Finite strip method

The finite strip method (FSM ), Eng. finite strip method is a numerical calculation method, which is a simplified form of the finite element method ( FEM).

The FSM is applicable to problems whose geometry and material properties do not change in one or several directions. The plates can be for example, but also discs, bowls or profiles. Then the computational domain into uniform, interconnected strips (elements) divisible ( disketisierbar ).

For the first time, the finite strip method was published by YK Cheung 1968, who calculated the static deflection of plates with her.

Example

The finite strip method can be applied to buckling and stability problems of linear elasticity theory. The plates or profiles can be fitted with stiffeners in the longitudinal or transverse direction. You can also be mounted on springs. As load longitudinal and transverse normal forces and shear forces can occur.
