In a recent discussion it was suggested that it would be useful to perform tension tests on collagen fibrils. We have developed a MEMS-based experimental procedure that is capable of applying very large strains to individual collagen fibrils. The attached paper presents illustrative data; an upcoming paper will present much more data that illustrates the rich behavior of these fibrils during loading and unloading tests.
Here is a Lectureship in Solid Mechanics available in the Engineering Science Department at Oxford posted by Prof.Alan Cocks.
The mini-symposium focuses on the link between the traditional materials modeling
and computational description of existing and new classes of materials, advanced and composite
materials and their applications. In particular, the mini-symposium is devoted to computational
characterization of material response and processing of material microstructures in the presence
of multiple temporal and spatial scales as well as multiple physical processes, and computational
For 31 mode piezoelectric plate. I have measured it's electric impedance spectrum (curve of Log IZI~ Frequency). I found that, when I used this plate for a piezoelectric sensor to receive mechanic signals. the maximum output occured at antiresonance frequency; For example, for piezoelectric hydrophone or receiving-type piezoelectric transducers, It works at antiresonance frequency (at the maximum electric impedance).
I am currently working on a project to model DCB test in ABAQUS. My current problem lies in understanding cohesive zone modelling. I was wondering if anyone can forward me a couple of materials regarding the introduction of cohesive zones?
This would help me understand the material greatly and help me in modelling the DCB test.
Another question in ABAQUS: how do you implement the material properties for cohesive elements? in particular, what values should i be using for them? e.g. E, G1, G2?
We are currently offerring an introductory course on mechanics for junior students for all fields and subjects. It is a so called general knowledge course for students to know more on certain subjects and fields before a decision on choice of a major is made. Since the Mechanics Department in our University has not been popular for so long, we have decided to evangalize our field with more glorious history of Mechanics: Newton, Bernoulli, Euler, Clausius, Faraday, and Einstein.

To coincide with this year’s IMECE in Boston, the Fracture and Failure Mechanics Technical Committee is organizing a series of sessions to honor Professor John W. Hutchinson’s seminal contributions as he moves into semi-retirement. The organizers request abstracts in contemporary research related to fracture and failure mechanics. Topics that relate to Professor Hutchinson's many past and present research activities in other areas are also welcome.
I have been working in composites for sometime now. In the literature I have found that the words "Representative Volume Element" (RVE) and "Unit Cell" (UC) are used frequently. Some authors treat them differently and some treat them same. I am little bit confused can anyone PLEASE clarify the situation or suggest some good papers to read.
Thanks In Advance.
