Monopiles are the most popular foundation for offshore wind turbines. These foundations typically have a low length to diameter ratio and undergo rigid body rotation when subjected lateral load. This paper presents results from an extensive numerical investigation involving 3D finite element analyses demonstrate that moment-rotation response of monopile in sand can be represented using single n...

a new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. the total elastic modulus of nano-composite is evaluated.  numerical results are in good agreement with the previous proposed theoretical modeling. higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.
