Abstract

Thermoplastic materials, having a high chemical stability, are used on a very large scale in corrosive environmental media. Nevertheless, in many cases unexpected failure occurs, since valid construction guide‐lines are missing.

For this reason, in the present work a deformation‐related dimensioning criterion is presented, based on the appearance of first irreversible material‐damage.

Further, the sorption‐, swelling‐, short‐term‐ and creep‐behaviour of PMMA in the presence of distilled water are described and discussed. Finally, mathematical and graphical procedures for the determination of the creep‐strain under different loading and environmental conditions are shown and explained.
