METHOD FOR NON-DESTRUCTIVE MEASUREMENT AND CONTROL OF DIFFERENCE OF VISCOELASTIC AND ULTIMATE STRAINS OF HYGROSCOPIC MATERIALS IN PROCESS OF DRYING

摘要

Disclosed is a method for non-destructive measurement and control of difference of viscoelastic and ultimate strains of hygroscopic materials in process of drying. It is realized by direct method through determination of difference of total deformations on surface of hygroscopic material with minimum instantaneous modulus of elasticity and standard to which external mechanical load proportional to limit of long-term resistance is applied.
