Finite element analysis facilitates optimal design of MEMS/NEMS devices for reliability. The same is used here to analyze the effect of types of fractal rough surfaces on static response of nanobeams Three-dimensional rough surfaces are generated using modified two variable Weierstrass-Mandelbrot function with given fractal parameters. Beam with various fractal roughness are modelled to observe the variations in the bending stresses and displacements. The results of the analysis will be useful to designers to develop the most suitable geometry for nanostructures.
