education

If you are teaching a course on vehicle dynamics, navigation, robotics, or rotations you might be interested in exploiting the factthat your students' smartphones are equipped with inertial navigation units (IMUs).Daniel Kawano and Prithvi Akella have harnessed the data from the IMU using the Matlab mobile app and used this data to determine the motion of a smart phone:

One Ph.D position is open for Fall 2018 in Mechanical Engineering at the Univesrity of New Hampshire.

The student will work on the NSF/CAREER project on Mechanics of Chiral Auxetic Mechanical Metamaterials.

(theory, finite element simulations, 3D printing, and mechanical experiments)

The candidate will also have opportunity to apply for the CEPS fellowship.

Several Ph.D. student positions are available in Professor El-Azab’s group with the School of Materials Engineering, Purdue University. The group performs advanced theoretical and computational research in the areas of mesoscale plasticity and dislocation dynamics, radiation effects in materials, microstructure evolution, phase field method development, and computational methods for materials science and mechanics. Applicants with MS in mechanical, aerospace, or materials engineering, with background in microstructure science, continuum mechanics and elasticity, numerical methods or computational techniques such as finite element method are highly preferred. Knowledge of at least one advanced programming language such as Fortran or C++ is required. Exceptional applicants with BS degree will also be considered. The openings are for spring 2018, summer 2018 and fall 2018. Applicants must meet Purdue University and School of Materials Engineering admission criteria. For inquiry please send email to Professor El-Azab (aelazab@purdue.edu).

Hello.

I study solid mechanics at a graduate school.

I tried to derive tangent modulus of the Mooney-Rivlinbased Neo-Hookeanmaterial.

There might be no error in my derivation, but answer is wrong with referred right answer.

So, could you check my derivation?

I attached my derivation as a figure.

Thanks in advance.

Hi all,

I am looking for a general definition of the derivative of a tenorial product (e.g. when the expression for Stress contains nonlinear terms in deformation gradient,F).

I start with a very simple example:

∂F_pq/∂F_mn = δ_pmδ_qn , i.e. Kronecker delta with first index of F_pq and first index ofF_mn, and second Kronecker delta for second pair of indices q & n.

This video (LINK) attempts to give the big picture of solid mechanics along with the brief explanation of the constituent topics.

This is an educational outreach initiative targeted at all engineers interested in mechanics and seek simpler explanations. Kindly share if you learn something out of this !

Thanks,

Prithivi

材料科学与该文的部门g at Texas A&M University invites applications for a tenured or tenure-track faculty position in the area of mechanical behavior of advanced structural materials. Although candidates at the assistant professor level are preferred, exceptionally well qualified candidates will be considered for appointment at the rank of associate or full professor.
