Hi, I am Roberto Soares and I am a PhD student in Engineering Mechanics at UNL. My undergrad is from Brazil in Civil Engineering (Federal University of Ceara) and my Master’s in Engineering Mechanics from UNL. In the past I had the chance to take Continuum Mechanics, Adv Mechanics of Materials, FEM and several courses in Materials.
Fracture in bone is a complex process that depends on the volume fraction (the relative fraction of bone tissue vs. void space), the architecture (the geometrical arrangement of the tissue), the mechanical properties of the bone tissue itself, and the applied loads. Theoretical approaches to the fracture of porous materials have been developed but their application to bone may be limited as they assume homogeneity of both the structure and the underlying material. The adaptation of the mechanical properties of bone to its loading history results in substantial heterogeneity of mechanical properties primarily due to the wide range of loads applied in the skeleton. Furthermore, bone diseases as well as pharmaceutical treatments for bone diseases can also affect the heterogeneity of material properties. All the above effects are intricately linked with bone micro-structure which incorporates collagen and mineral at the nanoscale in widely varying topological manners. With a wide ranging heterogeneity in length-scales of bone fracture it becomes imperative that fracture and failure analyses of bones are carried out at multiple lengthscales using a combination of modeling and experimental approaches. In this mini-symposium computational, experimental, and theoretical presentation of research on analyzing fracture of cortical as well as cancellous bone architectures are solicited. Presentations on computational and theoretical method development, experimental behavior characterization, and forming a link between theory and experiments are all strongly encouraged.
I am working in the field of microfluidics. I wish apply Reproducing Kernel Method to solve flow problems. Can anybody help me to send the paper "Reproducing Kernel Methods ", Wing Kam Liu, Sukky Jun, Yi Fei Zhang, International Journal for Numerical Methods in Fluids, Vol.

So far we have been mainly concerned with systems of a single independent variable: energy (node/4878). We now consider a system of two independent variables: energy and volume. A thermodynamic model of the system is prescribed by entropy as a function of energy and volume.
The partial derivatives of the function give the temperature and the pressure. This fact leads to an experimental procedure to determine the function for a given system.
The laws of ideal gases and osmosis are derived. The two phenomena illustrate entropic elasticity.
Hello,
I am facing a difficulty in calculating the force at an internal node using *GET command in ANSYS. I came across some similar log on xansys, but the response was "vague" (i couldnt make out).
Hi All, Simulations and experimental results show the wide range of values for Young’s modulus (0.5 to 5.5 TPa) and wall thickness (0.066 to 0.34 nm) of carbon nanotubes (CNTs) in literature. Most of the published results say that the set of values (Young’s modulus and wall thickness of CNT) are 1 TPa and 0.34 nm, and the product is around 0.34 TPa-nm. In my point of view this set of values may be appropriate for multi-walled carbon nanotubes. Can we use the same set of values for analysis of single-walled carbon nanotubes (SWCNTs)? The interlayer distance between the graphene layers is 0.34 nm. Can we use this value as wall thickness of SWCNT or do we need to use atomic thickness instead of 0.34 nm?
Dear Colleagues:
You are cordially invited to submit an abstract to the symposium on "Nanostructured Materials including Nanocrystalline Materials, Nanoporous Materials, Active Nanomaterials and Structures." This mini symposium is listed under Track 21 -- Processing and Engineering Applications of Novel Materials as (21-2 Symposium on Multifunctional Materials and Structures) at the 2007 ASME IMECE, which will be held on Nov. 12-15, 2007 in Seattle, Washington.
Hi everyone. My name is Michael Mahoney and I'm currently enrolled in the fracture mechanics course at the University of Nebraska. I am pursuing my master's degree in engineering mechanics. My advisor is Dr. Joseph A. Turner and my research is in acoustoelastic methods for characterizing stress in a material. Here is a link to our research group: http://em-jaturner.unl.edu/.
Dear Colleague,
We are pleased to announce that the ICCES08( International Conference on
Computational and Experimental Engineering & Sciences) will be held at the
Waikiki Beach Marriott Resort & Spa, in Honolulu, Hawaii, during 17-22 March
2008.
Deadlines:
. 1 Oct 2007: Deadline for Mini-symposia proposals (email: icces [at] icces.org (icces[at]icces[dot]org)).
. 1 Oct 2007: Start abstract submission (http://www.icces.org).
. 15 Dec 2007: Deadline for abstract submission.
. 20 Dec 2007: End of abstract selection.
. 1 Jan 2008: Start early registration & hotel reservation (at discounted
rates).
. 15 Jan 2008: Deadline for early registration.
. 1 Feb 2008: Deadline for final 6-page paper submission to:
http://submission.techscience.com/icces08.
. 1 Feb 2008: Technical program announcement.
. 1 Mar 2008: Deadline for the regular registration.
The conference hotel is in a tourist area of the Waikiki Beach in Honolulu.
For those that make reservations by 1 January 2008, the hotel offers a
substantially discounted rate of about US$149/night (single or double
occupancy) (The room rates in Honolulu are normally about $265/night in
Waikiki). The conference deadlines above have been chosen to facilitate
inexpensive hotel accommodations for ALL the participants at the conference
hotel. Further details of ICCES08 will be posted continually at
http://www.icces.org. To ensure that you receive further e-mails about
ICCES08, please "sign up" at http://www.icces.org
If you are interested in hosting a mini-symposium at ICCES08, please send
us an email (icces [at] icces.org):
. The title of the Symposium,
. A brief description of the Symposium
. A list of potential participants whom you plan to invite( as comprehensive
as possible)
Each presentation at ICCES08 will be of 20 minutes duration (including
discussions). Keynote and Plenary Lectures will be of longer duration.
At ICCES08, very strict procedures will be implemented, to prevent no-shows.
Please submit an abstract, only if you intend to present the paper in
person, in good faith.
All accepted papers will appear in the open access journal, ICCES(
www.techscience.com/icces).
We look forward to welcoming you to Honolulu, Hawaii, in March 2008.
