Benchmark case studies in optimization of geometrically nonlinear structures
Afzal Suleman,Ramin Sedaghati +1 more
TL;DR: In this paper, a structural optimization algorithm is developed for truss and beam structures undergoing large deflections against instability, which combines the nonlinear buckling analysis using the displacement control technique, with the optimality criteria approaches.
Journal ArticleDOI
Temperature dependency of magnetorheological fluids’ properties under varying strain amplitude and rate
TL;DR: In this paper, a rotary rheometer was used to evaluate the effects of temperature and magnetic field on the pre- and post-yield properties of magnetorheological (MR) fluids.
Journal ArticleDOI
Development of a new torsional vibration damper incorporating conventional centrifugal pendulum absorber and magnetorheological damper
TL;DR: In this article, a hybrid torsional vibration damper is proposed incorporating a conventional centrifugal pendulum vibration absorber and a magnetorheological damper, which can attenuate vibration under unpredictable environmental conditions.
Journal ArticleDOI
Modeling and dynamic analysis of a vehicle-flexible pavement coupled system subjected to road surface excitation
TL;DR: The system response due to the moving vehicular load on rough road supported by a linear visco-elastic foundation was investigated and the effects of parameters such as vehicle speed, road roughness, soil stiffness and suspension damping on the responses were investigated.
Journal ArticleDOI
Optimization of thin-walled structures with geometric nonlinearity for maximum critical buckling load using optimality criteria
TL;DR: In this article, two optimality criteria are presented for shape optimization of thin-walled structures with geometric nonlinearity modeled by finite elements, and the optimization problem considers the thickness and geometry design variables, and aims to maximize the critical load of the structure subject to constant total mass.
