hello,

I need some examples in *.pdf to learn fracture mechanics in abaqus. the best for me will be some example for 2d and 3d stationary crack and 2d and 3d for crack propagation

Overview

This is a blog entry about my background as it pertains to solid mechanics, written in effort to achieve maximum credit for Problem 6 on the ES 240 assignment due Friday, October 5, 2007.

Prior Courses in Solid Mechanics

My prior experience in solid mechanics is limited to half a semester of graduate "Mechanics of Materials" which I took as a listener at MIT in Spring 2005.  As such, much of the material covered in this subject is new to me.

hi everybody.

 I am interested to implement  tresca failure criteria in my plastic material model (ABAQUS/standard) using UMAT subrountine which is avaiable in ABAQUS code but it is primaryly made for Mises failure , so i made few attempt to modified it for tresca , but it did not work out, so if anyone have any idea , please guide me. 

thanks

- I took one undergraduate classical Solid Mechanics course.

- Mechanical Engineering undergraduate degree (Bucknell University).

-Strengths - most of the concepts aren't new since they were introduced in undergrad solids. I've never used index notation before and it's been a long time since I took multivariable calc and diff eq. so my math is a little iffy.

-Microrobotics Lab (Woodgroup)

-Autonomous biomimetic microrobotics

help.....i am a first year undergraduate student.
how do i can design a delay switch mechanism using a dashpot.with the condition below:
a)time delay required 3seconds.Diameter at mechanism 74cm use suitable viscocity.
b)propose a refinement so that switch rate progresively slower.
so,where can i get this type of the information,how can start to do it?
thanks...

Hi everyone,

Anyone can tell me how to determine the fracture energy for crack propagation in a 4 points bending notched beam (mode I)?
