Abstract This paper presents a fully coupled hygro-thermo-mechanical bond-based Cosserat peridynamic porous
media model for concrete at high temperature [1-3]. The model enables the problem of Poisson's ratio
limitation to be relieved and the effect of cement particle size and its independent micro-rotation to be taken
into account [4]. A multi-rate explicit integration strategy is proposed, which allows this complex multi-field
fully coupled governing equation to be well solved. Numerical simulations mainly focus on the terms of
temperature, water vapour pressure and damage level to verify the validity of the model [5-9]. And they
additionally demonstrate the effect of cement particle… More >
