A Performance Study of First-order Shear Deformable shell Element Based on Loop Subdivision Surface
루프서브디비전 곡면을 이용한 일차전단 변형 쉘요소의 성능에 관한 연구
Abstract
A first order shear deformable Loop-subdivision triangular element which can handle transverse shear deformation of moderately thick shell is developed. The developed element is general since it includes the effect of transverse shear deformation and has standard six degrees of freedom per node.(three translations and three rotations) The quartic box-spline function is employed as interpolation basis function. Numerical examples for the benchmark problems are analyzed in order to assess the performance of the newly developed subdivision shell element. Both in the uniform and in the distorted mesh configurations.
