Micromechanical design of hierarchical composites using global load sharing theory

William Curtin, Varun Parameswaran Rajan

Hierarchical composites, embodied by natural materials ranging from bone to bamboo, may offer combinations of material properties inaccessible to conventional composites. Using global load sharing (GLS) theory, a well-established micromechanics model for c ...

Studies on large scale bridging in delamination of unidirectional and cross-ply laminates

Ebrahim Farmand Ashtiani

Delamination propagation in fibrous laminates is often accompanied by development of a damage zone, within which intact fibers bridge the crack faces that constitutes a major toughening mechanism. A direct experimental assessment of the crack closure tract ...

Energy dissipation during delamination in composite materials - An experimental assessment of the cohesive law and the stress-strain field ahead of a crack tip

Luis Pablo Canal Casado

This paper presents detailed experimental information on mode-II delamination development in fibre/epoxy composite materials and provides observations about the process zone in the vicinity of the crack tip. It is shown that the energy dissipated in delami ...

Tribocorrosion under fluid lubrication

Shoufan Cao

Wear is still the key problem causing the failure and limiting the lifetime of artificial hip joints, especially for the polymer acetabular cup in the metal-on-polymer and ceramic-on-polymer articulations. To reduce the wear, metal-on-metal articulation ha ...

Creep-fatigue interaction in composite materials

Thomas Keller, Anastasios Vassilopoulos, Abdolvahid Movahedirad

A novel phenomenological model taking into account the creep-fatigue interaction in composite materials’ fatigue performance is introduced in this paper. The model is based on the derivation of a master curve by using existing experimental fatigue data fro ...

Evaluation of Young's modulus of MgB2 filaments in composite wires for the superconducting links for the high-luminosity LHC upgrade

Barbora Bártová

MgB2 wire is a promising superconductor for the superconducting links for the high-luminosity upgrade of the large Hadron collider at CERN. The mechanical properties of MgB2 must be fully quantified for the cable design, and in this study, we evaluate the ...

20 Hz X-ray tomography during an in situ tensile test

Andreas Mortensen

This paper describes an in-situ tensile test in synchrotron tomography achieved for the first time with a frequency of 20 tomograms per second (20 Hz acquisition frequency). This allows us to capture rapid material fracture processes, such as that of a met ...

Microscopic strength of silicon particles in an aluminium–silicon alloy

Andreas Mortensen, Goran Zagar, Martin Guillermo Mueller, Marta Fornabaio

A microscopic three-point bending test that measures the strength of faceted particles of high aspect ratio is developed and used to probe individual coarsened plate-like silicon particles extracted from the eutectic Al-12.6%Si alloy. Focused ion beam mill ...

Composite model for predicting the punching resistance of R-UHPFRC-RC composite slabs

Eugen Brühwiler, Maléna Bastien Masse

Adding a thin layer of Ultra-High Performance Fiber Reinforced cement-based Composite (UHPFRC), with or without steel rebars, over a Reinforced Concrete (RC) slab is an efficient reinforcement method for existing structures. The thin layer of UHPFRC serves ...
