Why do we often use Jaumann rate instead of Truesdell rate?

In the attachment, we show that Truesdell rate can by simplified to Green-Naghdi rate by assuming F .=. R and can be further simplified to Jaumann rate by assuming W .=. R(.)R(T), where .=. means approximately equal

TWO MECHANICAL ENGINEERING FACULTY POSITIONS IN CHILE

The University of Chile invites applications for two full time faculty positions in Mechanical Engineering. Applicants must have deep interest in undergraduate and postgraduate teaching, as well as the purpose to conduct long term, externally funded research programs at international level. Candidates are also expected to maintain fruitful work relationships with industry in their respective areas. According to qualifications, they may be ranked at the Assistant or Associate Professor level. Candidates are sought in two areas:

  1. Energy: Research interests in conventional or alternative energies, with emphasis in energy conservation, generation or efficient use.

Simulation of Metal cutting using Abaqus

Hi,

I am a research scholar. I want to carryout my research work on metal cutting. Pls let me know how can I start working with ABAQUS to get the simulation of metal cutting.

Elasto-plastic theory - ABAQUS

Hello,

 

I have started to study the plasticity theory few months ago. I'm trying to do one exercise in plane strain of one elasto-plastic material in ABAQUS and manually.

When the load is small, the material has just deformed elasticly and the total and elastic strain in z-direction (E33 and EE33) are zero (like say the theory of plane strain).

nonlinear buckling of plates

hi all,

   thanks lot, actually how to solve nonlinear buckling analysis?

1.what is the adavantage of nonlinear analysis,will u get new critical load or same value of linear buckling load?

2.one of the imechanica member suggested the follwing code,i done using tha t code but what ever im giving time value same value getting after converging my solution.

Here is the code that I used to perform the analysis:

新技术无力测试损检测残余应

新技术无力测试损检测残余应

导言

内部压力,也应视为如下: 1 )业务株提到负荷的材料是受计算2 )残余应力引起的材料热处理或强调造成的焊接,锻造,铸造等方面的新技术能够衡量载荷和残余应力的平衡表面的材料,并在一个比较大的音量,有时甚至相同的大小作为整个结构。这强调的是部分金属的弹性场和有三个轴的空间取向。

描述

Please give me some insight to develop crack bridging user element in Abaqus

Dear all

 I am trying to model damage at the interface of Dentine and enamel. AS the property of dentine material crack grown in the area of Dentine Enamel Junction(DEJ), when comes to dentine region,it start arresting due to prescence of collagen and mineral fibers in the dentine composite. I am trying to simulate that crack arresting property by modelling the DEJ region with user element facility in abaqus with crack arresting or crack healing capabilities.

Can some body help me in this regard ?

remove order in piezoelectric matrix

I'm working in a iterative method with piezoelectric composites. During the implementation (in MATLAB) I work with the piezolectric components in a single matrix, reduced to a vector by the Hill algebra. However, I'm having problems because of the different orders of the components values. I know there is a way to normalize all the values, but it can't be by dividing the whole matrix by the same number, so, if anybody can help me I will appreceite it. You answer here or write me to naecita@gmail.com

Thanks.

How to add a picture in my program?

Hi every body,

I write a program which draws the shear and bending moment diagrams of a simple beam on matlab.inputs are loads(couples,forces,constant distributed forces and and linear distributed forces) and outputs are shear diagram and bending moment diagram. I want to add free body diagram of the beam too,but i don't know how can I do it,Can anybody help me to solve this problem?

3rd Southern California Symposium on Flow Physics - Saturday, April 18 2009 - UC San Diego

We are pleased to announce the 3rd Southern California Symposium on Flow Physics - or "SoCal Fluids III" - which will take place on the campus of UC San Diego on Saturday, April 18, 2009. The 1st symposium was held in 2007 at Caltech (with 85 participants), and in 2008 at UCLA (with 92 participants). During this one-day exchange of ideas in an informal and collaborative atmosphere, we are inviting postdocs and graduate students to give short APS-style presentations on their research.  All faculty and undergraduate students are also highly encouraged to attend.

Postdoc Position Available

Postdoc research fellows are needed in computational material science.  Experience in molecular level simulation of polymer/metal interfaces or CNT/Si and CNT/Cu interfaces are required.  Please send detailed academic CV to Jianmin Qu at jq@gatech.edu

composite material

Is it possible to find out the number of cycles to failure for a composite material(glass-epoxy) in ansys,with the data known only for material properties,layup,fibre orientaion?The beam (i.e.solid 191 taken for analysis of composite) is to be considered to be given a displacment at one end.

KINDLY HELP ME OUT BY GIVING THE DETAILED PROCEDURE

Loading X, Y, and strain data from multiple files in Tecplot 360

Dear All

 

I am using tecplot to visualize my data. Now I came across a problem as I have three files (created using Matlab). Each file is having a big matrix having data. One file is having X coordiates, second one is having Y coordinates and third one is having the strain data of these two coordinates. I like to import and plot contour using this data. It will be nice if some one can guide me in this matter.

 

Regards

 

 

PhD scholarship in mechanical engineering at University of Seville, Spain

One PhD scholarship (only for European citizens), funded by the Spanish local government of Andalucia, is currently available in the Department of Structures and Construction at the University of Seville (Spain). The PhD position is associated to the Project “Partitioned formulations for dynamic and contact problems” with Professor Ramon Abascal and Professor Jose A. Gonzalez (japerez@esi.us.es) as principal researchers.
