Finite element analysis of ground deformation due to dike intrusion with applications to Mt. Etna volcano
FEM ground deformation dike intrusion real medium
2015/9/15
A 2D finite elements study was carried out to analyse the effects caused by dike intrusion inside a heterogeneous medium and with a realistic topography of Mt. Etna volcano. Firstly, the method (dimen...
Normal-fault stress and displacement through finite-element analysis
algorithms earthquakes faults theoretical studies numerical models analytical models displacements stress
2015/9/10
We compute displacement and stress due to a normal fault by means of two-dimensional plane-strain finite-element analysis. To do so, we apply a system of forces to the fault nodes and develop an itera...
