Cellular Automata for Multi-scale Fracture
Could cellular automata be used to model mechanisms (for quasi-brittle fracture) that occur at the meso-scale and then feed these mechanisms to a macro-scale finite element model? Is it possible to replace constitutive models with mechanistic models, simulating mechanisms that lead to fracture instead of formulating equations that predict failure? These are typical questions that have motivated my recent collaboration with Dr Anton Shterenlikht at the University of Bristol.
CONSTITUTIVE MODELS FOR STRONGLY CURVED BEAMS IN THE FRAME OF ISOGEOMETRIC ANALYSIS
The current development of the isogeometric approach in various fields of mechanics is explained by the high-accuracy results which can be achieved at a reduced computational cost by codes based on non-uniform rational B-splines (NURBS). In the case of strongly curved beams the simple diagonal de Saint-Venant’s constitutive model can lead to significant errors as it has been reported in the classic literature. Other models such as Winkler’s have been proposed and seem more suitable for these kinds of structures.
PhD Robust Optimization Viscoelastic Sandwiches
Visco-elastic structures are widely employed for vibration damping. Nowadays, optimal design of these structures has become commonplace. However, operating conditions introduce variability in their performances. Taking into account this variability in the optimization loop is necessary to obtain optimal robust solutions. Recently, within an exploratory project, supported by CNRS, the modal stability method (MSP) has been applied with success to quantify variability of damping and natural frequency of frequency dependent viscoelastic sandwich structures.
