“…Such asymptotic approaches are very convenient in the case where the thermophysical properties mapping is slightly varying versus mechanical stresses. The result shown in the figure 7 was used for Ceramic Matrix Composite (CMC) characterization (see [10]). In the next section (application to microfluidic devices), an other strategy is proposed.…”

Generally the IR images are related to the transient temperature field related to the emission of a black surface in response to an external or internal heating (active IR thermography). At I2M-Bordeaux, the first applications were devoted to the so called thermal Non-Destructive Evaluation methods. But with simplified assumptions related to the transverse diffusion, the in-plane diffusion and transport phenomena can be also considered and applied to microfluidics or multispectral detection. There are a lot of possible strategies to process the big amount of temperature data (previous integral transformation of the images, compression, elimination of the non useful areas…), generally based on the necessity to analyse the derivative of the temperature field versus space and time.

To accurately determine the temperature-dependent parameters of composites, a thermo-elastic parameter identification approach using thermal modal data is proposed in this article. The investigation is based on two hypotheses: (1) the structure is at steady-state temperature field, which means the temperature distribution is time independent; (2) temperature distribution can be determined in advance of thermo-elastic parameter identification, and thermal-related large deformation is not considered. The thermal-dependent elastic constants and thermal expansion coefficients are expressed as intermediate functions with the independent variable of temperature, perturbation method is adapted to calculate the sensitivity of thermal modal frequencies with respect to the intermediate variables, and variables with high sensitivity are selected as the identifying parameters. By constructing the intermediate function and calculating the relative sensitivity, thermo-elastic parameters are identified by minimizing the residual between experimental and analytical natural frequencies under thermal circumstance. Two different types of composite models are employed to verify the strategies of parameter identification. Results show that on the basis of the intermediate function, the proposed approach can be applied to identify the thermo-elastic parameters effectively.

“…This nonlinearity is caused by the development of significant matrix cracking [9], while the propagation of damage is resisted by the 'fibre pull-out' toughening mechanism from the continuous, high-strength SiC fibres [10,11]. Micro-cracking damage also affects the heat transfer properties of the cladding [12].…”

The problem of multi-scale modelling of damage development in a SiC ceramic fibre-reinforced SiC matrix ceramic composite tube is addressed, with the objective of demonstrating the ability of the finite-element microstructure meshfree (FEMME) model to introduce important aspects of the microstructure into a larger scale model of the component. These are particularly the location, orientation and geometry of significant porosity and the load-carrying capability and quasi-brittle failure behaviour of the fibre tows. The FEMME model uses finite-element and cellular automata layers, connected by a meshfree layer, to efficiently couple the damage in the microstructure with the strain field at the component level. Comparison is made with experimental observations of damage development in an axially loaded composite tube, studied by X-ray computed tomography and digital volume correlation. Recommendations are made for further development of the model to achieve greater fidelity to the microstructure. This article is part of the themed issue 'Multiscale modelling of the structural integrity of composite materials'.
