Prior to the steady state, the peeling force typically increases in the initial stage and then decreases nonlinearly in the transition stage. However, existing mechanics models rarely capture the effects of the film’s tensile stiffness and peeling angle on these two stages, particularly the initial peeling stiffness and peak peeling force. Though extending a recent model (<span><span>Yuan et al., 2024</span></span>) by accurately incorporating the film’s in-plane deformation and arbitrary peeling angle, this work establishes a comprehensive large-deformation model using the energy-variational method. The proposed model effectively predicts the entire peeling process across different peeling angles and is validated by molecular dynamics simulations. For relatively large peeling angle, the film’s tensile stiffness exhibits minor effect on the peeling behavior. The influences of the peeling angle on the peeling process, peeling stiffness, and peak peeling force are analyzed in detail. Through dimensional analysis, an explicit scaling relation for the peak peeling force is derived, accounting for system parameters such as peeling angle, film stiffness, structural parameters, and interfacial properties.

A double helical structure has been developed to introduce large axial twistable capability, where thin-walled cured composite strips with a longitudinal curvature were prestressed or flattened to be employed as shape-changing units, and then assembled by using rigid spokes, pins, or webs; however, its twisting performance would be susceptible to thermal effects, and affected by the curvature variations induced by flattening and assembling of the precured curved strips. Here, we proposed a novel double helical structural design, where thin-walled curved tapes with transverse curvature were applied as the shape-changing units without prestressing. The double helical structures were produced and investigated with isotropic transverse curved tapes, orthotropic flat strips, as well as orthotropic transverse curved tapes, in order to reveal its geometric curvature effects-induced twisting mechanics. An inextensible shell model was formulated to analyse the shape-changing process, and expose the regulating mechanisms on structural stability. Experiments and finite element analysis were carried out to investigate the material and geometric curvature dependencies. It is found that the material orthotropy contributes to the bistability of the helical structure; geometric curvature promotes the stiffness and shape-changing stability of the double helix. The twisting mechanisms were then concluded in detail. These findings are expected to facilitate torsional structural design and application of deployable composite structures for aerospace engineering.</div></div>","PeriodicalId":14311,"journal":{"name":"International Journal of Solids and Structures","volume":"315 ","pages":"Article 113369"},"PeriodicalIF":3.4,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808724","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}
