VIII - div. 2 (2019), and the Riks’ method is employed to evaluate the nonlinear behavior. The consideration of internal wear is made by removing material from the inner wall, as a groove shape. Model validation is performed using experimental results from the literature. A parametric study is carried out to assess the influence of slenderness, wear depth, steel grade, tool joint diameter, and initial imperfections (ovality and eccentricity) in the residual collapse strength. The results indicate the wear groove depth as the most influential variable for the reduction in collapse strength. Other parameters also play a role in the determination of collapse strength and may be relevant for casing integrity analysis. These conclusions are consistent with and converge with findings reported in previous studies in the literature. Finally, a case study of a critical region of a well, which data were obtained through an ultrasonic logging tool, is presented. Different types of inspection data and data application approaches (inner radius-based and thickness-based) are evaluated, with the latter proving to be more reliable due to its lower sensitivity to measurement noise. A severe derating of the collapse pressure is observed, with reductions ranging from approximately 14% to 50%, even though the maximum wear depth observed in this case study is limited to 13%. This variability highlights the importance of carefully interpreting inspection data, since at the time of inspection the cross-section may be significantly deformed due to in-situ subsurface well condi","PeriodicalId":49846,"journal":{"name":"Mechanics Research Communications","volume":"153 ","pages":"Article 104635"},"PeriodicalIF":2.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finite element analyses were conducted to evaluate the individual and combined effects of two key parameters: the number of auxetic core layers and the percentage of continuous carbon fibers (CCF) embedded within the auxetic geometry. Parametric simulations revealed that CFRP wraps significantly improve compressive strength, while auxetic cores, especially those with higher CCF content, enhance both strength and strain capacity. Hybrid configurations integrating CFRP wraps with auxetic cores outperformed both standalone systems. Notably, the configuration consisting of a re-entrant auxetic core sandwiched between two inner and two outer CFRP layers achieved a 221 % increase in compressive strength and an 80 % increase in strain capacity compared to unconfined concrete, along with a 50 % improvement in strain capacity over a four-layer CFRP-wrapped specimen. While compressive strength gains plateaued at higher CFRP wrap densities, strain capacity continued to improve with auxetic core inclusion. This enhancement is attributed to the auxetic core’s unique lateral contraction behavior under axial load, which intensifies confinement pressure and delays tensile cracking. When combined with CFRP, the auxetic core acts as an adaptive interlayer that maintains continuous contact with concrete substrate, mitigating debonding and promoting more effective stress transfer. These findings demonstrate the effectiveness of auxetic–CFRP hybrid confinement in enhancing both strength and ductility, offering a promising approach for the development of resilient, damage-tolerant concrete systems for structural applications.</div></div>","PeriodicalId":49846,"journal":{"name":"Mechanics Research Communications","volume":"153 ","pages":"Article 104658"},"PeriodicalIF":2.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the mechanical response of AM 316L produced via Laser Powder Bed Fusion (L-PBF) is investigated under uniaxial tension and torsion loadings. First, an inverse FEMU-assisted identification procedure is adopted to identify the material flow curve under the hypothesis of J₂ plasticity. Experiments put into evidence the remarkable strength-differential (SD) effect, being the predominant feature of the macroscopic response of AM 316L L-PBF. Next, the isotropic yield function proposed by Cazacu and Barlat in 2004, expressed in terms of both invariants of the deviatoric stress tensor, with a single unknown parameter governing the SD effect, is used to model the observed experimental features. The predictive capability of the modelling strategy is validated by accurately reproducing the material response under tensile and torsional loading. Furthermore, predictions for loading paths not included in the identification procedure, namely uniaxial compression and combined axial-torsion loadings, are presented and discussed.</div></div>","PeriodicalId":49846,"journal":{"name":"Mechanics Research Communications","volume":"153 ","pages":"Article 104660"},"PeriodicalIF":2.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An experimental campaign was carried out to characterize the elastic properties of the examined stabilized soil, including Young’s modulus and Poisson’s ratio, through compression tests on cylindrical specimens. These experimentally measured properties were subsequently employed to inform both analytical modeling and finite element simulations aimed at predicting the dynamic behavior of the metaconcrete. Dispersion analyses based on Bloch–Floquet theory were performed on a representative unit cell to identify polarization-selective bandgaps associated with local resonance phenomena. The results reveal the presence of a well-defined longitudinal bandgap in the frequency range approximately between 6.5 and 7.5 kHz. A strong agreement is observed between analytical predictions and FEM-based dispersion curves, confirming the robustness of the adopted multiscale modeling framework. The numerical results further highlight the role of local resonance in promoting energy localization within the compliant coating, leading to a marked reduction in longitudinal wave propagation. Overall, the findings demonstrate that stabilized contaminated soils, when properly encapsulated, can be effectively repurposed as resonant inclusions in metaconcrete, combining environmental sustainability with advanced wave attenuation capabilities.
