Analysis time problem when combining UEL and UMAT

Submitted by Roche on Mon, 07/15/2013 - 16:55

Hi,

I have a model which includes damage propagation,heat transfer and effect of humidity. For damage analysis I'm using a UEL, and for the rest I'm doing a coupled thermal- displacement(CTD) analysis using UMAT and UEXPAN. The analysis starts with applying a load of humidity and temperature from 0 to a final value, and then in STEP2 I apply a cyclic load in a same range.

Dear all,

can we say that initial tangent modulus and secant modulus can be considered as upper bound and lower bound limits for uniaxial compressive stress strain curve of concrete?

If so can u show me the literature proof for that?

Thanks

Dimensional reduction

rigid coupling

hello, I am new to the forum, Hi to all

For the last couple of months I have been struggeling with modeling and coupling of 1D elements with 3Delements of a tube plate, 1D elements are chosen because of obvious reasons, we would like to reduces the mesh.
