High order isogeometric cohesive elements for delamination analysis
Please find attached two recent papers on the use of high order B-splines/NURBS cohesive interface elements for an efficient modeling of delamination of composite laminates.
Mecahnics on the behaviour of Horizontal/laterally loaded thin hollow tubes
Dear all,
Please give some reading material on the horizontal/laterally loaded thin hollow tube, which explains with suitable formulas to calculate circumferential/hoop stresses in the thin tube subjected to lateral/horizontal loaḍ

Dear all
I urgently need the answer to my question. I am modelling a clapping or contact between two surfaces similar to a crack.
I have used abaqus : 1-tangential : frictionless 2-Hard contact
I wanna know what moelling approach does abaqus use for above situation ?
Does abaqsu use hertzian contac ? bilinear stiffness or what ?
Thank you
Postdoc Position Available in Theoretical & Applied Mechanics Group at Drexel University (Dept. of Mechanical Eng. & Mechanics)
A postdoc position is available in the Theoretical & Applied Mechanics Group (http://tamg.mem.drexel.edu/). Of particular interest are expertise in subcontinuum and continuum computational mechanics methods. Available researh projects include both alloy and composite material systems.
Applicants should submit a full CV, a statement of research and their earliest employment availability to akontsos [at] coe.drexel.edu.
Journal of Applied Mechanics (ASME Transactions) now publishes very fast.
Journal of Applied Mechanics (JAM) received 526 submitted manuscripts in 2013. Among them 4 are still in review.
The average time for the 1st round of review, with the decision to accept, or reject, or revise, is 18 days. After the 1st round of review, the average time to make the final decision is 34 days, which include both the authors' revision time and 2nd (and more) round(s) of review.
After acceptane the uneditted manuscript appears online with the assigned DOI within 48 hours.

An elastic phase field model for thermal oxidation of metals: Application to zirconia
http://www.sciencedirect.com/science/article/pii/S0927025614002031
Abstacrt: A multi-phase field model was developed for non-selective oxidation of metals which captures both the oxidation kinetics and stress generation. Phase field formulation involved a non-conserved phase field variable as the marker for the metallic substrate, oxide scale, and a fluid phase containing oxygen, and a conserved phase field variable representing the concentration of oxygen.
