Flexible tissue with fibres interacting with an adhesive surface

An artificial structure of a flexible tissue with rotatable elastic fibres that interact with a rough fractal surface is simulated numerically. We concentrate on a realistic system of relatively hard but slightly flexible fibres contacting an adhesive surface. It is shown that if the flexibility in the direction orthogonal to the average surface is limited, the additional degrees of freedom in other directions become important for better adaptation of the stiff fibres to the fractal surface. Attachment and detachment scenarios with different starting distances, surface roughnesses and pulling angles are simulated
