Nettet13. apr. 2024 · In this section, firstly, a stable data-driven structural analysis (DDSA) algorithm for three-dimensional continuum structures under finite deformation is proposed. Then the effectiveness of DDSA algorithm is verified by a numerical example. Finally, the solution techniques of the corresponding DDTO framework are given. Nettetpure shear stretch tensors are stated and a new notion of idealized finite simple shear is introduced, showing that for certain classes of nonlinear materials, the results by Destrade et al. can be simplified considerably. Key words: nonlinear elasticity, finite isotropic elasticity, constitutive inequalities, stress tensors, Cauchy stress,
