Abstract: Based on the theoretical studies on the failure of homogeneous isotropic brittle materials, failure criteria of the materials under combined stresses are represented as convex surfaces in the principal stress space. The failure surface of lightweight aggregate concrete was determined experimentally through uniaxial, biaxial and triaxial compression tests with about two hundred of 10.5 cm cube specimens. The surface is convex and has the space diagonal as a threefold rotation axis. The surface expands with an increase of hydrostatic pressure. The right sections of the surface are slightly bulged from equilateral triangles and become more bulged as hydrostatic pressure increases.
