Overview

Structural mechanics studies how solids, beams, shells, lattices, and other structures deform, carry loads, vibrate, buckle, and fail, linking material behavior and geometry to safety and design. Work combines finite-element and variational methods with experiments, while reduced-order models, physics-informed networks, graph neural networks, and neural operators aim to predict stress fields and dynamic responses at lower cost. These approaches address nonlinear elasticity, composites, fracture and contact, crash behavior, architected materials, and inverse tasks such as identifying loads or defects; topology and reliability-based optimization use them to find designs under constraints and uncertainty. A central challenge is preserving physical consistency while generalizing to new geometries, meshes, materials, and loading histories, and validating predictions against high-fidelity simulations and experiments.
