Computer simulations will be used more and more for composites design and manufacturing. Before an engineer can simulate, there are at least two questions: what are the tools available and which one works for my problem. Thus, as a start, cdmHUB plan to compile a list of micromechanics codes for the community, including commercial codes, public domain codes, or research codes. To make the list as complete as possible, we need your help.
One can now run GEBT (Geometrically Exact Beam Theory), a general-purpose nonlinear composite beam solver, online within a web browser through cdmHUB.org. Users do not have to install the code on their own machine. And users can access to immediate support if run into any questions. You are welcome to try out the code and let me know any of your questions.
I am teaching mechanics of materials to sophomore. However, our students do not have a separate static course. They get a some exposure to free body diagrams in particle dynamics. I am currently using the book by Gere and Goodno. But I found that both the teaching and learning experience were not good. Thanks a lot in advance for your suggestions!

Attached is part of my lecture notes for a graduate structural mechanics. In
the notes, we derived the classical plate theory, which is also called
the Kirchhoff plate theory, in three ways: Newtonian method, variational
method, and variational asymptotic method, using 3D elasticity theory as the
starting point. The self-contradictions of Kirchhoff assumptions and plane-stress assumptions used in both
Newtonian method and variational method are clearly pointed out. The
After having taught graduate structural mechanics for several years, I am finally
able to write down my lecture notes (attached) for teaching the beam theory. In
the notes, we formulated the complete classical beam model
(extension/torsion/bending in two directions), which is also called
Euler-Bernoulli-Saint beam theory, in three ways: Newtonian method, variational
method, and variational asymptotic method, using 3D elasticity theory as the
starting point. Many self-contradictions of the various assumptions used in both
Newtonian method and variational method are clearly pointed out. The
I am writing to let you know the release of VAMUCH 3.0, the 3rd version of our general-purpose micromechanics code. The main new features are:
Dear All,
I am looking for highly motivated PhDs/PostDocs to join my group to work on various aspects of efficient high-fidelity modeling of composite structures/materials, mainly related with VABS/VAPAS/VAMUCH. The basic qualifications are: basic training in solid mechanics and composite materials, excellent math and programming skills, and good English communication skills. Please let me know if you are interested or if you know somebody is interested.

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:
