Nonlinear Finite Element Analysis of a Conoidal Thin Elastic Shell - Algorithm and Numerical Results
In the Field of civil and structural engineering industry among of the shells, conoidal shells took the greatest advantage to cover large column free areas such as in stadiums, airports and shopping malls.in this paper we investigate nonlinear stress-stain finite element state of a conoidal shell. The algorithm is the one of nonlinear finite elements. Numerical nonlinear analysis is obtained by the RFEM program. Results are presented for the conoidal design models by using finite element method and nonlinearity .keep in mind that the using Finite element method to calculate nonlinearity in the shells is the best way.
