Viscoelastic Effects in the Design of Equipment and Structures.
Abstract
In recent years the greatly increased use of polymers in the manufacture of components and equipment has led to an increased need for the application of viscoelastic stress analysis to ensure satisfactory design and operation of such items. Moreover, other materials, the structural application of which has been commonly based on elastic analysis, have been found to exhibit rate and time dependent proper-ties on the basis of more precise measurements. The creep and viscoelastic response of concrete provides an example. Visco-elastic material characteristics can have either a beneficial or detrimental effect on the performance of an item of equipment. For example the associated damping may be needed to reduce vibration, or creep deformation might reduce load carrying capacity. Examples of such problems which have arisen in practice are described in this paper. (Author-PL)
