Fracture toughness of Al replicated foam

Elastoplastic toughness testing of pure aluminium replicated foam is conducted following a J-procedure adapted from the ASTM E1820-08a standard using disc-shaped compact tension specimens. Tests cover a wide range of foam relative density V-m (10-24%). Res ...

Fracture and Fatigue of Adhesively-Bonded Fiber-Reinforced Polymer Structural Joints

Ye Zhang

Being good structural replacement for other conventional material, the pultruded glass fiber reinforced polymer (GFRP) profiles are being increasingly used in civil engineering structures. The connection between components is considered the most suspect ar ...

Dislocation shielding and crack tip decohesion at the atomic scale

William Curtin

Anti-shielding of a crack tip by a dislocation is examined at the atomistic level for a simple geometry to test classical singular-crack and recent cohesive-crack models of crack/dislocation interactions. The atomistic model shows that, as an anti-shieldin ...

Mode I an II fracture behavior of adhesively-bonded pultruded composite joints

Yi Zhang, Thomas Keller, Anastasios Vassilopoulos

The Mode I and II fracture behaviors of adhesively-bonded joints composed of pultruded glass fiber-reinforced polymer (GFRP) laminates were experimentally investigated using Double-Cantilever-Beam (DCB) and End-Loaded-Split (ELS) specimens. The large speci ...

Analysis of hygrothermally induced fiber fracture in single fiber composite using fiber Bragg grating

John Botsis, Marco Lai, Joël Cugnoni

Hygro-thermal ageing of composite materials introduces a modification in the material properties of its constituents and the development of stresses that can lead to severe local damage like fracture of the reinforcing fibers and de-bonding of the latter f ...

Fracture of adhesively-bonded pultruded GFRP joints under constant amplitude fatigue loading

Yi Zhang, Thomas Keller, Anastasios Vassilopoulos

The fracture behavior of adhesively-bonded structural joints under tensile constant amplitude fatigue has been investigated. Double-lap joints (DLJs) and stepped-lap joints (SLJs) composed of pultruded GFRP laminates and an epoxy adhesive were examined. Bo ...

Mixed-mode fracture of adhesively-bonded pultruded composite lap joints

Yi Zhang, Thomas Keller, Anastasios Vassilopoulos

The fracture behavior of adhesively-bonded double- and stepped-lap joints composed of pultruded glass fiber-reinforced polymer composite laminates and subjected to axial tension was experimentally investigated and numerically modeled. Two methods were used ...

Deformation and Fracture Toughness of Two-Phase Titanium Aluminides

Nicolas Vincent Barbi

This thesis is an exploration of deformation and fracture properties of a novel two-phase α2 + γ Ti46Al8Ta (at.%) alloy featuring a "convoluted" microstructure, produced by partners within a European Union project named IMPRESS. Properties of this alloy ar ...

Multiaxial Yield and Fracture of Replicated Microcellular Aluminium

Etienne Combaz

This work addresses the behaviour of replicated microcellular pure aluminium under multiaxial stress states and in the presence of stress and strain localization sites. Processing of the foam was conducted in-house, using the replication process. The main ...

Electron Microscopy Mechanical Testing of Silicon Nanowires Using Electrostatically Actuated Tensile Stages

Reymond Clavel, Johann Michler, Jean-Marc Breguet, Dongfeng Zhang

Two types of electrostatically actuated tensile stages for in situ electron microscopy mechanical testing of 1-D nanostructures were designed, microfabricated, and tested. Testing was carried out for mechanical characterization of silicon nanowires (SiNWs) ...
