While it is easy to imagine why bend testing needs to be performed on rigid materials like plastics (ASTM D790) and concrete (ASTM C1609), in reality bend test applications are common in a variety of industries. Universal testing machines equipped with bend fixtures are used to calculate flexural modulus, flexural strength, yield point, and more.

A PhD position in the area of computational materials science is available in the Department of Aerospace Engineering at the University of Cincinnati. Candidates should be strongly self-motivated individuals possessing a MS or BS degree in mechanical engineering, materials science and engineering or other closely related disciplines. This position will conduct multiphysics modeling on the MOOSE (http://mooseframework.org/) platform and a background in phase field modeling with strong c++ programming skills is desirable.

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/

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.

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.

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.
