An inverse problem applied to volcanology is studied. It consists in the determination of variable pressure a crack order fit observed ground displacements. The deformation volcano assumed be governed by linear elasticity. direct solved via fictitious domain method, using finite element discretization XFEM type. misfit minimized combination decomposition and optimatily conditions. gradient cost...

This study presents calibration and validation of a cohesive extended finite element model for fatigue crack propagation in ductile materials. The approach relies on separation between plasticity around the tip growth at such that influence driving forces is predicted. implies characterization requires effective Paris parameters. It shown calibrated can capture behaviour materials in-phase out-...
