Dear guys,

Can some persons help me please? How to get zero thickness cohesive element zone by abaqus cae. I am in a rush, please?

I really appreciate your help!

Like others, I'm very sorry to learn of Jerry Marsden's passing. He kindly helped all who asked (including me) despite a very busy life and recent illness. It seems fitting to mention this before citing him below. 

According to Marsden/Hughes (Mathematical Foundations of Elasticity), stretch & shear (from homogeneous elastic deformation) are determined soley by U in the polar decomposition of the deformation gradient F=RU where R = rot'n & U = right stretch.

Hi,

I'm looking for a faculty, post doctoral, or research position in the United States.

Current residence is El Paso Texas, can change depending on vacancy location and benefits. Professional experience; 26 years, 24 teaching and part time technical, 2 years management. 

Any ideas on how to mesh a complex volume in ANSYS? I have a 3D model, which is composed of various "added" volumes (meanning, I have only one unit complex volume). Please let me know your opinion in this regard. Thanks.

hi friends am doin my my project on" FEA of plasticity induced crack closure". my specimen size is 80*80 mm. by using symmetry condition i modelled 1/4th of model in ANSYS. therfore i created 40*40 mm plate. with initial crack length of 4mm.means its MT specimen of 80*80mm with 8 mm crack length, by symmetry condition i modelled 40*40 with 4mm crack lenth.

what should be the abaqus damage evolution parameters for the case of deformable body (aluminium plate) impacted by rigid projectile. the damage initialisation criteria is J-C model...

thanks in advance

Hello all,

I am implementing a Finite Shell element in Abaqus as a User Element.  I have a question regarding the Residual Lod vector that has to be defined in the User Element Subroutine.  

We know that K(du)=R-f       where R is the external force vector at time t+dt

                                                  f is the internal force vector at time t which depends on the present stress state

Hi,

All, 

The Department of Mechanical Engineering at the Catholic University of America (Washington DC) offers yearly a Fellowship to attract new Ph.D. students to the program. This Fellowship is currently available.

Dear all,

I am searching UMAT or numerical algorithm for anisotropic model for soil (clay).

Please  give me the link if u have one.

Thank You in advance  

The Department of Civil and Environmental Engineering at the University of Pittsburgh invites applications for a full-time tenure-track faculty position in theoretical, computational, and/or experimental research in the general area of Structural Engineering and Mechanics effective September 1, 2011.  The appointment is expected to be at the Assistant Professor level, although exceptional applicants at higher ranks will be given serious consideration.

SoftInWay invites engineers to take part in free 1-hour webinar "Design of High Efficiency Steam Turbine in AxSTREAM" that will take place on Thursday, October 21, 2010, at 10 a.m. and 4 p.m. EST.

The webinar demonstrates the steps of steam turbine design on 1D/2D level, with particular focus on influence of different factors on turbine efficiency at the following stages of design:

- 1D Preliminary design and optimization: number of stages, geometrical and structural constraint

What are the differences between "mechanical" and "rheological" properties?

Are "mechanical" properties a subset of "rheological" properties or vice versa? Or do they merely overlap?

Hi

how SPL (sound pressure level) is measuredin a building or roomtest space?

especially I want to know what time is needed for measurement of SPL?

I mean because SPL definition has a time integral, (this quantity is measured in special interval of time)

I need to know how long is needed for measuring SPL ?

in other words what is interval of time integral in definition of SPL?

thanks alot

All, I am conducting a survey and your response would be very much appreciated. The purpose of the survey is to gather data that will help the developers of open source software improve the success of their projects. All replies received before midnight Sunday 26th September will be entered into a draw for a £30 Amazon gift voucher. Here is a link to the survey: Click here to take survey Thanks for your participation! Lee Margetts
