INFRARED VIBROTHERMOGRAPHY OF COHESIONLESS SOILS. PROCEEDINGS OF THE ELEVENTH INTERNATIONAL CONFERENCE ON SOIL MECHANICS AND FOUNDATION ENGINEERING, SAN FRANCISCO, 12-16 AUGUST 1985

The rheological properties of non-cohesive soils subjected to transient vibratory stresses can be interpreted at the particle level where solid particles develop a complex interaction leading to a few predominant macroscopic deformation mechanisms. The vibrothermography used proved to be a non-destructive test facilitating the observation and real-time recording of isothermal networks produced by the dissipation of heat due to friction between particles. By coupling mechanical and thermal energies, it offers the possibility of detecting the threshold of grain restructuring or characteristic threshold of the granular material. Above this threshold with a zero rate of dilatancy, the damaged soil is subject to a progressive deterioration in its shear strength. But below this characteristic threshold, the material is subject to densification with improved mechanical properties. For the covering abstract of the conference see IRRD 287689. (TRRL)
