Material parameter estimation enabled by adaptive deformable body simulation of continuum beam models and real-time visual tracking

Abstract

This study introduces an advanced method for adaptive deformable body simulation using the Euler–Bernoulli beam model and the Timoshenko beam model, incorporating real-time material parameter estimation and visual tracking. The approach addresses significant challenges in accurately simulating the deformation of real-world materials, particularly in the presence of variable material properties and fabrication inconsistencies. By integrating advanced numerical techniques, including the Newmark method for time integration, and removing the reliance on traditional force sensors, this method facilitates dynamic, real-time simulations that closely replicate actual material behaviors. Experimental validation was performed using various materials, demonstrating substantial improvements in the accuracy of displacement predictions and the optimization of elastic modulus values. The results underscore the method’s potential for extensive application in fields requiring precise material modeling and dynamic simulation.
