Research on large deflection deformation reconstruction of elastic thin plate based on strain monitoring
journal contribution
posted on 2019-10-15, 10:36 authored by Wenrui Wang, Yu Lu, Dezong Zhao, Jiaming Zhang, Xuesong Bai© 2019 Elsevier Ltd In this paper, a method of reconstruction deformation by measuring surface strain is proposed. Aiming at large deflection deformation of the four-sided fixed elastic thin plate structure, an algorithm for reconstructing deformation field based on surface strain monitoring is developed. The reconstruction method theoretically analyzes the thin elastic plate according to the large deflection deformation hypothesis and elastic mechanics. The experimental platform for strain monitoring of thin plate and several different loading conditions was established. Based on the analytic solution of deformation and strain from experimental, the deformation surface diagram of thin plates under different loads are obtained. The experimental results show that the average error of reconstruction of the elastic thin plate structure is 4.9%. This measurement method obtains deformation indirectly by measuring strain, and does not need to use too much space to install measuring equipment.
