摘要

Viscoelastic materials are crucial in various applications toward actuation, sensing, and energy harvesting, which demands accurate modeling for predicting real-time behavior. This study examines the pivotal aspect of computational efficiency and precision for the implementation of Maxwell elements in viscoelastic modeling. Maxwell elements, characterized by series-connection of springs and dashpots, form fundamental components for representing time-dependent material behavior in dielectric elastomers (DE). The study explores computational efficiency and precision in various viscoelastic models in varying configurations of Maxwell elements. The analysis encompasses factors affecting computational efficiency, element count, arrangement (parallel/series), material attributes, etc. Furthermore, it delves into the interaction among time step sizes and numerical integration methods to strike a balance between model precision and computational speed. Through extensive simulations, insights are uncovered regarding the optimization of Maxwell element utilization in viscoelastic models, aiming for enhanced computational efficiency and predictive accuracy. These findings offer valuable guidance applicable to researchers and manufacturers involved in DE modeling across diverse engineering domains. This research contributes to a deeper comprehension of the trade-offs between computational efficiency, modeling accuracy, and Maxwell element count, thereby assisting in making informed decisions in the design and analysis of viscoelastic systems.
