Does anyone know if there is a way to simulate mechanical shocks?

yeah, learn to model in pro-e and purches all of the analitical plug-inns or simply work in unison with engineering throught the design process.

Ahh-so Pro E allows you to test this?
I am a SolidWorks guy.

You can bring a 3d model of the object in question into pro mechanica/ansys/cosmos/sdrc-ideas or some other CAD analysis package. Apply an analysis mesh and the material to the model. There are various types of mechanical analysis that can be performed at this stage.
For example, to test the impact strength, you could draw a vector path from a point in space to the object, model an impacting object and have it travel along the vector path at a given velocity until it strikes the object to be tested. This motion can be repeated until the object being tested shows fracture, deformity or some other weakness. This is basic FEA/FMEA : apply force until change, then report change.

There are various machines that are used to test shocks and mechanical properties like tensility, torque, yield strength etc. Some laboratories have these and will test the product for you, like these guys : http://www.environlab.com/

solidworks 2003 and 2004 come with ComosExpress, which is a fairly usedful FEA package. As far as simulating shock (I assuming you mean a collision of some sort) you will need a more sophisticated package.
You could however calculate the load at impact and use this to model the item being impacted.

By the way FEA and FMEA are two very different things.
