Abstract

Abstract: In this paper, to fully explore the mechanical characteristic of hollow glass microspheres (HGM) composites in deep-sea environment, the compressive behavior of solid buoyancy materials under different temperature gradients and various stress states were studied by a triaxial test system. Through the analysis of experimental results, the glass transition temperature and energy absorption of the material were revealed. Such a content, will further be useful to construct the yield criterion and specialize the sensitivity of each parameter. Highlights: The mechanical behavior of solid buoyant material is studied under high/low temperature coupled complex stress environment. The advanced varied temperature and high-pressure Rock Triaxial Testing System is used for material performance experiment. This article is of great significance to explore the failure mode of this material in deep-sea environment. The experimental data establish a basis for the yield surface and plastic behavior of materials at different temperatures.
