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

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.
As a journal editor, I am often surprised by some of the suggestions authors make for potential reviewers. In some cases the suggestions are not very good, and on occasion authors do not suggest reviewers at all. Some authors will even state explicitly that they cannot think of any reviewers, which is really surprising.

The 16th in a series of conferences, starting in Delft in 1959 and following on from the last conference in Porto in 2012 this is the premier event to showcase novel and innovative research in Experimental Mechanics. The conference will take place in Cambridge with the accommodation at Robinson College and the technical sessions at both Robinson and the West Road Concert Hall.
Dear sir,
I am modeling ligament structures in the knee joint finite element model
with non-linear springs and I am successfully getting non-linear
displacement curve.
My only problem is with the calculation of tension in the springs. I
have a set of non-linear springs representing a particular ligament in
the joint, which is having an elongation when I apply the forces on the
joint. I am giving pre-load to the springs so that they do not have any
slack in them before the analysis. I am also specifying the stiffness of
One Ph.D. student position is available at the Centre for Innovative Structures and Materials RMIT, University. The research topic is about computational mechnaics and structural topology optimisation. It is expected to enroll in the end of this Auguest. More details please contact with e89817 [at] rmit.edu.au
