Abstract:

A solution is presented for the finite deflection of a linearly viscoelastic cantilever clamped horizontally at one end and loaded vertically at the other. The geometrical nonlinearity is incorporated with the viscoelastic equivalent of the Bernoulli-Euler theory of bending of elastic beams. An example using the viscoelastic properties of a new thermoplastic engineering material, delrin, is presented. The approach uses viscoelastic characteristics in the form of the creep compliance which can be measured directly, and can represent arbitrary linear viscoelastic behavior. The method of solution is presented as an example of the incorporation of linear viscoelastic operators into a perturbation procedure which deals with the influence of geometrical non-linearity.
