Neural network hysteresis modeling with an improved Preisach model for piezoelectric actuators

Weiping Guo, Diantong Liu, Wei Wang

Widely used in micro‐position devices and vibration control, the piezoelectric actuator exhibits strong hysteresis effects, which can cause inaccuracy and oscillations…

Design and optimization of microstructure of auxetic materials

Akbar A. Javadi, Asaad Faramarzi, Raziyeh Farmani

Auxetic materials differ from conventional materials by the manner in which they respond to stretching; they tend to get fatter when stretched, resulting in a negative…

Application of homotopy perturbation and numerical methods to the magneto‐micropolar fluid flow in the presence of radiation

Mohammad Madani, Yasir Khan, Mahdi Fathizadeh, Ahmet Yildirim

The purpose of this paper is to report the effect of radiation on flow of a magneto‐micropolar fluid past a continuously moving plate with suction and blowing.

Numerical implementation of a damage‐coupled material law for semicrystalline polyethylene

J.A. Alvarado‐Contreras, M.A. Polak, A. Penlidis

The purpose of this paper is to provide a computational procedure for a novel damage‐coupled material law for semicrystalline polyethylene. Using a damage mechanics…

Experimental study on sound radiation time‐frequency characteristics of double cylindrical shell based on EMD

Fang Ji, Xiongliang Yao, Aman Zhang, Xi Ye

Laying the acoustic decoupling material on the surface of underwater structures is an effective noise reduction technology. The underwater sound radiation experiment of…

On the design and implementation of parallel finite element approximate inverses using POSIX threads on multicore systems

G.A. Gravvanis, P.I. Matskanidis, K.M. Giannoutakis, E.A. Lipitakis

The purpose of this paper is to propose novel parallel computational techniques for the parallelization of explicit finite element generalized approximate inverse methods…
