Fatigue monitoring of glass fiber reinforced composite using fiber Bragg grating

Glass fiber reinforced composite (GFRC) are widely used in all load bearing industrial applications. It is therefore critical to understand the fatigue characteristic of GFRC to improve the material characteristics of these composites and to prevent any untoward accidents. In this paper we describe the preliminary results of fatigue test on GFRC fabricated using an in-house laboratory scale resin transfer molding system. The fatigue tests are done for different load conditions – tension compression and reverse bending. Fiber Bragg grating (FBG) is embedded into the composite at the manufacturing step for monitoring the strain. The preliminary results of these experiments are presented

Study of local and transient buckling in glass fiber reinforced composite using fiber bragg grating

Many models encountered in computer science remain intractable because of their tremendous complexity. Among them, the numerical modeling of manufacturing processes involving several characteristic times is a challenging issue. Classical incremental methods often fail for solving efficiently such transient models. In that sense model reduction based simulation appears to be a very promising alternative. Multidimensional parametric models can be solved within the context of the Proper Generalized Decomposition (PGD). It opens new horizons regarding time parallelization. Indeed, by no more considering the initial condition of a transient problem as a static input data but as an extra- coordinate similarly to space and time, we demonstrate that it is possible to parallelize efficiently the computation and even reach real-time in some cases
