Experimentally measuring weak fracture toughness anisotropy in graphene
<p>Extended finite element analysis (XFEM) modeling the fracture process of 2D materials with anisotropic fracture toughness. Modification from the classic XFEM, this updated script is based on the maximum energy release rate criterion, and anisotropic fracture toughness in sine form and hexagonal symmetry is included. By modifying the ratio of maximum and minimum fracture toughness, model geometry, boundary conditions, and pre-crack location and direction, the fracture patterns, as well as the local fracture parameters including stress intensity factors and energy release rate at the crack tip can be calculated. Moreover, in this script, the distance of the crack extension at every step is irrelevant to the mesh size of the geometry, thus accuracy and computation efficiency is enhanced.</p>

Intrinsic elastic anisotropy of Westerly granite observed by ultrasound measurements, microstructural investigations and neutron diffraction
<p>Westerly granite (WG) has been accepted as an isotropic homogeneous rock. Here we return to WG and observe significant elastic anisotropy using multidirectional ultrasonic sounding on spherical samples at pressures up to 400 MPa. Thermal treatment of WG leads to formation of microcracks that reduce elastic wave velocities and increase its elastic anisotropy. The 3D distribution of P-wave velocities at low pressure is close to orthorhombic symmetry. Application of hydrostatic pressure closes most of thermally induced microcracks and decreases elastic anisotropy of WG, but at high pressure the anisotropy is practically reversed compared to low pressure: maximum P-wave velocity direction at low pressures is near minimum velocity direction at high pressure and vice versa. To understand this effect, microstructures of the rock were investigated by optical and scanning electron microscopy. Preferred orientations of four major rock-forming minerals – quartz, orthoclase, plagioclase and biotite – were measured by time-of-flight neutron diffraction, which confirms significant crystal alignment. All these data were used to numerically model anisotropic elastic properties of WG. It is shown that WG possesses weak intrinsic elastic anisotropy related mainly to the preferred orientation of feldspars formed during igneous crystallization. Observed microcracks are mostly related to the cleavage planes of feldspars and biotite, and thus also demonstrate preferred orientation. Higher preheating temperatures produce larger quantity of longer microcracks. These microcracks act against the weak intrinsic elastic anisotropy of WG, and define the elastic anisotropy at low pressures.</p>
