I
am able to create a sphere using a 3D shell geometry, but I am unable
to uniformly mesh it. All I can see is an irregular mesh with
quadrilateral elements. I wanted to use hexahedral elements for the
sphere with uniform meshing and I tried using 'create bottom - up
mesh', but of no use.

Sorry guys, I know I've done it a long time ago. Can't figure it out now. Please help.

Hello Everybody

I am in need of help in including multiple load step options in my c program which is a fem solver for contact(2D).

I do not understand how to go for second load step after the 1st one.

Its not clear for me what all i have to do, one thing i know is updating the nodal locations.

Please help me on this or guide to the place where ir can get help.

Thank You

Plasticity

Hi all,

I doing modelling on soft clay behaviour which exhibit softening behaviour during constant strain loading. Here i followed a non-associated flow rule for better prediction of dilation . For the case of non-associated flow rule yield function and plastic potential function should not same i clear in that , my doubt is that we can use two different surface for yield and plastic potential function (eg: linear surface as yield surface and elliptical surface as plastic potential )?

torsion

Hello,

I am trying to derive/find an analytical expression
for the torsion of a round bar made of an heterogeneous material. But I just do
not seem to find any solution available in the literature other than for a
homogeneous material, which can be find in any theory of plasticity book (e.g.
Theory of Plasticity, 3rd Ed., J. Chakarabarty, pp. 132-136).
