Abstract This paper presents the fundamental mechanical properties that characterise constitutive behaviours of GCCM for large-strain problems in unidirectional tensile and axi-symmetry puncture tests. The 2D nonlinear FEA was conducted to simulate the GCCM behaviour. The optimised stiffness parameters can simulate the elastic behaviour of GCCM. The post-cracking governed by inelasticity of woven geotextile is modelled by bilinear stress-strain relationship. The interface between woven geotextile and cement layer is explained by the existing bond-slip model. The analytical results are presented in terms of load-displacement curves as well as the crack patterns, which are similar to the experimental results.
