Benefit from the proposed mechanics model, the high-precision strains at the fingertips with printed sensors are detected with a reduction for measurement error from 37% to 7%. Consequently, the grip postures can be adjusted according to the feedback strain to accurately control the pinching forces, which successfully pick up fragile objects without damage.

The <em>G</em> values determined using LEFM coupled with an effective crack length approach have been compared with the <em>J</em>-integral values measured simultaneously using the crack length independent slope-based <em>J-</em>integral methods. It is shown that higher <em>G</em><sub>IIc</sub> values than <em>J</em><sub>IIc</sub> values were measured using ELS specimens, but the <em>G</em><sub>I/IIc</sub> values were in good agreement with the <em>J</em><sub>I/IIc</sub> values measured using FRMM specimens. It is shown (by experimental and numerical investigations) that LEFM became invalid in Mode II due to the occurrence of local damage in the bondline of the specimen close to the clamp. This local damage resulted in erroneously high <em>G</em><sub>IIc</sub> values being measured via LEFM. In contrast, the <em>J</em> method was able to provide accurate and valid toughness values as the contribution of local damage could be excluded through careful selection of the integral contour. Further analysis indicates that, if the local damage was eliminated by adding additional constraint to the specimen at the clamp, then valid values of <em>G</em><sub>IIc</sub> via LEFM could be obtained. The <em>J</em>-integral method in this work provides an alternative tool to determine the fracture toughness of adhesive joints under Mode II loading in case of additional (secondary) damage outside the fracture process zone (FPZ) occurs, which is quite challenging for LEFM methods to separate the energy dissipated in and outside the FPZ.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"192 ","pages":"Article 108777"},"PeriodicalIF":8.1,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
