대변위 및 대회전을 고려한 만곡된 쉘의 기하학적 비선형 해석
A geometrically nonlinear analysis of the curved shell considering large displacements and large rotation increments
초록
This Paper presents a geometrically nonlinear behaviors of shell problems by using the three-dimensional curved shell element, which includs large displacements and large rotations. The standard formulation of the geometrically nonlinearity is restricted to the assumption of infinitesmal rotation increments. This standard formulation for the displacement function is numerically improved by considering the second order expansions of Tayler series. The nonlinear behaviors of the single and double curved shells are compared wi th the other results.
