  • Virtual Lab
    – GENERAL:

    a. Material Database Management System based on SQL techniques
    b. User-configured automatic reporting for parameter identification sessions
    c. Extension of the power law migration tool to 3 available formulations for stress dependent stiffness in the Hardening Soil model
    d. Improved algorithm for parameter migration between 3 available power law formulations in the the Hardening Soil model
    a. possibility of defining bounds on the power exponent m for numerical adjustments for triaxial tests

    b. revised automatic selection for void ratio, dry unit weight and friction angle for coarse soils
    a. new Loading Program Manager to design most common triaxial loading programs to examine constitutive models w/o real test data:
    i. strain or stress-controlled test
    ii. monotonic w/ or w/o unloading cycles
    iii. cyclic loading with one- or two-way amplitudes
    b. new Brick formulation for small strain stiffness extension in the Hardening Soil model
