Summary on Grant Application Form
A flexible boundary cubical cell is to be constructed and fitted with piezo-ceramic bender and compression elements in several faces in order to provide an apparatus which can be used to study the effects of complex stress states and stress histories, with controlled variation of three principal stresses, on the stiffness of soils at very small strains. The arrays of bender elements will provide information from which the changing anisotropy of small strain shear stiffness of clays and sands can be deduced. Compression elements in the faces will provide values of compression wave velocity across dry sand samples. Data of stress:strain response over small to medium strains will also be obtained for use in developing and refining constitutive models of soil response and link elastic-plastic anisotropy with the recorded elastic anisotropy.
