DAVIS code: data-adaptive spline-based viscoelasticity framework

Data-Adaptive Spline-Based Viscoelasticity (DAVIS) is an open-source computational framework for finite-strain viscoelasticity. The code implements a data-adaptive generalized standard material formulation in which equilibrium and non-equilibrium energy functions and creep potentials are represented by B-spline interpolants. The framework supports FEM-based calibration using full-field DIC data and reaction forces and reproduces the results reported in the associated publication. This record corresponds to software version 1.0.0. Detailed installation and usage instructions are provided in the linked GitHub repository’s README.
