Shape Estimation of Structures Undergoing Dynamic Stress

Abstract

Described herein are systems and techniques for estimating a shape of a structure undergoing dynamic stress. In some embodiments, a method includes: for each of a plurality of nodes distributed along a length of the structure, obtaining, from an accelerometer located at the node, a tilt angle corresponding to an angle between a local axis of the structure and a direction of gravity; calculating, by a microcontroller, vertical displacements between adjacent pairs of the plurality of nodes using the respective tilt angles obtained for the adjacent pairs; and calculating, by the microcontroller, a depth of each of the plurality of nodes relative to a proximal end of the structure by adding the vertical displacements calculated for adjacent pairs of the plurality of nodes between the node and the proximal end of the structure.
