In this paper, using finite element method, a FEM model of wind turbine towers with the consideration of soil-structure interaction using spring-damping element was proposed to investigate their dynamic response to multi-dimension seismic excitation in time domain. The updated Lagrange FEM formalism has been adapted to discrete the equation and use Newmark integral method to solve it step by step...
In this study, the dynamic behavior of the sandwich panels subjected to the impact load are investigated experimentally and numerically. For this purpose, the sandwich panels are manufactured using the honeycomb core material and laminated composite face sheets. The face sheet materials used in this study are manufactured using an aramid fabric and epoxy resin. The wet hand lay-up technique is used...
