In this paper a numerical model for autogenous healing of normal strength concrete is
presented in detail, along with preliminary results of its validation, which is planned to be achieved
by comparing the results of numerical analyses with those of a dedicated experimental campaign.
Recently the SMM (Solidification-Microprestress-Microplane model M4) model for concrete, which
makes use of a modified microplane model M4 and the solidification-microprestress theory, has been
extended to incorporate the autogenous healing effects. The moisture and heat fields, as well as
the hydration degree, are obtained from the solution of a hygro-thermo-chemical problem, which is
coupled with the SMM model. The updated model can also simulate the effects of cracking on the
permeability and the restoring effect of the self-healing on the mechanical constitutive laws, i.e. the
microplane model. In this work, the same approach is introduced into a discrete model, namely the
Lattice Discrete Particle Model (LDPM). A numerical example is presented to validate the proposed
computational model employing experimental data from a recent test series undertaken at Politecnico
di Milano
