However, the bending forming of medium-thick plates is prone to produce crack defects. In this paper, an extended study on crack prediction for bending forming of medium-thick plates is carried out. An improved theoretical crack prediction model considering the neutral layer offset is proposed, aiming to improve the bending crack prediction accuracy of medium-thick plates. The improved Lemaitre ductile fracture criterion integrates the effect of large plastic strain accumulation on damage and investigates the effect of neutral layer offset on strain. With 7075-T6 aluminum alloy as the object, verified by theoretical calculation, DEFORM finite element simulation and macro–micro experiments, the neutral layer offset is 0.6–0.7 mm when cracks initiate. The Lemaitre ductile fracture criterion threshold, <i>C</i>, at the time of experimental (<i>C</i> = 11.46) is compared with theoretically ( <i>C</i> = 11.9), and its relative error is 3.6%. The influence of the neutral layer offset on the accuracy of strain and crack prediction was verified. This criterion effectively improves crack prediction accuracy, provides theoretical support for optimizing the bending process of high-strength aluminum alloy medium-thick plates in marine engineering and aerospace fields.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 3","pages":"2489 - 2502"},"PeriodicalIF":2.3,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147337960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The successful formation of crystalline ZnO NPs was confirmed by XRD, UV-Vis, ATR-FTIR, zeta potential, and TEM analyses, revealing highly stable nanoparticles with an average size of 17.3 nm and a bandgap of 3.42 eV. The biosynthesized ZnO NPs were highly effective in removing the antibiotic ceftriaxone from aqueous solution. Adsorption followed the Langmuir isotherm and pseudo-second-order kinetics, achieving a maximum capacity of 154.5 mg/g via a spontaneous, endothermic physisorption process. SEM images showed that the sponge-like morphology of the nanoparticles facilitated drug loading, with particle size increasing noticeably after ceftriaxone adsorption. Both bare ZnO NPs and ceftriaxone-loaded nanoparticles displayed strong antibacterial activity against <i>Escherichia coli</i> and <i>Bacillus subtilis</i>. Moreover, they exhibited promising anticancer properties against human colorectal (Caco-2) and breast (MCF-7) cancer cell lines, with IC<sub>50</sub> values of 12.5 <i>µ</i>g/mL and 22.4 <i>µ</i>g/mL, respectively. These findings demonstrate that witch hazel-mediated ZnO nanoparticles offer an environmentally benign, multifunctional nanoplatform that combines efficient antibiotic removal with potent antibacterial and anticancer effects, making them attractive candidates for biomedical and environmental applications.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 5","pages":"4301 - 4324"},"PeriodicalIF":2.3,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147755979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
