I have a aba_gcont_pool_size error, it say's to increase to numeric number of 1 or set to high, but I don't know where this parameter is located? I looked in the abaqus.v6.evn file, and it's not in there? Does anybody know where this parameter is located?
It is essential to know the amount of springback for a given forming process, so that the process or the design of the tool can be modified to obtain the desired product shape. This requires a comprehensive understanding of loading and unloading processes, and determination of elastic constants with finite plastic deformation which, in turn, require precise determination of subsequent yield surfaces.
We call for contributions from mechanics community to 2011 MRS Spring Meeting Symposium Z: Nanoscale Electromechanics of Inorganic, Macromolecular, and Biological Systems
The abstract submission is open until Nov. 2, 2010, at http://mrsspring2011.abstractcentral.com/
More information about the symposium, including a list of invited speakers, can be found at
I have some problems with my matlab code in a 9 node shell
element each node has 5 DOFs. I found that stiffness matrix for each
element is symmetric, but after transformation to global coordinate
system, the transformed stiffness matrices and the resulted global
stiffness matrix of entire shell is nonsymmetric, where order of
transpose([k]) -[k] is approximately E-18.
Mass matrix also has
been antisymmetric after transformation and so I can't solve
characteristic equation to find eigenvalues needed for dynamic analysis.
Dear all,
Herewith I want to announc the release of CONTACT version 10.2.
The main changes with respect to earlier versions of the program are as follows:
Materials such as sedimentary rocks, pharmaceutical tablets, plastic bonded explosives, biscuits, concretes, nacre, solid propellants, seashells and asphalts can be treated as particulate composites that consist of particles of high volume fraction, matrixes of thin layer and interfaces of high specific surface area. Mechanical behaviour of highly packed particulate composites is the theme of this issue of Journal Club forum.
i want to model reinforced concrete beam and column in ansys software.i choose the same solid 70 both for steel and concrete. changed only the material properties. is it ok?
how can i model the stirrups?
if i am using the link33 for steel,how can i do it?
i am going to find the fire resistance of reinforced concrete beams and columns by including the factors required under performance based design and validating the results with real fire test values.
how we include the multilinear properties of concrete in the modelling?
There is a lot of homogenization theories based on penetrable model or some other name like 'overlapping', 'randomly imbedded model' to analyze random microstructure. In reality, the fibers or inclusions can not be penetrated into each other, so why they use this assumption anyway?
Thanks for your opinion.
