Does anyone know of a simple book, approximately 50 pages or so, for plasticity?. I am looking for something that is similar to Morton Gurtin's "Topics in Finite Elasticty" published by SIAM. This book is an uncluttered treatment of finite deformation elasticity and was very useful for me during graduate work. I am NOT looking for 200-300 page texts, becasue I will never get around to reading them.
Rob Wood teaches a course on micro/nano robotics, and asks me to give a 30-minute tutorial on the theory of dielectric elastomer actuators (DEAs). I attach my slides, which might be useful to you if you'd like to include this topic in your class. The tutorial draws upon work in the literature, as well as recent work in my group:

This letter is to call your attention to an opportunity to broaden participation particularly of underrepresented students in Ph.D. programs in engineering through supplements to current research grants funded by the divisions in the Directorate for Engineering (ENG) at the National Science Foundation.
i m vijay doing M.TECH in aerospace, i m doing project in the area of fracture mechanics using Ansys, so i need to find Energy release release rate for 3D plate (composite plate having cracks on thikness). i want material related to this, can anyone plz send the material.
thanks in advance
I am final year student , doing my project on "hot deep drwing on non-ferrous materials" and doing simulation on abaqus . I need a tutorial ,,,,,,,,,,,please some one help
I am trying to calculate K values for a double tip crack orientated at 45 deg in a rectangular plate in ansys.I am stuck with a strange problem. When i give the Kcal command it says the crack face is not parallel to the active x axis. But i have checked the cordinates of the keypoints that i have used to create the crack. The crack is perfectly symetric about the active cordinate system about the crack tip.Can somebody help me please.
For my final year project, I've done the 3D model of a test fixture which is used for the compression testing of a specimen.
When I apply a downward vertical displacement to top Slider B, eventually the 2-slider linkage mechanism will cause the bottom Slider A to move horizontally and to compress the cube shaped specimen.

I use the abaqus present , how can apply a tightening torque between an implant (screw) and the bone with abaqus......... thank you
I am PhD student and i'm working on the behavior of bonded joints under impact and i have one question :What are the differences between a cohesive element, an interface element and a embedded process zone element ? Do they have fundamental differences or it's only a difference of the cohesive law expression.

I have posted an advanced solid mechanics textbook on http://solidmechanics.org/
It works on Internet Explorer, but may not work on all browsers. Topics include: mathematical descriptions of deformation and forces in solids; constitutive laws; analytical techniques and solutions to linear elastic and elastic-plastic boundary value problems; the use and implementation of FEA; fracture mechanics; and the theory of deformable rods, plates and shells.
Over 400 practice problems are provided, as well as demonstration finite element codes in MAPLE and (soon) MATLAB.
Please visit www.jove.com
You'll find tons of video about biological experiments you might be interested in. It is very useful for most of mechanicians who lack this kind of knowledge and experience. Enjoy yourself!
Message from Stephen W. Tsai, of Stanford University. After well received, successful completion of Composites Design Tutorial-1, we are pleased to announce Composites Design Tutorial-2 starting on April 8, 2008. This tutorial, comprising of twelve weekly 120-minute live sessions, is offered over the Internet using the cutting edge WebEx application with VoIP. The tutorial is offered to the Eastern and Western Worlds at convenient local time followed by active Q&A in English and other three languages for extended period. This allows the participants to access the tutorial contents on demand 24/7, even after the live tutorial sessions.
How do we use Abaqus to simulate the orthogonal metal cutting process and check for values of various parameters during the cutting operations ? I would be extremely thankful to anybody who could assist me on this . Tahnking You in Advance ,
I am currently working on a project to model DCB test in ABAQUS. My current problem lies in understanding cohesive zone modelling. I was wondering if anyone can forward me a couple of materials regarding the introduction of cohesive zones?
This would help me understand the material greatly and help me in modelling the DCB test.
Another question in ABAQUS: how do you implement the material properties for cohesive elements? in particular, what values should i be using for them? e.g. E, G1, G2?
We are currently offerring an introductory course on mechanics for junior students for all fields and subjects. It is a so called general knowledge course for students to know more on certain subjects and fields before a decision on choice of a major is made. Since the Mechanics Department in our University has not been popular for so long, we have decided to evangalize our field with more glorious history of Mechanics: Newton, Bernoulli, Euler, Clausius, Faraday, and Einstein.

i am a naval architect ,MSc student at ship structure.
i hope i find good ,friends,opinions in this site and be a good replier to your questions too.
I was looking at the stress concentration at a corner for both a mode I and mode II loading situation.
For reference, see: Carpenter, 1984. Mode I and mode II stress intensities for plates with cracks of finite opening. International Journal of Fracture. V. 26. 201-214. 1984.
The problem that is being addresses is the stress concentration found at a corner in an infine body as seen in the figure below. β=0...π.

I use abaqus cae for modeling and wanna know how should I attech subroutine file to abaqus cae file!
I've 2 questions:
1) I use abaqus cae for concrete modeling and how can I attech a file (subroutine/etc.) to my model?
2) which category I should use for concrete while making a part(shell/solid)? while I'm trying to make a section , only shell section have a rebar layer and solid section dont have this option! what should I do?
I have come accross an equation of the form ∂2u/∂x2 + ∂2u/∂y2 - K2 u =0 with the following conditions. y ≥αx,y ≥-αx, x=H.How to solve this equation?.analytically.
