Book recommendation (Structures under impact)
(OP)
Hi,
Can anyone suggest some books for structures under shock and impact? (for example designing a steel plate impacted by a bullet.....which text should i use to learn about designing such structures?)
Thanks,
Mike

RE: Book recommendation (Structures under impact)
About the only direction I can give you is the textbook Fundamentals of Machine Component Design by Juvinall and Marshek. It has a 25 page chapter on impact. There are also a couple of papers referenced by this chapter:
Rinehart, John S., and John Pearson, Behavior of Metals under Impulsive Loads, The American Society for Metals, Cleveland, 1954.
-and-
Vigness, Irwin, and W.P. Welch,Shock and Impact Considerations in Design, in ASME Handbook: Metals Engineering--Design, 2nd ed., Oscar J. Horger (ed.), McGraw-Hill, New York, 1965
Let me know if any of these sources help you. I have never needed to design for impact, but am interested in the topic.
Good Luck.

RE: Book recommendation (Structures under impact)
d(impact)/d(static) = sigma(impact)/sigma(static) = SQRT((v^2)/(g*d(static)))
Where:
d(impact) = deformation under impact load
d(static) = deformation under static load
sigma(impact) = stress under impact load
sigma(static) = stress under static load
v = velocity of impact
g = gravity
This equation applies to a horizontal impact as in your bullet/ plate case. d(static) and sigma(static) are the deformation and stress the weight of the moving body would produce if applied as a static load in the direction of the velocity of impact.
This equation assumes no kinetic energy is disipated by the impact which is untrue and adds to the conservative nature of the equation.
This can be found in Roark's Formulas for Stress and Strain.

They have written a subroutine for composite materials for LS-DYNA, and undoubtedly have the analytical basis for their impact solution. LS-DYNA publications probably explain a lot as well.

I worked in the military marine industry for several years. I didn't do much in the way of armor piercing calculations, but I also never saw this website...good one!

Lots of good stuff! Do you know if there's been any correlation of the programs against current RHA steel or titanium armors?

It wouldn't surprise me if http://www.tank-net.org/ had some good resources on more modern armor.
