A multi-scale based cohesive zone model for the analysis of thickness scaling effect in fiber bridging

John Botsis, Luis Pablo Canal Casado

A cohesive zone model (CZM) is proposed to assess the thickness scaling effect associated with fiber bridging during fracture. The CZM was developed through a multi-scale simulation approach and utilizes an embedded cell model of the Double Cantilever Beam ...

Large scale fiber bridging in mode I intralaminar fracture. An embedded cell approach

John Botsis, Luis Pablo Canal Casado, Georgios Pappas

Fiber reinforced composites can develop large scale bridging upon mode I fracture. This toughening mechanism depends on the constituents and the geometry of the specimen, and is especially important in unidirectional laminates when fracture is parallel to ...

Characterization of intralaminar mode I fracture of AS4/PPS composite using inverse identification and micromechanics

John Botsis, Luis Pablo Canal Casado, Georgios Pappas

A detailed experimental-numerical study of large scale bridging during intralaminar fracture of AS4/PPS uniaxial thermoplastic composite is reported. Identification of bridging tractions is carried out using: (a) An inverse identification method based on q ...

Magneto-mechanical actuation of ferromagnetic shape memory alloy/epoxy composites

Véronique Michaud, Susanne Glock, Luis Pablo Canal Casado

Ferromagnetic shape memory alloys (MSMA) exhibit magnetic field- and stress-induced twinning when processed into single crystals, but are brittle and difficult to shape. Embedding slender single crystalline MSMA elements into a polymer matrix can thus prov ...

An experimental-numerical investigation of hydrothermal response in adhesively bonded composite structures

Hans Georg Limberger, John Botsis, Véronique Michaud, Roohollah Sarfaraz Khabbaz, Georgios Violakis, Luis Pablo Canal Casado

Water absorption and thermal response of adhesive composite joints were investigated by measurements and numerical simulations. Water diffusivity, saturation, swelling, and thermal expansion of the constituent materials and the joint were obtained from gra ...

Process-induced strains in RTM processing of polyurethane/carbon composites

Véronique Michaud, Michael Hausmann, Maria Benavente Miana, Luis Pablo Canal Casado

The development of residual strains and stresses is critical to manufacture composite structures with the required dimensional stability and mechanical performance. This work uses Fiber Bragg Grating (FBG) sensors to monitor strain build-up in carbon fiber ...

Novel experimental procedure and determination of full displacement fields of delaminating composite layer interfaces for evaluation of the mode II cohesive law

Luis Pablo Canal Casado

A novel mode II fracture test setup based on a simple tensile loading scenario with a discontinuous ply specimen is proposed in the paper as the first step towards determination of the cohesive law of composite layer interfaces. Key outputs of the procedur ...

Micro-scale modeling of water diffusion in adhesive composite joints

Véronique Michaud, Luis Pablo Canal Casado

Water diffusion into composite adhesive joints was experimentally studied by means of gravimetric measurements in bond specimens. The main parameters controlling the diffusion in the bond components were obtained from water uptake experiments carried out i ...

Monitoring strain gradients in adhesive composite joints by embedded fiber Bragg grating sensors

Hans Georg Limberger, John Botsis, Véronique Michaud, Roohollah Sarfaraz Khabbaz, Georgios Violakis, Luis Pablo Canal Casado

The adhesive bonding of composite materials can be applied to assemble light-weight structures for aeronautical applications. However, the application of adhesive bonds in primary load-bearing structures is limited by the lack of adequate techniques to mon ...
