Hello, pls i need ur assistance on how to solve these problems

1) calculate young's modulus for an iron crystal when tension is applied along a <122> direction.

2) consider a thin-wall tube that is 1 inch in diameter and has a 0.010-inch wall thickness. let x, y and z be the axial, tangential(hoop), and radial directions, respectively.

(a) the tube is subjected to an axial tensile force of 80 lbs. and turque of 100in-lbs what is the magnitude of the largest principal stress?

Dear all,

To register for the CISM course on isogeometric analysis described here: http://www.cism.it/courses/C1301/ please go to: http://www.cism.it/accounts/login/?next=/courses/C1301/apply/

It would help if you applied early, to make sure there are places remaining. Talk to me if questions arise.

Fracture strain for steel in Abaqus

Submitted by Borad M Barkachary on Sat, 11/03/2012 - 10:28

Hello Everyone,

I am modeling a machining simulation in abaqus. there I have to used JC material model and Ductile damage. I am taking mateial properties for Steel specifically AISI 4140. So in ductile damage option, i need to put fracture strain value. for time being i am putting 1.5. I will be very thankful if anyone tell me the actual value of fracture strain for steel or more specifically for AISI 4140.

Thanks in advance.

regards

Borad
