The bending strength of cantilever beam, which is formed by map function, has been investigated. The map function contains a parameter m and p which are able to change a shape of a curve, and its shape is symmetrical in the case of m=3. From the calculated results of stress, it has been found that the stress of cantilever beam formed by the map function of m=3 and m=1.5 shows the uniform strength, and the stress of beam of m=2 shows the minimum value. Though the A1 bifurcation splits firstly in the case of m=2, the bifurcation of A1 and the stress of cantilever beam are influenced by the shapes of a map function.
