Hi all!

I am trying to simulate the tensile test in ABAQUS. Could you please tell me how I can incorporate the power hardening stree strain relation in ABAQUS?

Thanks in adavnce

The April issue of the IEEE Spectrum featured the recently re-named Harvard School of Engineering and Applied Sciences, and the man who made it happen:  Dean Venkatesh “Venky” Narayanamurti.  With incredible energy and ingenuity, Dean Venky has been leading his colleagues to build up Engineering at Harvard.  He has to answer obvious questions:  How would Harvard make a mark in engineering with the mighty Massachusetts Institute of Technology just down the street? And why would Harvard, essentially a liberal arts college, want to do engineering anyway?  To learn about the man and his answers, read the Spectrum article.    The Harvard School of Engineering and Applied Sciences has been the host of iMechanica. 

What are the good books to refer for thermal analysis with practical applications.

Does the FEM software（ ANSYS，abaques，et al） ues the isoparametric element  concept?

 Thanks for your reply。

hi friends

i have problem in full transient analysis in ANSYS 11.0

kindly give me solution.

i have data .....

BEAM FOR IMPACT LOAD 

lenth=144 inch 

area=120 sq inch 

moment of inrtia=1000 inch rest to four

depth=10 inch

elastic modulas=3605 kips per sq inch

density of material=8.6805E-5  kips per cubic inch

FOR SOLUTION..(force 23.8 kips is linearly decreases from time = 0 to 0.042 at centre of the beam)

at time = 0 sec , force = -23.8 kips

at time = 0.042sec , force =0 kips 

time increament = 0.002 sec 

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.

Does anyone know how to calculate the stress concentration at the corners (a change in angle of a straight line)??? if you do, could you explain it to me and present equations.

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 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.

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 

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.

 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.
