Numerical analyses of low velocity impacts on composite. Advanced modelling techniques - 2012

In this paper the most advanced features currently available in FE analysis (Abaqus/Explicit) have been used to predict the behaviour of a composite structure under low velocity impact. A low velocity impact event on a flat composite plate has been evaluated. The plate has been modelled using solid elements for each composite layer and a user defined material model with a modified Puck failure criterion was implemented.

Hydrodynamic Pressure on Culvert Gates during an Earthquake - 2012

These gates are designed to withstand the hydrostatic and
transient pressure loads. A phenomenon that is, however, usually overlooked in the design is the hydrodynamic pressure that is built up in the system during an earthquake.

Dynamics of a Completion String in a Fluid Filled Wellbore - 2012

The mechanical manipulation of the equipment, however, can induce significant sudden movement of the completion tubing string near the tool’s locking mechanism. The rapid movement of the tubing string causes large relative motion and “piston effect” forces between tool components and fluid present in the wellbore.
