Combined computational-experimental investigation of residual stresses and pre-cracking in mode I behaviour of thick adhesively bonded GFRP composite joints

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

This paper presents a novel Finite Element (FE) simulation approach to examine the mode I fracture of thick adhesive joints used particularly in the trailing edge of the wind turbine blades. The approach involved FE models of the DCB specimens focusing on ...

A new equivalent crack length technique for mode I fracture of adhesively bonded joints

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

The current investigation introduces the concepts of the equivalent crack length approach for thin and thick adhesive joints. Its applicability is assessed for adhesively bonded composite and steel joints with a bondline thickness ranging from 0.4 mm to 10 ...

An experimental and analytical study of mode I fracture and crack kinking in thick adhesive joints

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

This study investigates the fracture behavior of thick adhesive joints manufactured with composite adherends and bonded with an epoxy-based structural adhesive common to the wind turbine industry. For that purpose, double cantilever beam specimens with an ...

Improved Material Formulations for Thick Adhesive Joints in Wind Turbine Blades

Jialiang Fan

Wind turbine rotor blades are usually fabricated using composite materials and epoxy adhesive to bond the elements together. Due to their large size, the thickness of the adhesive layer varies from 1 to up to 30 mm depending on the position. The failure of ...

Healable adhesive paste development for thick adhesive joints

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

A new adhesive formulation is developed, enabling assisted self-healing for wind turbine rotor blade (WTRB) applications. The properties of this epoxy based formulation are compared to those of a state-of-the-art toughened epoxy adhesive (Sikapower (R)-830 ...

Void content and displacement ratio effects on fatigue crack growth in thick adhesively bonded composite joints under constant amplitude loading

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

This article investigates the influence of displacement ratio (R d-ratio) and void content on the fatigue behavior of Double Cantilever Beam (DCB) joints with thick adhesive layer (10 mm). Two R d-ratios and two different void contents were studied. To ach ...

Mode I fracture of thick adhesively bonded GFRP composite joints for wind turbine rotor blades

Véronique Michaud, Anastasios Vassilopoulos, Jialiang Fan

This article investigates the effects of voids, joint geometry, and test conditions on the quasi-static Mode I fracture performance of thick adhesive Double Cantilever Beam (DCB) joints such as those prevailing in wind industry and shipbuilding. The specim ...
