The effect of ageing and anisotropy in 3D-printed composites including short carbon fibres
embedded in a polyamide (PA/nylon®) matrix is analysed experimentally. A testing …

The propagation behavior of hydraulic fractures (HFs) in unconventional shale formation is
influenced by anisotropic fracture toughness and interaction with existing nature fractures …

The bedding angle has a significant influence on the fracturing of anisotropic geomaterials,
such as shale rock, and crack deflection usually takes place during crack propagation. To …

We propose a new phase-field damage formulation which takes into account anisotropic
damage evolution in solids. Such anisotropy projects itself in fracture energy values which …

The two-dimensional nature of graphene offers a number of interesting mechanical
properties. Amongst these, fracture toughness has received substantial interest, yet …

The goal of the current work is to explore direction-dependent damage initiation and
propagation within an arbitrary anisotropic solid. In particular, we aim at developing …

The fracture characterization of shale rocks requires understanding the scaling of the
measured properties to enable the extrapolation from small-scale laboratory tests to field …

One of the complexities of rock engineering is predicting the fracture, especially in cases
where the rock material exhibits anisotropy in both elastic and fracture properties. In this …

Fracking is widely applied to enhance shale gas mining, and insight into the fracture
behaviors of shale rocks is important. To characterize the fracture properties of Lower …

A powerful semi-analytical method is developed to investigate the impact of tough inclusions
on crack paths and the resulting effective fracture properties. Using a perturbative approach …
