Constitutive-Set Mechanics: variational mechanics on an admissible set of constitutive laws
Altaf Ahmad Lone, R. T. Durai Prabhakaran, Tawqeer Nasir Tak +2
A structural simulation needs a constitutive law, and experiments rarely determine one uniquely: several laws may fit the same data and satisfy the same physical constraints, yet d…

Mechanism-resolved phase-field fracture of composite shells with a certified admissible constitutive operator
Altaf Ahmad Lone, R. T. Durai Prabhakaran, Timon Rabczuk +1
Phase-field models of fracture in fibre-reinforced shells are usually formulated against a single closed-form stored energy, so that the stress, consistent tangent and plane-stress…
