Simulation of chemo-thermo-mechanical problems in cement-based materials with Peridynamics

Abstract A chemo-thermo-mechanical problem is solved using a peridynamic approach to investigate crack propagation in non-reinforced concrete at early-age. In the present study, temperature evolution and variation of hydration degree conjunction with mechanical behaviour cement-based materials are examined. Firstly, new model introduced solve fully coupled chemo-thermal problems by satisfying thermal equilibrium condition law simultaneously then effects analysis imposed framework all interactions. The proposed used 2D chemo-thermo-elastic it applied fracture structures. Additionally, we examine accuracy method comparing paths, those achieved applying other numerical methods experimental data available literature. good agreement obtained between sets results.
