Residual stress characterization in a single fibre composite specimen by using FBG sensor and the OLCR technique
The purpose of this thesis is to characterize internal strains in polymeric materials due to consolidation. In view of this, optical Fiber Bragg Grating sensors are an excellent non-destructive tool for internal strain characterization and damage detection ...
EPFL2006Constitutive behavior and fracture properties of tempered martensitic steels for nuclear applications
In this study, the tensile and fracture properties and the microstructure of the reduced-activation tempered martensitic steel Eurofer97 have been investigated. This technical alloy is a 9%Cr steel developed within the European fusion material research pro ...
EPFL2006Microstructure and embrittlement of leaded copper alloys
Mechanisms responsible for the embrittlement of leaded "free-machining" copper alloys at intermediate temperatures (i.e. around 400 °C) are examined using a combination of microstructural and mechanical characterization. Tensile tests are conducted on pure ...
EPFL2005Consolidation and deconsolidation in composite processing
In composite processing, a compressible dry fiber preform is in many cases impregnated by a molten polymeric matrix. The impregnated part is sometimes used as produced, but most often it requires a reheating step before stamping, flow molding or even paint ...
EPFL2004Failure of crossply ceramic-matrix composites
The fast-fracture and stress-rupture of a crossply ceramic-matrix composite with a matrix through-crack are examined numerically to assess the importance of fiber architecture and the associated stress concentrations at the 0/90 ply interface on failure. F ...
Wiley-Blackwell2002Multiscale modeling of failure in metal matrix composites
A multiscale approach to composite failure, in which detailed information on small-scale micromechanics is incorporated approximately yet accurately into larger-scale models capable of simulating extensive damage evolution and ultimate failure, is applied ...

A multiscale approach to composite failure, in which detailed information on small-scale micromechanics is incorporated approximately yet accurately into larger-scale models capable of simulating extensive damage evolution and ultimate failure, is applied ...
2001Tough-to-brittle transitions in ceramic-matrix composites with increasing interfacial shear stress
The possibility of decreasing ultimate tensile strength associated with increasing fiber/matrix interfacial sliding is investigated in ceramic-matrix composites. An axisymmetric finite-element model is used to calculate axial fiber stresses versus radial p ...
2000Modeling brittle and tough stress-strain behavior in unidirectional ceramic matrix composites
A new simple model for predicting the uniaxial stress-strain behavior of a unidirectional ceramic matrix composite. including stochastic matrix crack evolution, stochastic fiber damage and ultimate failure, is presented. The model demonstrates an important ...
1998Criteria for crack deflection/penetration criteria for fiber-reinforced ceramic matrix composites
Deflection of a matrix crack at the fiber/matrix interface is the initial mechanism required for obtaining enhanced toughness in ceramic-matrix composites (CMCs). Here, energy, release rates are calculated for matrix cracks that either deflect or penetrate ...
