I Have got a problem. I am trying to replicate of finding out "Natural frequency of the I-40 Bridge over Rio grande" results which was done and reported by C.R.Farrar et al. I tried the way he proceeded but not matching with the results I got from Abaqus.
Composites reinforced by thinner fibers are intensively studied in recent years and expected to have better
mechanical properties. With development of nanotechnology, the diameter of fiber can be as thin as
several nanometers, such as nanofibers and nanotubes. Then, do these thinner fibers definitely result in
composites with better mechanical properties? In this paper, the toughening effect of reinforcing fibers in
composites is investigated based on the three-level failure analysis model. It is found that thinner

I am doing my research in nonlinear vibration of beams. In that research, I have to derive the shape function for different end conditions of the beam. Regarding this,I need some ideas. Are there books I can reference?
Regarding my research work, I need to know about hermite cubics in Fem. Can any one suggest a book regarding this?

Abstract
Hello everyone,
I have modeled compression test on concrete cube in Abaqus/Explicit. For concrete I have used Concrete damaged plasticity model. I have assigned displacement as BC (Smooth amplitude) in Reference Point at the top of the cube, and I have coupled RP with the top of the cube. For concrete cube I have used C3D8R elements.
For history output I have requested Reaction force in RP and energies for whole model.
But job won't finish. I get an error:
I have one model offshore that were designed based on BENTLEY SACS and by that I wanted to convert it on LS-Dyna or SACS to CFD to observe blast and fire effects & loading and then for non linear analysis of structural.
