Brittle solids typically fail by growth and propagation of a crack from a surface flaw. This
process is modelled using linear elastic fracture mechanics, which parameterizes the …

In this work, a phase-field formulation is proposed to describe ductile fracture in fiber-
reinforced concrete materials. By incorporating an elastoplastic bulk material formulation …

The interaction between stress fields at the crack-tip and nearby microstructural
heterogeneities influences the crack path, and in turn, the effective fracture toughness of a …

Inclusions embedded in rock materials highly affect their mechanical response and fracture
behavior under external loadings. In this study, dynamic uniaxial compressive tests were …

Material failure is mediated by the propagation of cracks which, in realistic 3D materials,
typically involves multiple coexisting fracture planes. Multiple fracture-plane interactions …

The realistic approximation of structural behavior in a post fracture state by the phase-field
method requires information about the spatial orientation of the crack surface at the material …

In the field of computational modeling of material failure mechanisms, a classical brittle
damage model commonly leads to an ill-posed system of equations in numerical …

Abstract The Sub-Rayleigh to supershear transition is commonly accepted to be governed
by the Burridge-Andrews mechanism. Such a mechanism predicts the direct nucleation of a …

In fracture mechanics, polyacrylamide hydrogel has been widely used as a model material
in experiments due to its optical transparency, the brittle nature of its failure, and low …

Materials with a negative Poisson ratio have the counterintuitive property of expanding
laterally when they are stretched longitudinally. They are accordingly termed auxetic, from …
