LVI has become a serious threat to the composite industry because it induces complex
failure mechanisms and internal damages which significantly reduce the structural …

In the last decade, synthetic fiber, as a reinforcing specialist, has been mainly used in
polymer matrix composites (PMC's) to provide lightweight materials with improved stiffness …

Shale reservoirs are extensively exploited using hydraulic fracturing, which forms multiple
cracks that connect with the existing natural fractures to create a continuous path for the gas …

The transition zone was defined as an interface with certain thickness, strong heterogeneity
and anisotropy in the vertical profile for layered formations, which had great effect on …

In this paper, a detailed FDEM approach to simulate the mechanical and fracturing
responses of heterogeneous geomaterials with irregular inclusions is systematically …

In this paper, a simplified micro-model approach utilising a combination of plasticity-based
constitutive models and the extended finite element method (XFEM) is proposed. The …

Low-velocity impact damage can drastically reduce the residual strength of a composite
structure even when the damage is barely visible. The ability to computationally predict the …

Low-velocity impact (LVI) on continuous fiber reinforced thermoplastics (CoFRTPs) has
been extensively studied with a focus on single material. Impact characteristics and optimal …

One of the fundamental aspects in cohesive zone modeling is the definition of the traction-
separation relationship across fracture surfaces, which approximates the nonlinear fracture …

Impact resistance and damage tolerance are of great significance in the design of composite
structures. This study investigated the damage and failure mechanism of thin composite …
