A forum to discuss courses in mechanics at all levels
We all know Euler buckling of a beam under axial thrust, but can buckling occur in an elastic structure in which all elements are subject to tensile dead loading?
We provide a positive answer to this question, see http://www.youtube.com/user/RoyalSociety#p/u/0/EKngs1vvcJU
I am opting for a reference of nonsmooth optimization methods. Does anyone know a good one?
Tensor analysis is a very useful tool for continuum mechanics as well as other courses. I wonder which book is best for me.
I have background of anvanced mathematics, linear algebra. The book should be comprehensible.
hello everybody...
can anybody tell me about, "How to neglect stresses at constraint locations?".
thanks,
g_rakesh2.
When we have stress, say in x direction, due to poisson effect, we get strain in y and z directions.
What is the reason that associated stress does not develop due to this strain in y and z directions? Is it due to the fact that there is no restraint to this strain, something similar to when free thermal expansion does not result in stress?
Notes to everyone:
Introductory Mechanics of Materials/Material Behavior
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.
In the early days of biomechanics, there probably were not many dedicated biomechanics courses and instead a regular mechanics curriculum was studied by people interested in tissues and biosystems. However, now that there are so many dedicated bioengineering programs at Universities throughout the world, it seems as though it is more likely that much of students' basic mechanics knowledge comes through dedicated biomechanics courses. This then in turn raises the interesting question of what is taught in these courses?
Hello,
I'm a student of Mechanical Engineering.I'm really struggling in Solid Mechanics.Please Help me.I have few questions.
1. What is the best and easiest book for Solid Mechanics?
2. How can learn Solid Mechanics easily?
This semester I teach an introductory graduate course in solid mechanics. Following a suggestion made by Mark Walter, I posted an outline of my course in iMechanica.
This is the first time I teach the course at Harvard, but I taught a similar course at UCSB, and an upper-level undergraduate course of similar content at Princeton. The students for the three courses have different backgrounds. At Harvard, I assume that students have taken an undergraduate course on strength of materials (tension, bending, torsion, etc.), a course on multi-variable calculus, and a course on linear algebra. I try to avoid excessive math, and try to bring out features of mechanics. (My students may disagree with me, but at least my heart is in right place.) Most students will not be specialized in mechanics, as evident from their descriptions of themselves.
