The utilization of variable-stiffness composites (VSC) with curvilinear fibers is gaining increasing attention for buckling design of cylindrical shells. Given their substantially greater complexity in both fiber orientation distribution and thickness variation compared to conventional straight-fiber composites, nonlinear buckling analysis of VSC structure via the finite element method incurs considerably higher computational demands. To enhance the computational efficiency, an IGA-based framework aiming at buckling prediction of VSC cylindrical shells with non-uniform thickness is established in this paper for the first time. To address the practical limitations of existing IGA surface reconstruction methods, we propose a novel cylindrical shell modeling approach that integrates NURBS surface fitting with the Inverse Distance Weighting (IDW) method, enabling effective reconstruction of VSC cylindrical shells. Isogeometric shell elements based on 7-parameter solid shell theory incorporating artificial damping are used for nonlinear buckling analysis of VSC shell structures. Four representative case studies validate the accuracy and computational efficiency of the proposed element and framework. Results demonstrate that the IGA elements consistently achieve significantly higher computational efficiency than conventional shell elements.

Preload measurement and tensile tests on individual swage-locking pins were additionally conducted to evaluate their preload stability and tensile resistance. Finite-element (FE) models for both T-stubs and swage-locking pins were developed and validated against the experimental data. An extended parametric study was performed to investigate the effect of key parameters—pin pitch, preload, equivalent segment length, and pin diameter—on the structural behaviour of T-stubs. The existing design methods for predicting the resistance of SS T-stubs, including the design provisions in EN 1993–1–8 (EC3) and the Continuous Strength Method (CSM), were evaluated. The results show that EC3 significantly underestimates the ultimate resistance of this connection. The CSM is a deformation-based framework that accounts for stainless-steel strain hardening and provides a higher flange plastic resistance <em>M</em><sub>f,Rd</sub>. The results indicate that the CSM improves the prediction accuracy of ultimate resistance while remaining conservative. Therefore, a new CSM-based design method is proposed for stainless-steel T-stubs connected by swage-locking pins.

The ballistic responses - specifically damage modes, ballistic limits, and specific energy absorption - of 3D orthogonal and angle interlock woven fabrics were experimentally investigated, with a focus on the influence of areal density. Fabric areal density was systematically modified by modulating the fiber bundle count and the interlacing layer number. A primary-yarn-oriented meso‑macro hybrid-scale ballistic impact numerical model was established and verified for large-sized 3D woven fabrics with respect to ballistic limit and impact process. The numerical analysis focused on detailing the penetration characteristics, stress wave propagation, component yarn deformation and energy distribution within the 3D orthogonal and angle interlock woven fabrics under ballistic impact. The results indicated that reducing the yarn’s fiber bundles count and increasing the layer count could improve the ballistic limit of 3D woven fabrics.

Therefore, understanding of their multiaxial cyclic mechanical behavior is essential to ensure structural integrity. This study investigates the multiaxial fatigue behavior of Q345E tube-to-plate welded joints under both constant-amplitude and three-step variable loading paths. The effects of equivalent stress amplitude, stress phase difference, and loading sequence were examined. The results indicate that under three-step variable loading, the cumulative fatigue damage is significantly influenced by the loading sequence, which is primarily controlled by the phase difference between loading steps. Furthermore, the stiffness in a subsequent loading step is governed by whether its phase difference exceeds that of the preceding step. Scanning electron microscopy (SEM) and 3D topography analysis reveal that the phase difference between the second and third loading steps determines both the microscopic fracture morphology and surface roughness. Moreover, the surface roughness increases significantly with the degree of non-proportionality induced by these two loading steps. Among the Smith–Watson–Topper (SWT), Fatemi–Socie (FS), Modified-Kandil–Brown–Miller (MKBM), and Chen–Dong–Huang–Liu (CDHL) critical plane models, the MKBM model achieved the highest accuracy in predicting fatigue life under constant-amplitude loading, with 87.5 % of predictions falling within a scatter band of 1.25 and 96.3 % of predictions falling within a scatter band of 1.5.
