Summary: This study investigates the cross-sectional deformation of piezoelectric cantilever-actuators considering both anticlastic and electromechanical bending effects. The Searle parameter is found to play a key role in characterizing the shape of the cross-section. A load scaling rule provides a criterion for fixed cross-section deflection for different actuator widths, maintaining the Searle parameter unchanged.

Summary: This article presents an algorithm for three-dimensional shape reconstruction based on strain measurements, which is suitable for large deformation of flexible wing-like structures. By using recursion relations to determine the position of material points, the method demonstrates high accuracy and capability in reconstructing deformed shapes. Furthermore, the study results show the significant impact of warping effect on predicting twist angle.

Summary: This paper presents an enhanced neural network-bootstrap particle filtering algorithm to construct the complex relationship between normalized strain relaxation indicators and crack front profiles. The metamodel of normalized strain relaxation indicators and crack front profiles in welded plate joints is built using optimal regression neural network and finite element analysis. New crack-related weight functions are proposed to overcome uncertainties caused by limited strain measurement, crack measurement, and different non-destructive techniques. The intelligent crack sizing approach demonstrates a potential solution for crack size monitoring through affordable strain gauges.

Summary: Structural health monitoring (SHM) is essential for ensuring safety in various applications. Traditional sensors have limitations, but a new technology using RFID allows wireless transmission of strain measurement data. The novel sensor based on LC circuit and cracked capacitor electrodes offers a wireless strain sensor with high sensitivity. This wire-free, power-free design can be easily integrated into composites without compromising structural integrity, providing a cost-effective and non-destructive solution for accurate structural health monitoring.

Summary: This paper proposes a deformation inspection and monitoring method for grid structures using image-based 3D reconstruction, which accurately recognizes and extracts the deformed shapes of crooked members through a new automated recognition and extraction algorithm. In experiments, the average error of deformation measurements using image-based 3D reconstruction is within 1 mm compared to laser scanning, validating the effectiveness of the proposed method in on-site inspection and monitoring.

Summary: Fatigue experimental setups were used to study crack growth propagation in high-strength low-alloy DMR 249A ship steel under real sea-state conditions. A methodology independent of acoustic emission (AE) parameters was developed to identify crack propagation phenomenon in the specimen. This study also introduced a polynomial regression-based model for estimating the crack growth rate (CGR) in the material.

Summary: The deformation and reconstruction of composite propellers under static load were studied, and a method of using FBG sensors for strain monitoring and reconstruction of CFRP propellers was proposed. A reconstruction algorithm based on strain information was presented and verified in the finite element software. The results showed a relative error within 8% for the reconstruction algorithm. An experimental system based on FBG sensor network for strain monitoring and reconstruction of CFRP propellers was built, and the reconstruction relative error was within 15% compared to measurements from three coordinate scanners.

Summary: A novel experiment strain field reconstruction method (EXP-SFRM) is proposed to improve the accuracy and monitoring effect of conventional strain field reconstruction based on finite element analysis. The method introduces the coordinates of strain gauges to establish connections between discrete strain gauges and finite element analysis. Experimental tests are conducted to validate the high accuracy and good monitoring effect of EXP-SFRM. Compared with conventional FE-SFRM, EXP-SFRM exhibits lower average errors and predicts the buckling regions more accurately.

Summary: This study introduces a general-purpose algorithm that combines neural networks with differentiable particle tracking to efficiently reconstruct high-dimensional phase space distributions without using specialized beam diagnostics or manipulations. The algorithm accurately reconstructs detailed 4D phase space distributions with confidence intervals using a limited number of measurements from a single quadrupole and diagnostic screen. This technique allows for the measurement of multiple correlated phase spaces simultaneously, which will enable simplified 6D phase space distribution reconstructions in the future.
