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.

Major History

- 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

To all students in ES 240 this semester,

Due to popular demand my office hour is moved from Tuesday to Thursday 4~5pm starting from this week. The location is changed to Rm. 123, Maxwell Dworkin (33 Oxford Street).

Prior courses in solid mechanics: "Mechanics of Solids and Structures" was FBD's and strength of materials, and "Special Topics in Mechanical Engineering" focused more on building and aerospace structures.  But no prior solid mechanics course, per se.

Undergraduate major: Engineering, concentration in Materials Science

The assessment includes:

• Final exam (70%)
• Lab (10%)
• Two take-home assignments (each worth 5%, total 10%)
• Lecture-notes (10%)

Assessment results will be not be posted online. Online activities are for discussions only, no grading based on that. The first course-assignment will be given in 19/10, Friday.

This problem set will be due on Friday, Oct. 4th.

Part 3 of Elements of Elasticity. Please see attached.

This problem set is due on Friday, Sep. 28, 2007 in class.

The lecture notes are prepared by Prof. Joost Vlassak based on a set of course notes put together by Prof. Suo when he taught ES 240 in 2006, as well as on course notes developed by Prof. Vlassak for ES 246.

 I am dong project on strain energy release rate of four point bending  load can anyone suggest me how to calculate strain energy release rate using ansys

Hello! I am a new comer in this forum. I am a Mechanical Engineer. Now I am Looking for my M.Sc. in applied Mechanics & Design. My two subjects in this semester are THEORY OF PLASTCITY & EXPERIMENTAL STRESS ANALYSIS. Please anyone of you having notes or books in soft form please post for me. Thanks

I am Dhaneshwar Mishra, currently a PhD student at Ajou University, South Korea. I am working in the area of Bimaterial Fracture. Currently i am trying to calculate Stress Intensity factor of cracked bimaterial plate. I wanted to use Interaction Integral Method to seperate Complex stress intensity factor.

Will some one please through light on use of interaction Integral Method used for cracked bimaterial interfaces.

Hope to receive early suggestions.

Thank you.

With regards

Hello students (and also others) at iMechanica,

Last weekend, while channel browsing on TV, I happened to notice a documentary on the Hoover dam (in the US). It showed a number of jets of water, huge ones, forcefully springing forth out of the rock faces just downstream of the dam. These were the water jets coming off the electricity generation plant of the dam, *after* their job of generating electricity was already over.

Can you help me

Iam studying ansys

for model facture mechanic

Hi,

I am a PhD student and I have just started to work on FEMLAB and was just wondering if someone could help me with FEMLAB. I am using at the moment the PDE modes-Weak forms to solve flow over topography using the lubrication equation. I have implemented the lubrication equations into the subsomain settings and set the boundary conditions  but i do get wrong results. Could you please advice where i might have done wrong.

Any suggestions will be really appreciated.

Many thanks

Catherine

Hello all,

I am new to this. I got a couple of good inputs from this site, so I thot I would join too. I am a PhD student in Clemson univeristy. I am using ABAQUS for my research. Let me get to the question quickly. There are two variables that you can define in a user subroutine called TOL and HTOL. What are these and how can I know more details about this. Any inputs will be appreciated.

Thanks

I came across this web page recently, and it talks about a novel product d3o that can control impact effects by adjusting molecular structure in case of shock loads. If this material becomes a regular apparel material, we may see many Jackie Chans in the future. The material is d3o.

Visit this page to learn more about this material, This is not a SPAM. http://www.d3o.com/index.php

I don't know if you guys knew of this. I guess you do. Is this material really the way it is advertised, or some boasting included?

Recently, I have seen a quit interesting article as follow:
