Hi, E Dan,

I have joined this side recently. It's in deed a fantastic web site, and I love it deeply.

Moment-Curvature Relation for Arches

David M. Cooper — Sun, 09 Dec 2007 09:03:20 -0500

Assuming that the beam is not loaded out of plane, the Moment-Curvature Relation for Arches may apply. It is based on Euler-Bernoulli Beam Theory (e = (Lf / Li) - 1 & s = E e = M y / I).

M = E I Dk / (1 + ki y)

M = Bending Moment about the neutral axis (non-negative)

E = Modulus of Elasticity

I = Moment of Inertia of the profile section about the neutral axis

Dk = Change in the Curvature (non-negative)

ki = Curvature of the Undeformed Arch (non-negative)

y = Perpendicular Distance from the centroidal axis (outward normal direction is positive)

Please verify if this is correct.

find it

how can i get the book?

Experimental book

wuwenwang — Mon, 26 Nov 2007 15:19:23 -0500

Is there "The Experimental Foundations of Solid Mechanics"by James Bell on WWW? I cannot find this book in Beijing, what a pity.

you are here,my boy,Cai

crack modeling

agpkd2001 — Sun, 18 Nov 2007 12:41:56 -0500

I have just strated Abaqus learning,my thesis is about cracks in pipes I want to know which part of the mannual i should read it for modeling the cracks and analysisng it?actulaay ,i want to learn it as soon as possible,so would you please let me know what is the best way for this purpose?

Thanks a lot,

Everyone is all right!

Haha, everyone in our group is OK! Dali,xinmin and zhangshuo will graduate next year.

Everyone is busy doing paper. American dishes are not fit for your taste, and welcome you

come back to pku if you have time. Haha! what is now your research topics? is it about mechanics?

Jiang Wei

Haha, how small the world is!

Everything goes smooth since I came to the US. I have two classes, one of which is the Solid Mechanics ES240 in Harvard. That's why I have to post such entries here. I like the life in Boston, and feel very happy about almost everything except the food. I miss the dining halls in PKU!!

How about you and other guys in our group? Are you all right???

A E Love's book on elasticity is freely available on Google Book

Zhigang Suo — Sat, 03 Nov 2007 14:56:01 -0400

An electronic version of this book is freely available at Google Book. Due to copyright, only early editions are available. The last edition, the fourth, published in 1927, is still under copyright protection, and does not have a full view at Google Book.

Hi,Lei Qiao! Very happy to meet you here!

jiang wei — Fri, 02 Nov 2007 13:23:01 -0400

It is unthinkable that I can meet you in iMechanics! I often come to this forum,and it is

a good place to learn about mechanics. He he! You have been to M.I.T for four months

How about you now? Best Regards for you!

Slaughter's book on solid mechanics

Zhigang Suo — Wed, 24 Oct 2007 14:04:16 -0400

It is great that you like Will Slaughter's book. He was a graduate student of Solid Mechanics at Harvard. It might not be a coincidence that you find his appraoch pleasant.

explosive

khaleghi29 — Fri, 05 Oct 2007 08:03:39 -0400

hello

please help me

i dont know how can i model explosive forming with abaqus
