Dear All,

All,

I am writing to introduce DNAD, a Fortran module I wrote for automatic differentiation of analysis codes written in Fortran including those legacy codes written in Fortran 77. Although only implementation using Fortran 90/95 was carried out, it is straightward to translate it to a language you like such as c/c++.

Dear All,

I am writing to introduce to you a general-purpose composite beam solver, GEBT, which can capture all the geometrical nonlinearity obtainable by the six fundamental deformation modes (extension, torsion, bending in two directions, and shearing in two directions), and the coupling between these fundamental deformantion modes, such as extension-twist coupling commonly existing in initially twisted rotorblades. The features of GEBT are:

1. GEBT can analyze any structure which can be modeled as an assembly of beams made of arbitrary material and arbitrarily oriented in the 3D space.

There is a very strange problem puzzled quite a few in the rotor blades (including helicopter blades and wind turbine blades) community. We hope some mechanician on this board can help us explain the situation.

I am looking into object oriented programing of the finite element method. I don't know whether somebody can provide a general-purpose oop design of a general finite element program, say a linear static analysis of a 3D solid. Or somebody who are experienced in this field point out some good references for this purpose. It will be better if the oop design is language free, i.e. not directly related with implementation in a specific language such as c++. Thanks in advance.

I am glad to introduce VABS, a unique software tool for modeling of composite structures having one dimension much larger than the other two dimensions such as helicopter rotor blades, wind turbine blades, HALE wings, and bridges.

Dear Fellow Mechanicians:

 If you know somebody (including yourself) are looking for faculty jobs, please encourage them to apply to Utah State University. We are filling two tenure-track positions in the broad sense of solid mechanics or thermal science. At least one position for solid mechanics. For details of the job descriptions, please refer to my previous post. You need to apply through the online system at jobs.usu.edu. We will start reviewing the applicants on January 7th, 2008.

Best regards,

This is Wenbin Yu from Utah State University, more details can be found from my website (www.mae.usu.edu/faculty/wenbin). I browsed through this site several times and felt like home here, particularly seeing so many of my friends  and so many of my role-model mechanicians. I finally made the decision to register and became part of the iMechanicians family.  Zhigang, thanks a lot for providing such a wonderful platform for mechanicians to network and exchange their ideas. This post may not belong to the research channel. I am just try to see whether I can post.
