LOAD-DEPENDENT THERMO-MECHANICAL APPLICATION LIMITS

摘要

The common approach to determine thermo-mechanical application limits as the beginning of the decrease of the temperature-dependent modulus from DMA-measurements results in optimistic thermo-mechanical application limits. The reason for it is analyzed and allowable estimations are suggested. Also the time-, stress- and temperature-dependent deformation behaviour at static loading is investigated to derive time- and stress-dependent thermal application limits.
