“…An asymmetry between the tension and compressive responses is often observed for quasi-brittle granular materials (see Mazars et al, 1990 for concrete; Thomson et al, 2010 for PBX-9502; Buechler et al, 2012a for PBX-9501; and Picart et al, 2014 for M1). When these materials are submitted to alternating tension/compression loading, a stiffness recovery is observed at the beginning of compression (Mazars et al, 1990;Picart et al, 2014). This phenomenon is called unilateral effect and is classically related to damage.…”

“…Zubelevicz et al (2013) have introduced different damage rates in tension and compression coupled with viscoplasticity. Lastly, a microplane model with anisotropic damage added to non-associated plasticity with isotropic hardening was proposed by Benelfellah et al (Benelfellah, 2013;Benelfellah et al, 2014Benelfellah et al, , 2017Picart et al, 2014).…”

“…The mechanical tests of material properties show that PBX exhibits different mechanical behaviours under different stress states [17][18][19], which brings great difficulties to numerical modelling [20][21][22]. In present study, the stress state dependent strength model and nonassociated flow rule are applied to describe the nonlinear constitutive behaviour of the material under complex stress states.…”

PBX solid high explosive exhibits brittle behaviour in uniaxial tension, quasi-brittle in uniaxial compression, and ductile when subject to high confining pressure. Tension cracking is the primary failure mode of PBX quasi-brittle solid, which is the main effect leading to overall failure of structural integrity. One characteristics of brittle or quasi-brittle solids, such as PBXs, is that when subject to overall compressive loading, the tensile cracks can still initiate inside the material due to existence of imperfection within the materials. In present study the extended finite element method is applied to analyze the cracking failure mechanism in the PBX 9502 platelike specimen with cavity subjected to overall compression. The nonlinear constitutive behaviours and failure of PBX under complex stress states were described by means of stress state dependent strength surface, non-associated flow rule and cohesive model the nonlinear behaviors of PBXs, including failure. Analysis indicates the tensile stress around the cavity arises in the specimen although loaded by overall compression, and this local tensile condition leads to cracking initiation. The comparison between simulation results and the experimental data published by LANL[Liu C, Thompson D G. Crack initiation and growth in PBX 9502 high explosive subject to compression. Journal of Applied Mechanics, 2014, 81(10):212-213] shows that they are in agreement with each other on some aspects of crack behaviours, including overall development of crack history and inflexion, crack initiation moment, crack initial speed, etc.
