| The project focuses on simplifying the transition between field or laboratory tests and constitutive models and their calibration in the environment of geotechnical tasks and computational soil mechanics. A constitutive model that captures the behavior of a material within a general range of loading conditions is essential for simulating complex boundary problems in soil mechanics and geomaterials. Ideally, conventional constitutive models used in geomechanics (MC, CamClay, Hypoplasticity) could be parameterized using a single (complex) test, which is at least partially fulfilled by the penetration test. The principle of the CPT test is the static insertion of a measuring cone using a system of steel rods into the investigated environment at a constant rate. Direct evaluation of constitutive parameters in the case of the CPT test is considerably challenging but shows potential when using alternative approaches such as constitutive models based on neural networks. |
