- The paper describes a novel approach to formulate failure envelopes for foundation macro-element models. For the first time an established mathematical framework (SOS-convex polynomials) is applied to develop foundation macro-element models that are everywhere convex and guaranteed to be thermodynamically consistent. The general approach has future applications in the development of constitutive models for soil, including for cyclic loading. The work arises from doctoral work on suction caisson foundations, fully funded by Ørsted, with the resulting models applied to design at Borkum Riffgrund wind farm (Head of R&D, Ørsted available to corroborate).
