Measuring mode II fracture toughness at a dissimilar interface using the Transverse Crack Tensile may be challenging, particularly if geometric and elastic symmetry conditions are not maintained during crack propagation. Building on previous results,... Read More about Extending the Modified Transverse Crack Tensile test for Mode II Fracture Toughness Characterisation of Hybrid Interfaces.

A critical review on free edge delamination fracture criteria (2024)
Journal Article

Laminates experience three-dimensional singular stress near their free edges due to elastic mismatches between layers, which can cause delamination. This paper critically evaluates methods for predicting free edge delamination and highlights the limi... Read More about A critical review on free edge delamination fracture criteria.

Stress-based topology optimization using maximum entropy basis functions-based meshless method (2024)

Engineering Fracture Mechanics, 307, Article 110274. https://doi.org/10.1016/j.engfracmech.2024.110274

Traditional approaches that rely on stress or energy-based criteria to predict delamination require the determination of stresses before crack onset or energy release rates after crack initiation, respectively. While a relatively new coupled criterio... Read More about Investigating factors influencing interlaminar stresses and energy release rates of semi-elliptical cracks at free edges.
