Non-local damage mechanics with evolving interactions for modeling quasi-brittle materials : anisotropic damage and gradient-enhanced Eikonal approach

Predicting the cracking nucleation and propagation is essential to describe structural response under complex loading conditions. Diffuse micro-cracks are observed to appear before coalescing into a macro-crack. In the case of quasi-brittle…

Mechanism-based modelling of the viscoelastic response of a unidirectional composite ply: validation of a new transversely isotropic model through analytical and numerical homogenisation

The viscoelastic response of long fibres, polymer matrix composites is mainly due to the deviatoric response of the matrix. This single microscale mechanism, however, results in different amount of viscous relaxation for the elastic constants…

Mechanical identification with the reconditioned equilibrium gap method: Formulation, analysis and comparisons

Full-field measurements are used to calibrate material parameters. The Equilibrium Gap Method (EGM), like other identification formulations that use full-field data, has the advantage of being direct for linear behavior and some nonlinearities,…

The liquid metal embrittlement of a reactive system at room temperature: α-brasses in contact with the liquid eutectic Ga-In

We studied the liquid metal embrittlement (LME) at room temperature of α-brasses by the liquid eutectic Ga-In (EGaIn). The EGaIn partially wets the α-brasses and forms the CuGa2 intermetallic. 3-point bending tests, Finite Element Analysis, and in…

Identification of fracture properties at the interface between CMC and EBC at room and high temperatures using full field measurements

The objective of this work is to predict the lifespan of CMC/EBC systems by quantifying interface damage and estimating the interface adhesion energy. Four-point flexural tests were conducted at room temperature and 1000°C. These tests initiated…

DEVELOPMENT OF AN INTRALAMINAR SHEAR FIXTURE FOR THE TESTING OF COMPOSITE SPECIMENS OUT OF THEIR ORTHOTROPY AXES

The design of innovative ceramic matrix composites parts requires a precise characterization of the materials to avoid oversizing costs. Several methods already exist to characterize the shear properties of composite laminates, classically the…

Crystalline / glass nanoscale chemical separation induced by femtosecond laser pulses in aluminosilicate glass

An aluminosilicate glass with a molar composition of 60%Al$_2$O$_3$–40%SiO$_2$ fabricated by the aerodynamic levitation technique was irradiated in volume using an infrared femtosecond laser. Optical retardance was observed and measured upon a wide…
