Estimation of dynamic structural displacements using fiber Bragg grating strain sensors (2007, background): “Even though many relevant works have been accomplished, most of them have taken into account the estimation of static deformations only [1, 2, 5, 6].”
An enhanced inverse finite element method for displacement and stress monitoring of multilayered composite and sandwich structures (2017, background): “In addition to the studies concerning the shape sensing of beam-type structures, the real-time monitoring of plate structures has been considered by several authors [22-25].”
Shape sensing methods: Review and experimental comparison on a wing-shaped plate (2018, methodology): “On the other hand, the accuracy of the Modal Method depends on the number of modes used.”
A quadrilateral inverse-shell element with drilling degrees of freedom for shape sensing and structural health monitoring (2016, methodology): “[3] discussed an inverse algorithm, which uses the deformation of the structure and strain modes together with the discrete strain data to regenerate the deformed shape of plates subjected to arbitrary static loading.”
