Postdoctoral position at the Center for Modeling, Simulation and Imaging in Medicine at RPI

Submitted by Suvranu De on

The Center for Modeling, Simulation and Imaging in Medicine (CeMSIM) at Rensselaer Polytechnic Institute, Troy, NY, USA invites applications for a postdoctoral researcher to work on an exciting new project to develop patient specific computational models of soft biological tissues interacting with radiofrequency electric current. Of particular interest are candidates with strong background in soft tissue experimentation and computational modeling using the finite element method. There is an added opportunity to identify and develop new research agenda, technical challenges and funding opportunities as well as supervise and mentor assigned graduate students and research staff at the Center.

CEL Abaqus 6.13 impact test Solid-Water-Sand

Submitted by simumano on

Hi to everyone ,

 

I am modelling an impact problem in Abaqus6.13. The problem is all about a jack-up leg impact on seabed. I have modeled a spudcan and tank setup according to the specification of a prototype which we created in our institute. According to the problem the  impact takes place under water and creates some normal force. I compared the software results and  experimental results. I came to observe a large impact force in the software results which is no way near to my experimental results. 

 

Postdoctoral Fellow in Cardiac Biomechanics and FEA at the University of California San Francisco Medical Center

Submitted by elainetseng on

The Cardiac Biomechanics Laboratory at the University of California San Francisco Medical Center (UCSF) Division of Cardiothoracic Surgery and San Francisco VA Medical Center is seeking a hard working, motivated post-doctoral fellow to participate in biomedical engineering research involving the ascending thoracic aortic aneurysms (aTAA).  The post-doctoral fellow should be motivated to be on a career track to become an academic professor.  Our lab is NIH funded to investigate the biomechanics of aortic aneurysms.  The goals are to determine aneurysm aortic wall stress in rel

Ansys

Hi,

I have a three freedom vibrational system that has complex eigen values . I want to earn natural frequencyes it with Ansys .analytic solution system is condition space method(General Damping). In Ansys after choice Modal property in Analysis Taype,I choiced block lanczos as solution method but responses don't agree with analytic solution!! I used from Reduce,Damping,QR Damping as solution method too but natural frequencyes don't agree with analytic solution again. subspace property doesn,t exist among propertyes so I 

Deriving the jacobian matrix for the Hill criterion

Submitted by hbh on

Hello all, 

I am a beginner in UMAT implementation. I want to implement a Umat soubroutine for a kinematic hardening model using Hill's yield criterion. However, after looking in different courses and books, I remarked that the jacobian matrix derivation steps from the constitutive equations are not explicitaly defined.

Can anyone help me to understand this derivation step so that I can apply it for the Hill's criterion ?

Thank you in advance,

Regards,
Haithem

Dear colleagues,

as part of the ECCOMAS Thematic Conference X-DMS 2015 on EXTENDED DISCRETIZATION METHODS to be held in Ferrara, Italy, 9-11 September 2015 (http://x-dms2015.sciencesconf.org/), we are jointly co-organizing the mini-symposium entitled “Phase field and enhanced finite element formulations for fracture mechanics”

How to make a link between Abaqus and Fortran

Submitted by Rampa on

Hi mates

I am trying to make a link between Abaqus and Fortran. I faced a problem and have tried whatever recommended on the internet. But there is still something wrong!

I would really appreciate it if you could let me know your idea on how to resolve the problem. The error reported by "abaqus verify -user_std" has been brought, below. In fact, all requirements were recognized but at the end it is written that "Abaqus did not complete successfully".

Postdoctoral position in mechanobiology, Buffalo, New York

Submitted by ruogang zhao on

One postdoctoral position will be available in Fall, 2015 in the Department of Biomedical Engineering at the State University of New York at Buffalo (SUNY). The research area will focus on using bio-MEMS techniques to create novel cell culture platforms for cell mechanics and mechanobiological studies. Projects may involve studies of the fibrosis diseases, cancer invasion and stem cell differentiation. Some research topics can be found on our website at http://www.acsu.buffalo.edu/~rgzhao/index.html
