Finite Strip Computer Application

The FStr computer application program is based on the Finite Strip Method and gives to the user an easy and intuitive elastic buckling analysis, allowing access to the buckling mode shape of thin-walled structural member. Besides the generation of the 2D and 3D buckling modes illustration, the user is able to obtain the critical buckling load and its related member length. FStr Computer Application is a software developed on the basis of the Finite Strip Method formulation. The formulation uses trigonometric functions in longitudinal direction in series, with the purpose of interpolate the solution inside the strip, and form a shape suitable to any type of end boundary condition. Signature curves are one type of analyze the results, through a set of longitudinal lengths. Then, the user can analyze the critical modes in any critical length. 3D buckling modes, with colorful plots, helps the user to identify the critical buckling mode easily.
