The focus of this dissertation is to use analytical and numerical methods to determine mechanisms which increase or decrease the adherence force between micro-scale components. Several different methods are used to accomplish this task: 1) a traditional statistical approach is used to analytically determine the adherence force as a function of surface roughness; 2) a semi-analytical solution is developed for the adhesion of isotropic rough surfaces; 3) a numerical approach utilizes a three-dimensional surface characterization to determine adherence force trends with respect to roughness and material parameters; 4) combining a micro-scaled friction model with item 3), static friction forces are determined as a function of material parameters as well as surface roughness. To inspire further rough surface solutions, an adhesive solution for cylinders is extended to include the solution regime for when there is no longer intimate contact, but adhesive forces are still active. For each of these methodologies there are advantages and disadvantages which arise from the assumptions made in constructing the solution, which are subsequently discussed.
