The Koiter-Sanders-Budiansky bending strain measure and a nonlinear generalization
We know from strength of materials that non-uniform stretching of fibers along the cross section of a beam produces bending moments. But does this situation necessarily correspond to a 'bending' deformation? For that matter, what do we exactly mean kinematically when we talk about a bending deformation?
I had prepared this document for a class project, the level is introductory and the selection of models is motivated by solder deformation, but I hope it is of some help. I have examined four models, proposed by Hart, Anand, Krempl and Busso. The document has 16 pages.
Thanks,

PS: This is a wonderful website!!!
When you first start learning finite deformation plasticity, you will run into a plastic flow rate that can be derived from a flow potential such that

whereis the Cauchy stress. For an isotropic material with scalar internal variables, the plastic
flow potential can be assumed to have the form
Most departments of Mechanical Engineering, Civil Engineering, and Aerospace Engineering have a required course called variably "Strength of Materials", "Introduction to Solid Mechanics", etc. In most departments, the content of the coure is mainly about static, elastic deformation of rods, shafts, beams and columns. It might be a good idea to share your thoughts on this course.
I am looking for a high resolution isochromatic photograph showing the
Mode II stress field around a stationary crack. Any help on

Nowadays, we often use the tools of computational analysis in engineering design. For the results of such analyses to be believable, the tools that are used have to pass rigorous tests. There are two categories of tests involved:
An interesting blog discussion on the disappearance of fundamentals from teaching in Universities was brought to my attention. It serves as an interesting reminder that we who are educators in the University system must be ever vigilent in planning mechanics curricula and changes to curriculum. Should we be offering courses in the area of this month's jClub, "Nanomechanics"? Should we drop classical courses that have stopped being interesting to the majority of students (and thus attract low numbers)? Should we educate students explicitly in biomechanics without providing them a classical mechanics background? These are the questions we are likely to face in the next few years as change continues to sweep across the university system, especialy in the US but elsewhere as well. I believe that we as a community have a responsibility here to ensure that the high standards of the discipline are maintained through teaching of fundamentals and the passing along of these values to future generations!
