Modeling of Magnetorheological Elastomers Using the Elastic⁻Plastic Model with Kinematic Hardening

摘要: The paper describes the modeling process of magnetomechanical properties magnetorheological elastomers. Unlike primary sources in which a viscoelastic model is commonly used, this work, elastic⁻plastic with linear hardening was adopted. Its parameters were determined from data obtained an experiment. Measurement encompassed range various strain rates and amplitudes, as well magnetic field values. Model function result identification. correctness correlation shown by comparing hysteresis loops τ ( γ ) . Satisfactory consistency between experimental research achieved on assumption that applied only to higher rates, above boundary value ˙ A = 0.025 1 / s
