Free Surface Domain Nucleation in a Ferroelectric under an Electrically Charged Tip
by Lun Yang and Kaushik Dayal, Carnegie Mellon University
Abstract
Hi,
I am relatively new in abaqus environment and i have a question about relatively easy topic. But i would like to ask kindly for your assistance.
I a working on a model - regarding bending of tubes. I would like to connect or constraint 4 elements (rigid or deformable it doesnt matter - placed in one plane, equaly spaced in one plane, around the tube's lonitudial axis),
to a single Ref. point positioned in the center axis of the tube. I want to do that in oredr to achieve behaviour of this 4 elements composition, as one. Therefore. by adding load to

为了更好地聚集海外优秀人才、培养国际一流的青年学者、及借此加快建设世界高水平大学的进程，西安交通大学建立了一个新型的、采用美国先进的用人和科研体制管理的研究中心---“国际应用力学中心” International Center for Applied Mechanics (ICAM)。该中心的目标是聚集和培养一流人才，产出一流学术成果，打造国际一流的力学学科。ICAM以独立的tenure-track PI为本，将重点研究国际力学前沿问题及国家重大需求中的关键力学问题，承担国家级的重点和重大项目，并开展高层次国际合作与交流。
Fully funded Ph.D. positions are available in the Department
of Mechanical Engineering & Engineering Science at the University of North
Carolina at Charlotte. The research focus will be on developing and using multiscale methods for modeling nanocomposites and nanomaterials. Candidates should have a BS or MS degree in
mechanical engineering, material science, civil engineering or other related
areas. Computational experience at the continuum or molecular level is
preferred but is not necessary. Interested
candidates please send a CV to atabarra [at] uncc.edu (atabarra[at]uncc[dot]edu)
I would be very grateful for a help!
Representatives from several countries have contacted the Local Organising Committee of ICTAM2012 (http://www.ictam2012.org/) to say that many of their colleagues had found it impossible to meet the deadline of 9 January, because it was too close to their countries’ winter holidays, and requesting an extension. The organisers therefore announce an extension until 24.00 hours (Beijing time) on Thursday 19 January, 2012, by which time all short papers must be received.
Study on the properties of inhomogeneous media plays a central role throughout the history of physics, e.g.
Possion’s theory on magnetism of composites, Faraday’s dielectric model of composites, Maxwell’s and later
Rayleigh’s work on conductivity of composites, and Einstein’s thesis on viscosity of fluid-particle media. As
a special branch of this field, percolation research on phase transition and critical phenomena was originated
with lattice percolation theories in 1950s [1]. The idealization of a lattice structure is convenient for analytical

Hi All,
The derivative of C (Right Cauchy-Green Tensor) with respect to F (Deformation Gradient) is computed very easily, but I'm not sure if there is an explicit way to compute the derivative of F with respect to C.
