Hello,
I am trying to solve the global stiffness matrix for a component assumed to be a series of 3-D beam elements.
Some of the diagonal elements of the transformation matrix are zeros and i eventually end up in finding the inverse of a matrix with some zeros in its diagonal which is not possible.
Can anyone let me know if the transformation matrix can have zeros along its diagonal?
Thank you.
The Department of Mechanical and Nuclear Engineering at The Pennsylvania State University is seeking applications for an Assistant Professor position in Mechanical Engineering. The position is open for highly-qualified individuals performing research in technical areas that support our multidisciplinary mechanical engineering curriculum. Priority will be given to applicants with strong background or potential in experimental or computational approaches for biomedical systems or components. The ability to merge mechanical engineering (e.g., solid and fluid mechanics, design, acoustics, heat transfer) concepts with biomedical (e.g., bio-mechanics, imaging, implants and prostheses, microdevices) applications is highly desirable.
Mimics 14 comes with a CAD-like functionality, enabling you to design directly on anatomical data.
Leuven, Belgium, October 4, 2010. Materialise NV, the world leader in software for 3D medical image processing, announces the release of Mimics 14. This release integrates ‘digital’ CAD, allowing fast and accurate design of e.g. implants and surgical guides, starting from a patient’s CT or MRI data.
hi all
pls help me to model reinforced concrete beams and columns in ansys to find the fire resistance of these members .
if u have any papers send me in my id smithappvikas [at] gmail.com (smithappvikas[at]gmail[dot]com)

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.
