[June 5 | USNC/TAM2018] Short-course on data-driven modeling in mechanics and materials science
Dear colleagues in academia and industry,
We are organizing the first short course on data-driven computational mechanics and materials science at the 18th US National Congress on Theoretical and Applied Mechanics (USNC/TAM) in Chicago on June 5th, 2018. See description of short-course SC007 in the following website: http://sites.northwestern.edu/usnctam2018/short-courses/
A Geometric Perspective on Gimbal Lock in the Apollo program
The phenomenon of gimbal lock rose in prominence during the time of NASA's Apollo program. Inside the inertial measurement unit of the Apollo spacecraft was a stable (inertial) platform about which the spacecraft rotated. The hinged platform was suspended in two gimbals to give it three degrees of freedom. Its role was to give an accurate measure of the spacecraft's orientation. At a particular orientation of the spacecraft, the gimbals became coplanar and control torques became ineffective at stabilizing the platform.

Solving Nonlinear PDEs with a priori accuracy using wavelets
We present a numerical method which exploits the biorthogonal interpolating wavelet family, and second-generation wavelets, to solve initial–boundary value problems on finite domains. Our predictor-corrector algorithm constructs a dynamically adaptive computational grid with significant data compression, and provides explicit error control. Error estimates are provided for the wavelet representation of functions, their derivatives, and the nonlinear product of functions.
PhD Opening in Computational Mechanics
Two PhD positions (research assistants) are available in the Department of Mechanical Engineering within the Purdue School of Engineering and Technology at Indiana University–Purdue University Indianapolis (IUPUI). The full-support position is available for Fall 2018. The projects are focused on conducting computational modeling and simulations of various materials, including atomistic and multiscale simulations.

Postdoc position in cardiovascular modeling and simulation at NTNU, Trondheim, Norway
One postdoc position within the field of biomechanical modeling/biomedical engineering for the cardiovascular system is available at Department of Structural Engineering at NTNU, Trondheim, Norway. The position will be organized under the cardiovascular modeling project headed by professor Leif Rune Hellevik in the Biomechanics group.
EML Vol 19 is out
EML Vol 19 is out, with 7 papers. It is quite fascinating just to read the titles! There are papers on mech behaviors due to interactions within complex structures such as nanofibers in vesicles (cover), novel structures with hierarchically synchronized deformations, and mechanochemically augmented composites. There are studies of cool materials from twinning phosphorene to single layer borophene. And there are papers on methods (full-volume displacement mapping with dualMRI) and device (triboelectric generator). Can’t wait to read the content!
