Evaluation of the strain-based partitioning method for mixed-mode I+II fracture of bi-material cracks

The goal of this paper is to evaluate the strain-based partitioning method (SBM), an analytical method based on beam analysis, for the mixed-mode fracture characterization of asymmetric cracks. The fracture energy is calculated at the crack tip of mixed-mode bending (MMB) test with asymmetric geometry and asymmetric material parameters. The...

On the influence of glass fiber mat on the mixed-mode fracture of composite-to-metal bonded joints

In this work, the influence of a layer of glass fiber mat (GFM) inserted in a bi-material bonded joint interface is investigated as a toughening mechanism to improve the fracture performance of bonded structures. Composite-to-metal bonded specimens were manufactured by hand lay-up using two different consolidation processes: at room pressure...

Strain-based methodology for mixed-mode I plus II fracture: A new partitioning method for bi-material adhesively bonded joints: A new partitioning method for bi-material adhesively bonded joints

The dissemination of composite materials introduces applications of hybrid structures with composite and metal parts. The development of reliable methodologies to evaluate the performance of these structures is required. In this work, the mixed-mode fracture behaviour of a bi-material adhesively bonded joint is investigated. A new strain...
