Прогностическая оценка деформации ползучести полистирольного пенопласта при постоянном сжатии на базе короткого прямого эксперимента

Abstract

The results obtained in investigating the creep of expanded polystyrene under compressive loading are presented. On the basis of long-term experiments creep compliance under permanent compressive stress sc = (0,25-0,35)s10% was determined. The dependence of creep compliance on the compressive stress s10% of expanded polystyrene was established. Variation of creep compliance in time by the coefficient mi is represented. On the basis of short-term experiments method of prediction of creep strain of expanded polystyrene is presented.
