Full textEruption forecasting methods are valuable tools for supporting decision making during volcanic crises if they are integrated in a global monitoring strategy and if their potentiality and limitations are known. Many attempts for deterministic forecasting of volcanic eruptions and landslides have been performed using the material Failure Forecast Method (FFM). This method consists in adjusting an empirical power law on precursory patterns of seismicity or deformation. Until now, most of the studies have presented hindsight forecasts, based on complete time series of precursors, and do not evaluate the method's potential for carrying out real-time forecasting with partial precursory sequences. Moreover, the limited number of published examples and the absence of systematic application of the FFM makes it difficult to conclude as to the ability of the method to forecast volcanic eruptions. Thus it appears important to gain experience by carrying out systematic forecasting attempts in various eruptive contexts. In this thesis, I present a rigorous approach of the FFM designed for real-time applications on volcano-seismic precursors. I use a Bayesian approach based on the FFM theory and an automatic classification of the seismic events that do not have the same source mechanisms. The probability distributions of the data deduced from the performance of the classification are used as input. As output, the method provides the probability of the forecast time at each observation time before the eruption. The spread of the posterior probability density function of the prediction time and its stability with respect to the observation time are used as criteria to evaluate the reliability of the forecast. I show that the method developed here outperforms the classical application of the FFM both for hindsight and real-time attempts because it accurately takes the uncertainty of the data information into account. The automatic classification of volcano-seismic signals allows for a systematic application of this forecasting method to decades of seismic data from andesitic volcanoes including Volcan de Colima (Mexico) and Merapi volcano (Indonesia), and from the basaltic volcano of Piton de la Fournaise (Reunion Island, France). The number of eruptions that are not preceded by precursors is quantified, as well as the number of seismic crises that are not followed by eruptions. Then, I use 64 precursory sequences and apply the forecasting method developed in this thesis. I thus determine in which conditions the FFM can be successfully applied and I quantify the success rate of the method in real-time and in hindsight. Only 62% of the precursory sequences analysed in this thesis were suitable for the application of FFM and half of the total number of eruptions are successfully forecast in hindsight. In real-time, the method allows for the successful predictions of only 36% of the total of all eruptions considered. Nevertheless, real-time predictions are successful for 83% of the cases that fulfil the reliability criteria. Therefore, we can have a good confidence on the method when the reliability criteria are met, but the deterministic real-time forecasting tool developed in this thesis is not sufficient in itself. However, it could potentially be informative combined with other forecasting methods and supervised by an observer. These results reflect the lack of knowledge concerning the pre-eruptive mechanisms

Base on the analysis both the aspect physical and non-physical, the paper emphasized on the critical factors such as historic phase, social environment, policy interference, economic system, and cultural tradition etc. . . Which constitute the foundation of the mechanisme of the housing transformation. Further more, the paper altempt to establish a new method of "morphology of habitation", as well as the framework of the theory

Full textOne of the main sources of randomness in fatigue is the presence of defects in the material. So as to establish specifications about the material cleanliness, i. E. The distribution of inclusion sizes, the relation between the defect size and the risk of failure should be established. The pioneering results of Kitagawa and Takahashi have established that two domains can be distinguished: when defects are small, the endurance limit does not vary with the defect size. Endurance models are therefore expressed within the framework of continuum mechanics. On the contrary, the size of large defects should be accounted for, which is usually done within the framwork of linear elastic fracture mechanics. When the distributions of defects are wide, an accurate prediction of the failure probability requires a unified fatigue criterion in terms of defects sizes. Therefore, a non‐propagation criterion was developed. It is based on a critical elastic distortional energy around the crack tip and includes higher order terms (Tstress) of LEFM asymptotic fields, so as to be applicable to smaller defects. This criterion responds like the Dang Van criterion for small defects and like a non‐propagation threshold stress intensity factor for large defects. The probably of failure is then determined using the weakest link theory from the statistic distribution of defects sizes. However, when defects are small, their non‐propagation threshold becomes sensitive to the local environment of the defect. Therefore, the last part of this thesis concerns the fluctuation of stresses within the microstructure and its effects on the non‐propagation threshold of defects. This “microstructural” fluctuation induces a dispersion of the non‐propagation threshold, when defects have a dimension below ten grains and then vanishes progressively with the inverse of the squareroot of the defect size, when this defect size increases

Full textThe main goal of the works carried out during this ph-D thesis consists in developing a robust numerical strategy for the simulation of the ductile tearing phenomenon occurring in thin sheets of aluminiumalloys. The selected numerical approach belongs to the class of discontinuous methods where the cracks resulting of the damage are explicitly represented as geometrical entities. Within this framework of the non-linear fracture mechanics, reaching our aim first requires to be able to simulate efficiently the behaviour of a cracked metal sheet enduring material non-linearities. This issue is handled by the mean of a continuous description of the model based on integral equations associated to their discretized counterpart relying on the boundary element method. The extension of the elastoplastic BEM formulation to general cracked media is based on the dual BEM approach. To fulfill our initial aim, the evolution of the damage parameters has to be determined from the accurate evaluation of local mechanical fields provided by the BEM code. The modelization of the damage is hence based on the uncoupled local model of Rice/Tracey which suits to the metal sheets encountered and is easily integrated into the developed C++ BEM libraries. The coupling of these two components enables the effective simulation of resistance curves for the fracture of aeronautical panels
