Predicting the Deformability of Expanded Polystyrene in Long-Term Compression

The interval prediction of creep strain on the basis of 15 years is carried out for slabs of expanded polystyrene (EPS) subjected to a compressive load. The expansion of the confidence interval caused by the discounted prediction information is allowed, for by an additional factor. The creep complia...

Summary:The interval prediction of creep strain on the basis of 15 years is carried out for slabs of expanded polystyrene (EPS) subjected to a compressive load. The expansion of the confidence interval caused by the discounted prediction information is allowed, for by an additional factor. The creep compliance Jc (t =15)of the EPS is determined based on empirically estimating the long-term creep of this material subjected to a compressive stress sigmac = 19.35sigma10% for 15 years. A relationship between Jc (t = 15) and EPS density in the slabs is established.
