This paper presents an isogeometric formulation for the linear in-plane free vibration analysis of arbitrarily curved Timoshenko beams. The model is developed using curvilinear coordinates, ensuring a consistent kinematic description and accurate representation of strongly curved geometries. The beam geometry is described exactly using B-spline and...

Development of device for harmonic excitation of engineering structures is presented. Device is developed in order to introduce experimental dynamic analysis of structures to students and engineers. Basic drive mechanisms of device are electric motors whose rotational motion is transferred into translational. This enables possibility for excitement...
