Basic information about Plasticity

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.

Elastic dielectrics, slides for a short tutorial

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:

Graduate Research Supplements (GRS) to Current ENG Awards to Broaden Participation

(This message was sent to iMechanica by Ken Chong, of the National Science Foundation).  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.

3D fracture analysis using Ansys

hi,

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 

tutorial for hot deep drawing simulation

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

K value calculation in Ansys

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.

Abaqus/CAE version 6.6

 Dear all,

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.

how can apply a tightening torque

I use the abaqus present , how can apply a tightening torque between an implant (screw) and the bone with abaqus......... thank you

 

 

Differences between cohesive/interface/embedded process zone

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.

Central crack loaded with stress

Choose a channel featured in the header of iMechanica: 

1. Central crack loaded with stress.

(A) The stress intensity factor for a central line crack in an infinite plate is found to be  

 K=p(πa)^.5

 

where p is the pressure exerted along the crack line. (A) Does this formula imply a stable or an unstable crack propagation when p reaches the critical stress level? (B)  Present an experiment to support your answer in (A). Specify your experiment in details.

New (Free!) Solid Mechanics Textbook

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.

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!

Using Abaqus for orthogonal metal cutting problems

Choose a channel featured in the header of iMechanica: 

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 ,

Introduction to Cohesive Zone and Modelling DCB Test using Cohesive Elements

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?

An Introduction Course on Mechanics

 

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.

Stress concentration at a corner of varying angles, mode I and mode II

Choose a channel featured in the header of iMechanica: 

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.

Two Questions in Concrete Modeling

Dear  Friends
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?
Regards
Meisam M.
