HI
I am working on mixed mode fracture mechanics project . I was wondering what would be the appropiate mesh size to calculate the SIF of Mode 2 accurately
i am using ansys to calculate the SIF's .. I need the size of the mesh in terms of the radius of the first ring of quadratic elements .
some specifications of my project that might be helpfull
Crack size = .1 (curvilinear crack)
width = 5

Hi!
I'm a quite unexperienced ABAQUS-user and would be pleased if somebody could help me.
Hello,
I was wondering if anyone knew the equation to find the necessary clamping force to expel a saline solution out from between two parallel plates. I would like the most general form of the equation if possible, but will provide more details if necessary.
Thanks!
:)

Dielectric elastomer (DE) is a kind of electroactive polymer material,
capable of large deformation up to 380%. However, under conservative
operating conditions, DE is susceptible to instability with a small
deformation due to various modes of failure, including electrical
breakdown, electromechanical instability (EMI), loss of tension and
rupture by stretch. This paper proposes a free energy model in the
thermodynamic system of DE involving thermoelastic strain energy,
electric energy and purely thermal contribution energy to obtain the
stability conditions of all failure modes. The numerical results
indicate that the increase in temperature can markedly contribute to
improving the entropy production, the actuation stress and the critical

Given an autonomous system of Ordinary Diff erential Equations without an a priori split into slow and fast components, we defi ne a strategy for producing a large class of `slow' variables (constants of fast motion) in a precise sense. The equation of evolution of any such slow variable is deduced. The strategy is to rewrite our system on an in finite dimensional "history" Hilbert space X and defi ne our coarse observation as a functional on X.
I am looking for a Ph.D. student to work on geometric mechanics of growing bodies (both surface and bulk growth). Candidates with strong math and mechanics backgrounds are encouraged to apply. Interested candidates should email me (arash.yavari [at] ce.gatech.edu) their CV along with the names of three references.
This position has been filled.
