If you understand the power of visual communication to explain, explore, and extend our knowledge of the world around us, then you are invited to enter the 2007 Science & Engineering Visualization Challenge, co-sponsored by the National Science Foundation (NSF) and Science, published by the American Association for the Advancement of Science (AAAS). Entry deadline: 31 May 2007.
Vanderbilt University, Department of Civil and Environmental Engineering is seeking candidates to fill a tenure-track faculty position commencing Fall 2007. Appointment at the assistant professor level is anticipated but higher ranks will be considered for truly outstanding candidates. The successful candidate will have research and teaching expertise in structures with a research focus in one or more of the following areas: structural health monitoring, systems-scale failure analysis, dynamic control, computational mechanics and micromechanics, advanced materials (e.g., n
This is a second graduate course in solid mechanics, and explores coupled mechanical, thermal, electrical, and chemical actions. The course draws heavily upon phenomena in soft materials.

In the early days of biomechanics, there probably were not many dedicated biomechanics courses and instead a regular mechanics curriculum was studied by people interested in tissues and biosystems. However, now that there are so many dedicated bioengineering programs at Universities throughout the world, it seems as though it is more likely that much of students' basic mechanics knowledge comes through dedicated biomechanics courses. This then in turn raises the interesting question of what is taught in these courses?
Polarization switching-induced shielding or anti-shielding of an electrically permeable crack in a mono-domain ferroelectric material with the original polarization direction perpendicular to the crack is simulated by a phase field model based on the time-dependent Ginzburg-Landau equation. The domain wall energy and the long-range mechanical and electrical interactions between polarizations are taken into account. The phase field simulations exhibit a wing-shape- switched zone backwards the crack tip.
A stiff skin forms on surface areas of a flat polydimethylsiloxane (PDMS) upon exposure to focused ion beam (FIB) leading to ordered surface wrinkles. By controlling the FIB fluence and area of exposure of the PDMS, one can create a variety of patterns in the wavelengths in the micrometer to submicrometer range, from simple one-dimensional wrinkles to peculiar and complex hierarchical nested wrinkles. Examination of the chemical composition of the exposed PDMS reveals that the stiff skin resembles amorphous silica. Moreover, upon formation, the stiff skin tends to expand in the direction perpendicular to the direction of ion beam irradiation. The consequent mismatch strain between the stiff skin and the PDMS substrate buckles the skin, forming the wrinkle patterns. The induced strains in the stiff skin are estimated by measuring the surface length in the buckled state. Estimates of the thickness and stiffness of the stiffened surface layer are estimated by using the theory for buckled films on compliant substrates. The method provides an effective and inexpensive technique to create wrinkled hard skin patterns on surfaces of polymers for various applications. Click here for access to the full article.

Sandia National Laboratories, California has established the Engineering Sciences Summer Institute (ESSI) program, in which applied mechanics, structural analysis and mechanical engineering graduate students are invited to spend a summer at SNL/CA performing research that would jointly benefit the students and Sandia. The program is nine years old and a description of the program is attached. Because of the funding base for this program, we can only consider students having U.S.
Deadline for submitting an abstract: 5 March 2007.
Responding to the wishes of members, the ASME Congress will change to a new format, starting this year. Sessions will not be allocated to Divisions, but will be allocated to symposiums after abstracts are reviewed. Thus, your action item is to submit an abstract to a symposium. Here are terms as used in the 2007 Congress:
Session. Technical sessions will be scheduled for four days, Monday-Thursday. Each session will last 90 minutes, and consists of 4-6 talks. There will be 23 parallell sessions at a given time, 5 time slots for sessions per day, and a total of 23x5x4 = 460 sessions for the entire congress.
