Problems of Architecture and Construction

Abstract

On the basis of numerous studies it can be asserted that the modulus of elastic deformation of aging heterogeneous materials rises with increasing t age, approaching the limiting value of the modules of deformation for inhomogeneous material of very old age. The analysis of experimental studies based on the study of aging materials in the most important cases of their loading shows that the creep measure under conditions of natural in homogeneity for any t is a continuous bounded nonnegative function of t for t>t.
