An excessive thermal load will drive small defects in the cement sheath to grow and tunnel along the length of the well, leading to the failure of zonal isolation function. In this work, we investigate the crack tunneling in cement sheath under steady-state and transient thermal loads. We calculate the energy release rate at tunneling front as a function of the width of tunnel and time. As long as the maximum energy release rate remains below the fracture energy of the cement, tunnels of any size will not form at any time, which provides a conservative failsafe criterion for the cement sheath without requiring the knowledge of crack information. The failsafe criterion predicts that the cement sheath is more prone to cracking under thermal shock, and the thermal constants of cement only have limited effect on the critical condition. This work provides guidelines for cement design and downhole operation conditions to maintain the integrity of cement sheath.</p></div>","PeriodicalId":50892,"journal":{"name":"Acta Mechanica Solida Sinica","volume":"39 8","pages":"1132 - 1143"},"PeriodicalIF":2.6,"publicationDate":"2025-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782117","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 simulations reveal that, when shearing is the dominant mechanism, the CRSS increases with precipitate size, whereas under bypass-dominated conditions, it decreases as precipitate size increases. To interpret and quantitatively predict the DDD simulation outcomes, modified theoretical models are proposed. To address the limitations of the theoretical models, machine learning (ML) techniques are further employed. The ML analysis identifies a strong positive correlation between precipitate volume fraction and CRSS. Precipitate size exhibits a negative correlation with CRSS in bypass-dominated scenarios, but a positive correlation under shearing-dominated conditions. The influence of dislocation type is found to be comparatively minor.

The finite element model is established based on the maximum stress failure criterion, cohesive zone model, and bilinear traction-separation law. The experimental and simulated damage failure modes demonstrate strong consistency. Quasi-static penetration experiments are conducted on hybrid fiber-reinforced polymer (HFRP) laminates with three different ply stacking sequences (alternating and double-interlayer configurations). Comparative analysis of damage failure modes indicates that the [CFRP/BFRP/BFRP/CFRP] (CBBC) sandwich stacking configuration demonstrates superior anti-penetration performance. Based on the CBBC stacking scheme, asymmetric ply-angle configurations are specifically proposed for basalt fiber-reinforced polymer (BFRP) and carbon fiber-reinforced polymer (CFRP), respectively, to investigate the penetration damage mechanism and energy absorption mechanism of the laminates at 0°, 15°, 30°, and 45° antisymmetric ply angles. Notably, the 15° asymmetric ply-angle design significantly enhances the impact strength of HFRP by changing the transfer of interlayer shear stress within the laminates and realizing the stress redistribution mechanism. The synergistic regulation mechanism of dynamic anti-penetration performance of HFRP laminates by laminate stacking sequence and parameterized ply angle configuration is systematically revealed.</p></div>","PeriodicalId":50892,"journal":{"name":"Acta Mechanica Solida Sinica","volume":"39 7","pages":"933 - 947"},"PeriodicalIF":2.6,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148614965","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 elastic constants of the material are inversely characterized by minimizing the difference between the processed kinematic data and its predicted counterpart obtained from the complex-variable method. Once the elastic constants are determined via the inverse approach, the hybrid stress field is evaluated based on fundamental mechanics principles—i.e., equilibrium and compatibility—instead of physically differentiating the kinematic field.

To demonstrate the effectiveness and robustness of the complex-variable method in direct and inverse analyses, several parameters are investigated, such as the number of processed data points, the level of random noise superimposed on the simulated kinematic data, the number of retained terms in the series expansion of the displacement equations, and the form and magnitude of the externally applied load.</p>\u0000 </div>","PeriodicalId":50892,"journal":{"name":"Acta Mechanica Solida Sinica","volume":"39 8","pages":"1079 - 1098"},"PeriodicalIF":2.6,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782888","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 dispersion curves for bulk wave propagating in the ZnO FBAR sensor are derived, and general mode-coupling solutions are constructed by superimposing wave solutions of several eigenmodes along both positive and negative propagation directions.
