David J. Benson is named the 2012 Ted Belytschko Applied Mechanics Award Winner.

The Applied Mechanics Award was established in 1988 by the ASME Applied Mechanics Division. The Award was renamed the Ted Belytschko Applied Mechanics Award in 2008. The Award is given to an outstanding individual for significant contributions in the practice of engineering mechanics; contributions may result from innovation, research, design, leadership or education.

Viscoelastic properties of pre- and post-cure cellular rubbers using rheometer

Submitted by farhan3d on

Hi All,

I would like to know if anyone has had the opportunity to investigate cellular rubbers rheology. I am thinking of characterizing the viscoelastic properties of cellular rubber during cure and after cure in the rheometer, using ASTM D6601. What I am expecting is a distorted cellular structure due to very constrained foam expansion during the blowing agent's decomposition, so the results would obviously be different than the ones obtained from a DMTA machine.

Would like to hear from anyone with some rheology / viscoelastic characterization experience.

Nonlinear Dynamic Structure

Submitted by othman omr ahmad on

Iam a Ph D student and I am searching for a tutorial or a book which looks into nonlinear vibration analysis of beams or dynamic large dispacement analysis of beams using ADINA method. I hope anyone can help me send me for the email: othmanomr [at] yahoo.com (othmanomr[at]yahoo[dot]com)



 

Elimination of Rigid Body Motion

Submitted by ali_mechanic_64 on

Hello everybody

 I'm doing some experimental research by the help of DIC method, But I have a huge problem that I hope someone can help me about that.  After capturing my datas, I realized that there is a constant value of rigid body motion that is added to my real datas and so that all of my results seem to be wrong. I was wondering if anyone knows how to eliminate this rigid body motion ( translation or rotation) from my datas. 

 

Thanks in Advance
