Shape Sensing of Plate and Shell Structures Undergoing Large Displacements Using the Inverse Finite Element Method

<div>Wing-shaped plate model. (a) Geometry and boundary conditions (thickness 3 mm) and (b) triangular mesh for both FEM and iFEM analysis (132 elements), 44 inverse elements with linear strain gauges oriented along two sensing lines (for a total of 88 strain measurements).</div>
