Coupled chemo-mechanical deterioration of cementitious materials. Numerical methods and simulations
The paper deals with the computational aspects of a recently developed coupled chemo-mechanical damage model for cementitious materials [see the foregoing entry] and the numerical analysis of chemi-mechanical degradation on a structural level. In particular, the ingredients of a multifield finite element formulation, characterized by implicit time integration, consistent linearization, a higher-order hierarchical finite element discretization and an iterative Newton-Raphson schemes are presented. The numerical examples demonstrate that the chemo-mechanical damage model together with the numerical methods proposed in the present paper are able to reproduce respective experimental results.
