# The Gradient Flow Structure of an Extended Maxwell Viscoelastic Model and a Structure-Preserving Finite Element Scheme

@article{Kimura2019TheGF, title={The Gradient Flow Structure of an Extended Maxwell Viscoelastic Model and a Structure-Preserving Finite Element Scheme}, author={Masato Kimura and Hirofumi Notsu and Yoshimi Tanaka and Hiroki Yamamoto}, journal={Journal of Scientific Computing}, year={2019}, volume={78}, pages={1111-1131} }

An extended Maxwell viscoelastic model with a relaxation parameter is studied from mathematical and numerical points of view. It is shown that the model has a gradient flow property with respect to a viscoelastic energy. Based on the gradient flow structure, a structure-preserving time-discrete model is proposed and existence of a unique solution is proved. Moreover, a structure-preserving P1/P0 finite element scheme is presented and its stability in the sense of energy is shown by using its…

Two means of handling the nonlinearity are discussed: either implicitly, which requires the solution of nonlinear equations at each time level, or through a linearisation based on extrapolating from previous time levels, which are proven to have the same optimal orders of convergence.
