Automatic differentiation in finite element stress updating

The use of AD is introduced in nonlinear finite element analysis, focusing on stress updating, a key and repeatedly executed step in which stresses are computed from strain increments, demonstrating that automatic differentiation can streamline the development of nonlinear material models.

A reduced order model framework suitable for geotechnical problems

Data-driven methods are of increasing popularity for solving problems in geotechnics, offering as they do, the possibility of high-fidelity results without the effort of a detailed deterministic numerical analysis (e.g. using finite elements). A wide range of approaches fall under the heading of Reduced Order Models...
