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.
Hi all,
I am new at subroutine and abaqus requirements and its compatibility. I am trying to use a subroutine VUHARD for the material modeling of polycrystalline material under shock loading. I am not sure if I can use VUHARD because of my lack of experience in subroutines. I have couple of questions listed below and I would really appreciate if anyone can give me a insight in this subject.
1) Can I use visco-plastic formulation (rate- dependent) in VUHARD?
Dear Abaqus user,
Could be of interest for some of you.

Finite element method (FEM) with fixed representative volume element (RVE) encounters some difficulties in simulating the periodical postbuckling behaviors of infinite long beam or infinite large film on soft substrate under compression, because the wavelength and pattern of buckling are not known before simulation and will change with the increase of compression strain.
Dear all,
I am working in my under-graduate thesis. Basically, i'm trying to calculate the SIF and J-Integral for semi-elliptical surface crack using CINT command in ANSYS APDL (all of this in a pipeline model). I have seen one paper shows SIF's distribution along the crack front like the following picture (fig. 8):
In my analysis I have obtained the following distribution (I have used a/c=0.5 with a/tc and tc/Rc equal to the fig. 8):
