Micro Abstract:
Crack nucleation and propagation in heterogeneous materials models, as obtained by X-Ray micro-CT imagery, is investigated by the phase field method. Several 3D analyses in highly heterogeneous materials are carried out, with application to cementitious materials. Direct comparisons of complex 3D micro cracking in heterogeneous quasi-brittle materials modeled by the phase field numerical method and observed by imaging during in situ mechanical testing are presented.
