    Test Lab for modal analysis?

    Looking to do modal analysis on a hand-held structure in an effort to reduce uncomfortable vibration for the user - think baseball bat and the stinging sensation when mishit. Ideally, we'd be able to quantify the amount of damping (and therefore "sting reduction" for the marketing folks) from...

    Book recommendation? Impact dynamics

    Looking for a good textbook on impact mechanics - ideally covering both ductile and brittle metals as well as polymer impact failure theories. Bonus points if it covers a bit of impact failure with composite materials (carbon composite, fiberglass, etc.) as well! Anybody have any good...

    Tube dynamic dent/crush equation?

    I'm working with structural metal tubing (of an elongated octagonal cross section (height is about 17% taller than width) that's subject to high enough radial impacts (generally with another tube of similar size and strength) to cause both denting (generally on the edges), usually only small...

    Computer suggestions for Simulation (Nonlinear)

    We're shuffling some older computers out, and since I'm first in the "power user" pecking order (being the only FEA user), IT has suggested that we pass my current computer to one of the other heavy solidworks users and get a new workstation for me. I'm not about to argue, even though my...
