Modeling Fracture and Failure with Abaqus lecture notes

Hi All,

I am working on modelling the fracture failures using ABAQUS. I am searching for support where I can start on my own by following some notes.

 

If anyone has the notes related to this course conducted by Simulia please help me in getting that for me.

Modeling Fracture and Failure with Abaqus

Postdoctoral Position in Compuational Mechanics of Energetic Materials

 A postdoctoral position is available in the area of multsicale modeling of energetic materials at Rutgers University working under the supervision of Prof. Cuitino. This is a multi-investigator project which will be supported partially by the federal grants.  Candidates with a strong background in consittuvive modeling of coupled mechanical thermal chemical phenomena,  parallel finite element and multiscale methods are highly encouraged to apply.

Postdoctoral Researcher Position in Computational Materials Science

A postdoctoral researcher position is immediately available at the
Richard G. Lugar Center for Renewable Energy in Indiana
University-Purdue University Indianapolis (IUPUI). The researcher will
work on a project on studying the surface segregation phenomena in
alloy nanoparticles using atomistic simulation techniques. This project
involves close collaborations with experimental scientists. The
candidate should hold a doctor degree in a relevant discipline, such as
Materials Science, Mechanical Engineering, Chemistry, Physics, or
Chemical Engineering. The ideal candidate should have a strong
background in atomistic scale simulations (Density Functional Theory,
molecular dynamics, and Monte Carlo methods) and scientific programming

Multiple Post Doctoral Research Positions in Multiscale Modeling @ RPI

There are multiple postdoctoral positions in the Advanced Computational Research Laboratory at RPI, Troy, NY to work on multiscale modeling projects related to energy and bionanomechanics. Encouraged to apply are creative, self-motivated students with the following qualifications:

1. PhD in Computational /Applied Mechanics/ Materials Science or related topic

2. Sound background in nonlinear mechanics

3. Sound background in FEM and atomistic methods (molecular dynamics, Monte Carlo)

Research assistant and postdoc positions immediately available

My research group in the Department of Engineering Science and Mechanics at Penn State has two immediate opennings, starting from Spring of 2011.

One position targets graduate assistant, who will be working on computational biomechanics and biophysics. However, highly qualified postdoc may also be considered. 

The other position targets postdoc, who will be working on experimental single-cell mechanics, including nanoparticle-based drug delivery, cell responses to external mechanical stimuli, etc.

Assistant Professor Position at Penn State University

The Department of Mechanical and Nuclear Engineering at The Pennsylvania State University is seeking applications for an Assistant Professor position in Mechanical Engineering. The position is open for highly-qualified individuals performing research in technical areas that support our multidisciplinary mechanical engineering curriculum. Priority will be given to applicants with strong background or potential in experimental or computational approaches for biomedical systems or components. The ability to merge mechanical engineering (e.g., solid and fluid mechanics, design, acoustics, heat transfer) concepts with biomedical (e.g., bio-mechanics, imaging, implants and prostheses, microdevices) applications is highly desirable.

hi i am ganesh

currently we are doing final year project about process modelling of turning operation in ansys lsdyna.we are facing difficulty in finding out the constants required for the johnson cook material model.chip formation and failure criteria is still a major problem.so i kindly request you to give suggestion and materials to solve this problem.

Dear friends

Can you help me to find the relationship between true (Cauchy) stress and Almansi strain (constitutive equation)?

XFEM or Cohesive zone modelling how to choose "Damage Stabilization parameter"

I am working on crack propagation analysis of lamellar microstructures using XFEM. everything is working fine but i have an annoying observation that whenever i change the damage stabilization parameter let say from 1e-5 to 1e-6 then the force-displacement curves changes abruptly and the force which i am measuring on a reference node of my indenter varies two to three times. i tried to see if damage stabilization parameter effect the F-D curves and i observed that crack length and F-D curve changes.

Evoution of Yield surfaces: Past and Future Trend - Part 1

It is essential to know the amount of springback for a given forming process, so that the process or the design of the tool can be modified to obtain the desired product shape. This requires a comprehensive understanding of loading and unloading processes, and determination of elastic constants with finite plastic deformation which, in turn, require precise determination of subsequent yield surfaces.

Dynamic Analysis of Shell Element

I have some problems with my matlab code in a 9 node shell
element each node has 5 DOFs. I found that stiffness matrix for each
element is symmetric, but after transformation to global coordinate
system, the transformed stiffness matrices and the resulted global
stiffness matrix of entire shell is nonsymmetric, where order of
transpose([k]) -[k] is approximately E-18.

Mass matrix also has
been antisymmetric after transformation and so I can't solve
characteristic equation to find eigenvalues needed for dynamic analysis.

CONTACT version 10.2 released

Dear all,

Herewith I want to announc the release of CONTACT version 10.2.

The main changes with respect to earlier versions of the program are as follows:

Why penetrable model can be assumed in random?

There is a lot of homogenization theories based on penetrable model or some other name like 'overlapping', 'randomly imbedded model' to analyze random microstructure. In reality, the fibers or inclusions can not be penetrated into each other, so why they use this assumption anyway?

 

 

 Thanks for your opinion.
