Equilibrium and stability of dielectric elastomer membranes undergoing inhomogeneous deformation

Submitted by Tianhu He on

Dielectric elastomers are capable of large deformation subject to an electric voltage, and are promising for uses as actuators, sensors and generators. Because of large deformation, nonlinear equations of state, and diverse modes of failure, modeling the process of electromechanical transduction has been challenging.  This paper studies a membrane of a dielectric elastomer deformed into an out-of-plane, axisymmetric shape, a configuration used in a family of commercial devices known as the Universal Muscle Actuators. 

Recommending a book on FSI with recent discussion on Immersed Boundary/Continuum Methods

I am writing to recommend my book “Fundamentals of Fluid-Solid Interactions-Analytical and Computational Approaches” recently published by Elsevier Science.  The book is available in amazon.com webpage  or Elsevier Science webpage.  The following is

Tom Milnes' First Blog Entry

Submitted by milnes on

Hi All,

--I have taken 3 previous courses in solid mechanics. 

--My undergraduate major was mechanical engineering, with a concentration in vehicle dynamics.

-- My strength is that I've had some of this material before.  My weakness is that I haven't seen it for a few years.

--I'm a masters student so I don't have a research group.  I do work part time for a hedge fund though.

--Solid mechanics will add an interesting dimension to my education.

PS2 Question 6

Submitted by Pratheev Sreetharan on

I have not taken any courses focusing on mechanics before, though ES51 (Computer Aided Machine Design) briefly touched on some topics.  My undergraduate major was Physics.  My strengths will be my comfort with mathematics as well as my exposure to professor Howard Stone's undergraduate class in Fluid Mechanics (ES123).  My weakness will definitely be my lack of exposure to any other mechanics courses.

Scholarships for Computational Mechanics in the UK for non-EU students

Submitted by Stephane Bordas on

Dear non-EU students who want to study in the UK,

You are encouraged to look at the fellowship offers below. If you qualify for these and are interested in working in a dynamic group in computational mechanics in Glasgow, please contact me directly stephane dot bordas at gmail dot com

 Our department has a growing team of PhD students (more than 20 at the moment) working in cognate disciplines, which will give you a unique opportunity for a strong PhD in computational mechanics. 

Error runing LS-DYNA explosion model, NEED HELP ?

Submitted by aaj on

Hello There

I as a student of master of structural engineering, try to do a project on simulating the effect of explosion on the concrete by using LS-DYNA as the hydrocode.

I've a problem running my model, that is an error by means of insufficient memory (about 900,000,000 words short), and I'm not able to increase it beyond 300,000,000. Then if there is anything that could help I'll be very appreciated if you could announce.

Looking forward your comment?
